Post-Roman kingdoms

Post-Roman kingdoms and tribes, and the Byzantine Empire after the end of the Western Roman Empire

In the post-Roman world, the fusion of Roman culture with the customs of the invading tribes is well documented. Popular assemblies that allowed free male tribal members more say in political matters than had been common in the Roman state developed into legislative and judicial bodies.^[53] Material artefacts left by the Romans and the invaders are often similar, and tribal items were often modelled on Roman objects.^[54] Much of the scholarly and written culture of the new kingdoms was based on Roman intellectual traditions.^[55] Many of the new political entities no longer supported their armies through taxes, instead relying on granting them land or rents. This meant there was less need for large tax revenues and so the taxation systems decayed.^[56]

In Britain, the local Celtic Britons' culture had little impact on the Anglo-Saxons' way of life, but the linguistic assimilation of masses of the natives to the newcomers is evident. By around 600, new political centres emerged, some local leaders accumulated considerable wealth, and a number of small kingdoms such as Wessex and Mercia were formed. Smaller kingdoms in present-day Wales and Scotland were still under the control of the native Britons and Picts.^[57] Ireland was divided into even smaller political units, perhaps as many as 150 tribal kingdoms.^[58]

The Ostrogoths moved to Italy from the Balkans in the late 5th century under Theoderic the Great (r. 493–526). He set up a kingdom marked by its co-operation between the natives and the conquerors until the last years of his reign. Power struggles between Romanised and traditionalist Ostrogothic groups followed his death, providing the opportunity for the Byzantines to reconquer Italy.^[59] The Burgundians settled in Gaul where they reorganised their kingdom.^[60] Elsewhere in Gaul, the Franks and Celtic Britons set up stable polities. Francia was centred in northern Gaul, and the first king of whom much is known is Childeric I (d. 481). Under his son Clovis I (r. 509–11), the founder of the Merovingian dynasty, the Frankish kingdom expanded and converted to Christianity.^[61] Unlike other Germanic peoples, the Franks accepted Catholicism which facilitated their cooperation with the native Gallo-Roman aristocracy.^[62] Britons fleeing from Britannia – modern-day Great Britain – settled in what is now Brittany.^{[note 4][63]}

Other monarchies were established by the Visigoths in the Iberian Peninsula, the Suebi in northwestern Iberia, and the Vandals in North Africa.^[64] The Lombards settled in Northern Italy in 568 and established a new kingdom composed of town-based duchies.^[65] Coming from the Asian steppes, the nomadic Avars conquered most Slavic, Turkic and Germanic tribes in the lowlands along the Lower and Middle Danube by the end of the 6th century, and they were routinely able to force the Eastern emperors to pay tribute.^[66] Around 670, another steppe people, the Bulgars settled at the Danube Delta. In 681, they defeated a Byzantine imperial army, and established the First Bulgarian Empire, subjugating the local Slavic tribes.^[67]

The settlement of peoples was accompanied by changes in languages. Latin, the literary language of the Western Roman Empire, was gradually replaced by vernacular languages which evolved from Latin, but were distinct from it, collectively known as Romance languages. Greek remained the language of the Byzantine Empire, but the migrations of the Slavs expanded the area of Slavic languages in Central and Eastern Europe.^[68]

Byzantine survival

The Eastern Roman Empire remained intact and experienced an economic revival that lasted into the early 7th century. Here political life was marked by closer relations between the political state and Christian Church, with theological matters assuming an importance in Eastern politics that they did not have in Western Europe.^[69] As the Byzantines regarded the eunuchs exceptionally intelligent and loyal servants, they regularly employed castrated men as state or church officials, and guardians or tutors to women and children.^[70] Legal developments included the codification of Roman law;^[71] the most comprehensive compilation, the Corpus Juris Civilis, took place under Emperor Justinian (r. 527–65).^[72]

Justinian almost lost his throne during the Nika riots, a popular revolt that destroyed half of Constantinople in 532. After crushing the revolt, he reinforced the autocratic elements of the imperial government and mobilised his troops against the Arian western kingdoms. The general Belisarius (d. 565) conquered North Africa from the Vandals, and attacked the Ostrogoths, but the campaign was interrupted by an unexpected Sasanian invasion from the east. Between 541 and 543, a deadly outbreak of plague decimated the empire's population. Justinian ceased to finance the maintenance of public roads, and covered the lack of military personnel by developing an extensive system of border forts. In a decade, he resumed expansionism, completing the conquest of the Ostrogothic kingdom, and seizing much of southern Spain from the Visigoths.^[73]

Justinian's reconquests and excessive building program have been criticised by historians for bringing his realm to the brink of bankruptcy, but many of the difficulties faced by Justinian's successors were because of other factors, including the epidemic and the massive expansion of the Avars and their Slav allies.^[74] In the east, border defences collapsed during a new war with the Sasanian Empire, and the Persians seized large chunks of the empire, including Egypt, Syria, and much of Anatolia. In 626, the Avars and Slavs attacked Constantinople. Two years later, Emperor Heraclius (r. 610–41) launched an unexpected counterattack against the heart of the Sassanian Empire bypassing the Persian army in the mountains of Anatolia; the empire recovered all of its lost territories in the east.^[75]

Western society

In Western Europe, some of the older Roman elite families died out while others became more involved with ecclesiastical than secular affairs. Values attached to Latin scholarship and education mostly disappeared. While literacy remained important, it became a practical skill rather than a sign of elite status. By the late 6th century, the principal means of religious instruction in the Church had become music and art rather than the book.^[76] Most intellectual efforts went towards imitating classical scholarship, but some original works were created, along with now-lost oral compositions. The writings of Sidonius Apollinaris (d. 489), Cassiodorus (d. c. 585), and Boethius (d. c. 525) were typical of the age.^[77] Aristocratic culture focused on great feasts rather than on literary pursuits. Family ties within the elites were important, as were the virtues of loyalty, courage, and honour. These ties led to the prevalence of the feud in aristocratic society. Most feuds seem to have ended quickly with the payment of some sort of compensation.^[78]

Women took part in aristocratic society mainly in their roles as wives and mothers, with the role of mother of a ruler being especially prominent in Francia. In Anglo-Saxon society the lack of many child rulers meant a lesser role for women as queen mothers, but this was compensated for by the increased role played by abbesses of monasteries.^[79] Women's influence on politics was particularly fragile, and early medieval authors tended to depict powerful women in a bad light.^{[note 5][81]} Women usually died at considerably younger age than men, primarily owing to infanticide and complications at childbirth. The disparity between the numbers of marriageable women and grown men led to the detailed regulation of legal institutions protecting women's interests, including their right to the Morgengabe, or "morning gift".^[82] Early medieval laws acknowledged a man's right to have long-term sexual relationships with women other than his wife, such as concubines, but women were expected to remain faithful. Clerics censured sexual unions outside marriage, and monogamy became also the norm of secular law in the 9th century.^[83]

Landholding patterns were not uniform; some areas had greatly fragmented holdings, but in other areas large contiguous blocks of land were the norm. These differences allowed for a wide variety of peasant societies, some dominated by aristocratic landholders and others having a great deal of autonomy.^[84] Land settlement also varied greatly. Some peasants lived in large settlements that numbered as many as 700 inhabitants, others on isolated farms.^[85] As legislation made a clear distinction between free and unfree, there was no sharp break between the legal status of the free peasant and the aristocrat, and it was possible for a free peasant's family to rise into the aristocracy over several generations through military service.^[86] Demand for slaves was covered through warring and raids. Initially, the Franks' expansion and conflicts between the Anglo-Saxon kingdoms supplied the slave market with prisoners of war and captives. After the Anglo-Saxons' conversion to Christianity, slave hunters mainly targeted the pagan Slav tribes—hence the English word "slave" from slavicus, the Medieval Latin term for Slavs.^[87] Christian ethics brought about significant changes in the position of slaves in the 7th and 8th centuries. They were no more regarded as their lords' property, and their right to a decent treatment was enacted.^[88]

Roman city life and culture changed greatly in the early Middle Ages. Although the northern Italian cities remained inhabited, they contracted significantly in size.^{[note 6][90]} In Northern Europe, cities also shrank, while civic monuments and other public buildings were raided for building materials.^[91] The Jewish communities survived in Spain, southern Gaul and Italy. The Visigothic kings made concentrated efforts to convert the Hispanic Jews to Christianity but the Jewish community quickly regenerated after the Muslim conquest of Spain.^[92] Whereas Muslim rulers employed Jewish courtiers,^[93] Christian legislation forbade the Jews' appointment to government positions.^[94]

Rise of Islam

The early Muslim conquests

  Expansion under Muhammad, 622–632

  Expansion during the Rashidun Caliphate, 632–661

  Expansion during the Umayyad Caliphate, 661–750

Religious beliefs were in flux in the lands along the Eastern Roman and Persian frontiers during the late 6th and early 7th centuries. State-sponsored Christian missionaries proselytised among the pagan steppe peoples, and the Persians made attempts to enforce Zoroastrianism on the Christian Armenians. Judaism was an active proselytising faith, and at least one Arab political leader—Dhu Nuwas, ruler of what is today Yemen—converted to it.^[95] The emergence of Islam in Arabia during the lifetime of Muhammad (d. 632) brought about more radical changes. After his death, Islamic forces conquered much of the Near East, starting with Syria in 634–36, continuing with Persia between 637 and 642, and reaching Egypt in 640–42. The Eastern Romans halted the Muslim expansion at Constantinople in 674–78 and 717–18. In the west, Islamic troops conquered North Africa by the early 8th century, annihilated the Visigothic Kingdom in 711, and invaded southern France from 713.^[96]

The Muslim conquerors bypassed the mountainous northwestern region of the Iberian Peninsula. Here a small kingdom, Asturias emerged as the centre of local resistance.^[97] The defeat of Muslim forces at the Battle of Tours in 732 led to the reconquest of southern France by the Franks, but the main reason for the halt of Islamic growth in Europe was the overthrow of the Umayyad Caliphate and its replacement by the Abbasid Caliphate. The Abbasids were more concerned with the Middle East than Europe, losing control of sections of the Muslim lands. Umayyad descendants took over Al-Andalus (or Muslim Spain), the Aghlabids controlled North Africa, and the Tulunids became rulers of Egypt.^[98] The Islamisation of the countryside in Al-Andalus was slow. Christians were regularly employed in state administration, but sometimes violent interreligious conflicts led to their mass migration to the north.^[99] Apart from Byzantium, Muslim Spain was the only place in Europe where eunuchs played a preeminent role in administration and social life, holding positions such as guardians of religious shrines, or harem servants.^[100]

Trade and economy

As the migrations and conquests disrupted trade networks throughout the old Roman lands, goods from long-range trade were replaced with local products. Non-local goods appearing in the archaeological record are usually luxury goods or metalworks.^[101] In the 7th and 8th centuries, new commercial networks were developing in northern Europe. Goods like furs, walrus ivory and amber were delivered from the Baltic region to western Europe. Conflicts over the control of trade routes and toll stations were common.^[102] In the post-Roman kingdoms, base metal coinage nearly ceased but Roman bronze coins remained in circulation for centuries. Although gold coins were struck, they were mainly spent for extraordinary expenditures, such as the purchase of land or luxury goods. A shift from gold coinage to the mint of silver pennies began in the late 7th century, not independently of the cessation of Byzantine subsidy payments to the Lombards and Franks. The elites' new emphasis on Christian charity also increased the demand for coins of lower value.^[103]

The flourishing Islamic economies' constant demand for fresh labour force and raw materials opened up a new market for Europe around 750. Europe emerged as a major supplier of house slaves and slave soldiers for Al-Andalus, northern Africa and the Levant. Venice developed into the most important European center of slave trade.^[104][105] In addition, timber, fur and arms were delivered from Europe to the Mediterranean, while Europe imported spices, medicine, incense, and silk from the Levant.^[106] The large rivers connecting distant regions facilitated the expansion of transcontinental trade.^[107] Contemporaneous reports indicate that Anglo-Saxon merchants visited fairs at Paris, pirates preyed on tradesman on the Danube, and Eastern Frankish merchants reached as far as Zaragoza in Al-Andalus.^[108]

Church life

The idea of Christian unity endured, although differences in ideology and practice between the Eastern and Western Churches became apparent by the 6th century.^[109] The formation of new realms reinforced the traditional Christian concept of the separation of church and state in the west, whereas this notion was alien to eastern clergymen who regarded the Roman state as an instrument of divine providence.^[109] In the late 7th century, clerical marriage emerged as a permanent focus of controversy. After the Muslim conquests, the Byzantine emperors could less effectively intervene in the west. When Leo III (r. 717–41) prohibited the display of paintings representing human figures in places of worship, the papacy openly rejected his claim to declare new dogmas by imperial edicts.^[110] Although the Byzantine Church condemned iconoclasm in 843, further issues such as fierce rivalry for ecclesiastic jurisdiction over newly converted peoples, and the unilateral modification of the Nicene Creed in the west widened to the extent that the differences were greater than the similarities.^[111] In the west, the tithe, originally a voluntarily contribution, was levied as a regular church tax on agrarian products from the 10th century.^[112]

Few of the Western bishops looked to the papacy for leadership. The only part of Western Europe where the papacy had influence was Britain, where Gregory had sent the Gregorian mission in 597 to convert the Anglo-Saxons to Christianity.^[113] Irish missionaries were most active in Western Europe between the 5th and the 7th centuries.^[114] People did not visit churches regularly. Instead, meetings with itinerant clergy and pilgrimages to popular saints' shrines were instrumental in the spread of Christian teaching. Clergymen used special handbooks known as penitentials to determine the appropriate acts of penance—typically prayers, and fasts—for sinners. They placed a special emphasis on sexuality and prescribed severe penances for adulterers, fornicators and those engaged in non-reproductive sexual acts, such as homosexuals.^[115] In contrast, the Bogomils of the Balkans condemned sexual reproduction as they regarded Satan the creator of the physical universe.^[116]

The Early Middle Ages witnessed the rise of Christian monasticism. Monastic ideals spread from Egypt through hagiographical literature, especially the Life of Anthony. Most European monasteries were of the type that focuses on community experience of the spiritual life, called cenobitism.^[117] The Italian monk Benedict of Nursia (d. 547) developed the Benedictine Rule which became widely used in western monasteries.^[118] In the east, the monastic rules compiled by Theodore the Studite (d. 826) gained popularity after they were adopted in the Great Lavra on Mount Athos in the 960s, turning the mount into the most important centre of Orthodox monasticism.^[119]

Monks and monasteries had a deep effect on religious and political life, in various cases acting as land trusts for powerful families and important centres of political authority.^[120] They were the main and sometimes only outposts of education and literacy in a region. Many of the surviving manuscripts of the Latin classics were copied in monasteries.^[121] Monks were also the authors of new works, including history, theology, and other subjects, written by authors such as Bede (d. 735), a native of northern England.^[122] The erudite Saxon nun Hrosvitha (d. 1000) authored the first non-liturgical medieval dramas.^[123][124] The Byzantine missionary Constantine (d. 869) developed Old Church Slavonic as a new liturgical language, establishing the basis for flourishing Slavic religious literature; around 900 a new script was adopted, now known for Constantine's monastic name as Cyrillic.^[125]

In Western Christendom, lay influence over Church affairs came to a climax in the 10th century. Aristocrats regarded the churches and monasteries under their patronage as their personal property, and simony—the sale of Church offices—was a common practice. Simony aroused a general fear as many believed that irregularly appointed priests could not confer valid sacraments such as baptism.^[126] Monastic communities were the first to react to this fear by the rigorous observance of their rules. The establishment of Cluny Abbey in Burgundy in 909 initiated a more radical change as Cluny was freed from lay control and placed under the protection of the papacy. The Cluniac Reforms spread through the founding of new monasteries and the reform of monastic life in old abbeys.^[127] Cluny's example indicated that the reformist idea of the "Liberty of the Church" could be achieved through submission to the papacy.^[128]

Carolingian Europe

The Merovingian kings customarily distributed Francia among their sons and destroyed their own power base by extensive land grants. In the northeastern Frankish realm Austrasia, the Arnulfings were the most prominent beneficiaries of royal favour. As hereditary Mayors of the Palace, they were the power behind the throne from the mid-7th century. One of them, Pepin of Herstal (d. 714), also assumed power in the central Frankish realm Neustria. His son Charles Martel (d. 741) took advantage of the permanent Muslim threat to confiscate church property and raise new troops by parcelling it out among the recruits.^[129]

The Carolingians, as Charles Martel's descendants are known, succeeded the Merovingians as the new royal dynasty of Francia in 751. This year the last Merovingian king Childeric III (r. 743–51) was deposed, and Charles Martel's son Pepin the Short (r. 751–68) was crowned king with the consent of the Frankish leaders and the papacy. Pepin attacked the Lombards and enforced their promise to respect the possessions of the papacy. His subsequent donation of Central Italian territories to the Holy See marked the beginnings of the Papal States.^[130][131]

Pepin left his kingdom in the hands of his two sons, Charles, more often known as Charlemagne (r. 768–814), and Carloman (r. 768–71). When Carloman died of natural causes, Charlemagne reunited Francia and embarked upon a programme of systematic expansion, rewarding allies with war booty and command over parcels of land. He subjugated the Saxons, conquered the Lombards, and created a new border province in northern Spain.^[132] Between 791 and 803, Frankish troops destroyed the Avars which facilitated the development of small Slavic principalities, mainly ruled by ambitious warlords under Frankish suzerainty.^{[note 7][134]} The coronation of Charlemagne as emperor on Christmas Day 800 marked a return of the Western Roman Empire although the Byzantines did not recognise him as a second "emperor of the Romans".^[135]

The empire was administered by an itinerant court that travelled with the emperor, as well as approximately 300 imperial officials called counts, who administered the counties the empire had been divided into.^[136] The central administration supervised the counts through imperial emissaries called missi dominici, who served as roving inspectors and troubleshooters. The clerics of the royal chapel were responsible for recording important royal grants and decisions.^[137]

Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,^{[note 8]} allowing a common writing style that advanced communication across much of Europe. Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. New works on religious topics and schoolbooks were also produced.^[139]

Breakup of the Carolingian Empire

Territorial divisions of the Carolingian Empire in 843, 855, and 870

Charlemagne continued the Frankish tradition of dividing his empire between all his sons, but only one son, Louis the Pious (r. 814–40), was still alive by 813. Louis's reign was marked by numerous divisions of the empire among his sons, and civil wars between various alliances of father and sons over the control of various parts of the empire. Three years after his death, his three surviving sons divided the empire into three by the Treaty of Verdun.^[140] A kingdom between the Rhine and Rhone rivers was created for Lothair I (r. 817–55) to go with his lands in Italy, and his imperial title was recognised. Louis the German (r. 843–76) was in control of the eastern lands in modern-day Germany. Charles the Bald (r. 843–77) received the western Frankish lands, comprising most of modern-day France.^[141] Charlemagne's grandsons and great-grandsons divided their kingdoms between their descendants, eventually causing all internal cohesion to be lost.^[142]

There was a brief re-uniting of the empire by Charles the Fat in 884, although the actual units of the empire retained their separate administrations.^[143] By the time he died early in 888, the Carolingians were close to extinction, and non-dynastic claimants assumed power in most of the successor states, such as the Parisien count Odo in Francia (r. 888–98).^[144] In the eastern lands the dynasty died out with the death of Louis the Child (r. 899–911), and the selection of the Franconian duke Conrad I (r. 911–18) as king.^[145] In West Francia, the dynasty was restored first in 898, then in 936, but the last Carolingians were unable to keep the aristocracy under control. In 987 the dynasty was replaced, with the crowning of Hugh Capet (r. 987–96) as king.^{[note 9][146]} Although the Capetian kings remained nominally in charge, much of the political power devolved to the local lords.^[147]

Frankish culture and the Carolingian methods of state administration had a significant impact on the neighboring peoples. Frankish threat triggered the formation of new states along the empire's eastern frontier—Bohemia, Moravia, and Croatia.^[148] The breakup of the Carolingian Empire was accompanied by invasions, migrations, and raids by external foes. The Atlantic and northern shores were harassed by the Vikings, who also raided the British Isles and settled there. In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish king Charles the Simple (r. 898–922) to settle in what became Normandy. The eastern parts of the Frankish kingdoms, especially Germany and Italy, were under continual Magyar assault until the invaders' defeat at the Battle of Lechfeld in 955.^[149] In the Mediterranean, Arab pirates launched regular raids against Italy and southern France, and the Muslim states began expanding. The Aghlabids conquered Sicily, and the Umayyads of Al-Andalus annexed the Balearic Islands.^[150]

New kingdoms and Byzantine revival

The Vikings' settlement in the British Isles led to the formation of new political entities, including the small but militant Kingdom of Dublin in Ireland.^[151] The Anglo-Saxon king Alfred the Great (r. 871–99) came to an agreement with the Danish invaders in 879, acknowledging the existence of an independent Viking realm in Britain.^[152][153] By the middle of the 10th century, Alfred's successors had restored English control over the territory.^[154] In northern Britain, Kenneth MacAlpin (d. c. 860) united the Picts and the Scots into the Kingdom of Alba.^[155] In the early 10th century, the Ottonian dynasty established itself in Germany, and was engaged in driving back the Magyars and fighting the disobedient dukes. After an appeal by the widowed Queen Adelaide of Italy (d. 999) for protection, the German king Otto I (r. 936–73) crossed the Alps into Italy, married the young widow and had himself crowned king in Pavia in 951. His coronation as Holy Roman Emperor in Rome in 962 demonstrated his claim to Charlemagne's legacy.^[156] Otto's successors remained keenly interested in Italian affairs but the absent German kings were unable to assert permanent authority over the local aristocracy.^[157] In the Iberian Peninsula, Asturias expanded slowly south, and continued as the Kingdom of León in the 10th century. By that time, the Basques' fight for independence had led to the formation of the small Kingdom of Navarre in the Pyrenees, and the counts of Barcelona had gained autonomy in the Carolingian border province.^[158][159]

The Eastern European trade routes towards Asia were controlled by the Khazars. Their multiethnic empire resisted the Muslim expansion, and their leaders converted to Judaism.^[160] At the end of the 9th century, a new trade route developed, bypassing Khazar territory and connecting Central Asia with Europe across Volga Bulgaria; here the local inhabitants converted to Islam.^[161] In Scandinavia, contacts with Francia paved the way for missionary efforts by Christian clergy, and Christianisation was closely associated with the growth of centralised kingdoms in Denmark, Norway, and Sweden. Swedish traders and slave hunters ranged down the rivers of the East European Plain, captured Kyiv from the Khazars, and even attempted to seize Constantinople in 860 and 907.^[162] Norse colonists settled in Iceland and created a political system that hindered the accumulation of power by ambitious chieftains.^[163]

Byzantium revived its fortunes under Emperor Basil I (r. 867–86) and his successors Leo VI (r. 886–912) and Constantine VII (r. 913–59), members of the Macedonian dynasty. Commerce revived and the emperors oversaw the extension of a uniform administration to all the provinces. The imperial court was the centre of a revival of classical learning, a process known as the Macedonian Renaissance. The military was reorganised, which allowed the emperors John I (r. 969–76) and Basil II (r. 976–1025) to expand the frontiers of the empire.^[164]

Missionary efforts by both Eastern and Western clergy resulted in the conversion of the Moravians, Danubian Bulgars, Czechs, Poles, Magyars, and the inhabitants of the Kievan Rus'.^[165] Moravia fell victim to Magyar invasions around 900, Bulgaria to Byzantine expansionism between 971 and 1018.^[148][166] After the fall of Moravia, dukes of the Czech Přemyslid dynasty consolidated authority in Bohemia.^[167] In Poland, the destruction of old power centres accompanied the formation of state under the Piast dukes.^[168] In Hungary, the princes of the Árpád dynasty applied extensive violence to crush opposition by rival Magyar chieftains.^[169] The Rurikid princes of Kievan Rus' emerged as the hegemon power of East Europe's vast forest zones after Rus' raiders sacked the Khazar capital Atil in 965.^[170]

Architecture and art

New basilicas were built in the major Roman cities and the post-Roman kingdoms in the 4th–6th centuries.^{[note 10][171]} In the late 6th century, Byzantine church architecture adopted an alternative model imitating the rectangular plan and the dome of Justinian's Hagia Sophia, the largest single roofed structure of the Roman world.^[172] As the spacious basilicas became of little use with the decline of urban centres in the west, they gave way to smaller churches. By the beginning of the 8th century, the Carolingian Empire revived the basilica form of architecture.^[173] One new standard feature of Carolingian basilicas is the use of a transept, or the "arms" of a T-shaped building that are perpendicular to the long nave.^[174] The former Great Mosque of Córdoba—now the city's cathedral church—is an extraordinary monument of Moorish architecture with a forest of reused Roman columns supporting a double line of red-and-white-stripped arches.^[175]

Magnificent halls built of timber or stone were the centres of political and social life. Their design often adopted elements of Later Roman architecture like pilasters, columns, and sculptured discs.^{[note 11][176]} After the disintegration of the Carolingian Empire, the spread of aristocratic castles indicates a transition from communal fortifications to private defence in western Europe. Most castles were wooden structures but the wealthiest lords built stone fortresses.^{[note 12]} One or more towers, now known as keeps, were their most characteristic features but castles often developed into multifunctional compounds with their drawbridges, fortified courtyards, cisterns or wells, halls, chapels, stables and workshops.^[178]

In the age of mass migrations, gold pouring to the tribal leaders from the Roman Empire was regularly remoulded into new artifacts, such as massive necklaces, and eagle-shaped fibulae by local goldsmiths. Their unrealistic style, often influenced by Iranian polychrome and cloisonné metalworks, was introduced into Roman territory by the invading peoples.^[179] Artisans working for post-Roman elites developed a distinctly abstract design, characterised by ribbons and highly stylised animal motifs.^[180] Literary works, like the Old English epic poem Beowulf, and the Nordic sagas refer to great royal treasures but only a few of them survived, including the grave goods from Childeric's tomb at Tournai, and the rich Anglo-Saxon burial at Sutton Hoo. Religious art quickly assimilated several elements of the post-Roman secular style, such as strapwork ornamenting, and extensive segmentation.^[181] Paintings have mainly survived in richly decorated Gospel Books, including the Book of Kells and the Book of Lindisfarne—two representative works of the Insular art of Ireland and Northumbria.^{[note 13][183]}

The Hellenistic tradition of realistic portrayal survived in the Mediterranean.^[184] Although the iconoclastic movement restricted Byzantine art for almost a century, the iconophiles' triumph paved the way for an artistic renewal.^{[note 14][186]} The more naturalistic Mediterranean style served as an important source of inspiration for western artists during the rule of Charlemagne who treated visual arts as a powerful instrument of education and propaganda.^[187] After a long pause, Carolingian art rediscovered the human figure, and western artists often depicted people in illuminated codices.^{[note 15]} These were often protected by sumptuous book covers, made of gold, pearls, and polished gemstones.^[188] Charlemagne's court seems to have been responsible for the acceptance of figurative monumental sculpture in Christian art,^[189] and by the end of the period near life-sized figures such as the Gero Cross were common in important churches.^[190] In England, book illuminators freely enriched their Insular heritage with Carolingian motifs, such as sprigs of foliage. In Germany, manuscripts illustrated with lively pictorial cycles indicate the direct impact of contemporary Byzantine art on Ottonian artists. In Christian Spain, the use of Kufic letters and Moorish arches as decorative elements demonstrated the influence of Islamic art.^[191]

Military and technology

During the later Roman Empire, the principal military developments were attempts to create an effective cavalry force as well as the continued development of highly specialised types of troops. The creation of heavily armoured cataphract-type soldiers as cavalry was an important feature of the Late Roman military. The various invading tribes had differing emphases on types of soldiers—ranging from the primarily infantry Anglo-Saxon invaders of Britain to the Vandals and Visigoths who had a high proportion of cavalry in their armies.^[192] The greatest change in military affairs was the adoption of the Hunnic composite bow in place of the earlier, and weaker, Scythian composite bow.^[193] The Avar heavy cavalry introduced the use of stirrups in Europe,^[194] and it was adopted by Byzantine cavalrymen before the end of the 6th century.^[195] Another development was the increasing use of longswords and the progressive replacement of scale armour by mail and lamellar armour.^[196]

The importance of infantry and light cavalry began to decline during the early Carolingian period, with a growing dominance of elite heavy cavalry, although a large proportion of the armies appear to have been mounted infantry, rather than true cavalry.^[197] The use of militia-type levies of the free population declined. One exception was Anglo-Saxon England, where the armies were still composed of regional levies, known as the fyrd.^[198] In military technology, one of the main changes was the reappearance of the crossbow as a military weapon.^[199] A technological advance that had implications beyond the military was the horseshoe, which allowed horses to be used in rocky terrain.^[200]

Society

13th-century French historiated initial with the three classes of medieval society: those who prayed (the clergy) those who fought (the knights), and those who worked (the peasantry).

Severe draughts hit the Middle East, and the Eurasian Steppe experienced cold anomalies between around 950 and 1060. The ensuing famines led to riots and military coups in the Byzantine Empire, the Abbasid Caliphate, and Egypt, and forced masses of nomadic Turks to seek new pasturelands in Iraq, Anatolia, and the Balkans. Their influx caused much destruction, and culminated in the establishment of the Seljuk Empire in the Middle East.^[201] In Europe, a period of tremendous population expansion began around 1000, and the estimated population grew from 35 to 80 million by 1347. The exact causes remain unclear: improved agricultural techniques, assarting (or bringing new lands into production), a more clement climate and the lack of invasion have all been suggested.^[202][203]

Most medieval western thinkers divided the society into three fundamental classes. These were the clergy, the nobility, and the commoners. Constituting about 98 per cent of the total population, commoners were mainly rural peasants and artisans. The number of townspeople was growing but never exceeded 10 per cent of the total population.^[204][205] Feudalism regulated fundamental social relations in many parts of Europe. In this system, one party granted property, typically land to the other in return for services, mostly of military nature that the recipient, or vassal, had to render to the grantor, or lord.^[206][207] In other parts of Europe, such as Germany, Poland, and Hungary, inalienable allods remained the dominant forms of landholding. Their owners owed homage to the king or a higher-ranking aristocrat but their landholding was free of feudal obligations.^[208][209]

Many of the peasantry were no longer settled in isolated farms but had gathered into more defensible small communities, usually known as manors or villages.^[202][210] In the system of manorialism, a manor was the basic unit of landholding, and it comprised smaller components, such as parcels held by peasant tenants, and the lord's demesne.^[211] Slaveholding was declining as churchmen prohibited the enslavement of coreligionists, but a new form of dependency (serfdom) supplanted it by the late 11th century. Unlike slaves, serfs had legal capacity, and their hereditary status was regulated by agreements with their lords. Restrictions on their activities varied but their freedom of movement was customarily limited, and they usually owed corvées, or labor services.^[212][213] Peasants left their homelands in return for significant economic and legal privileges, typically a lower level of taxation and the right to administer justice at local level. The crossborder movement of masses of peasantry had radical demographic consequences, such as the spread of German settlements to the east, and the expansion of the Christian population in Iberia.^[214]

With the development of heavy cavalry, the previously uniform class of free warriors split into two groups. Those who could equip themselves as mounted knights were integrated into the traditional aristocracy, but others were assimilated into the peasantry.^[215] The new elite's position was stabilised through the adoption of strict inheritance customs, such as primogeniture—the eldest son's right to inherit the family domains undivided.^[216] Nobles were stratified in terms of the land and people over whom they held authority; the lowest-ranking nobles did not hold land and had to serve wealthier aristocrats.^{[note 16][218]} The nobility was never a closed group: kings could raise commoners to the aristocracy, wealthy commoners could marry into noble families, and impoverished aristocrats could loose their privileged status.^[219] Western aristocrats often moved to the peripheries of Latin Christendom either with the support of local rulers who appreciated their military skills, or as conquerors.^{[note 17]} French-speaking noblemen mainly settled in the British Isles, southern Italy or Iberia, whereas the German aristocrats preferred Central and Eastern Europe.^[221]

The clergy was divided into two types. The secular clergy cared for believers' spiritual needs, mainly serving in the parish churches, whereas the regular clergy lived under a religious rule as monks, canons, or friars. Churchmen supervised several aspects of everyday life, church courts had exclusive jurisdiction over marriage affairs,^[222] and church authorities supported popular peace movements in the west.^[223] The introduction of clerical celibacy—the ban on priestly marriage—clearly distinguished Catholic clergy from laity. Laypeople were obliged to confess their sins to a priest at least once a year which reinforced priestly control of their life.^[224] Individuals who were thought to receive divine revelations might present a challenge to clerical monopolies but most of them respected official doctrines. The veneration of popular mystics, such as Francis of Assisi (d. 1226), was often sanctioned by church authorities.^[225]

Women were officially required to be subordinate to some male, whether their father, husband, or other kinsman. Women's work generally consisted of household or other domestically inclined tasks such as child-care. Peasant women could supplement the household income by spinning or brewing at home, and they also did field-work at harvest-time.^[226] Townswomen could engage in trade but often only by right of their husband, and unlike their male competitors, they were not always allowed to train apprentices.^[227] Noblewomen could inherit land in the absence of a male heir but their potential to give birth to children was regarded as their principal virtue.^[228] As women were not ordained priests, the only role open to them in the Church was that of nuns,^[229] but many popular mystics were women.^[230] Among them, the nun Hildegard of Bingen (d. 1179/80) was a prolific and highly respected author of mystical and scientific works and religious poems, who proudly stated that "no man can be made without a woman".^{[note 18][232][231]}

Trade and economy

The expansion of population, greater agricultural productivity and relative political stability laid the foundations for the medieval "Commercial Revolution" in the 11th century.^[233] People with surplus cash began investing in commodities like salt, pepper and silk at faraway markets.^[234] Rising trade brought new methods of dealing with money, and gold coinage was again minted in Europe, first in Florence and Genoa. New forms of commercial contracts emerged, allowing risk to be shared within the framework of partnerships known as commenda or compagnia.^[235] Bills of exchange also appeared, enabling easy transmission of money. As many types of coins were in circulation, money changers facilitated transactions between local and foreign merchants. Loans could also be negotiated with them which gave rise to the development of credit institutions called banks.^[236]

As new towns were developing from local commercial centres, the economic growth brought about a new wave of urbanisation. Kings and aristocrats mainly supported the process in the hope of increased tax revenues.^[237] Most urban communities received privileges acknowledging their autonomy, but few cities could get rid of all elements of royal or aristocratic control.^[238] Townspeople engaged in the same trade or profession were united in confraternities known as guilds. Typically, these associations set the rules for quality, training, and pricing, and only their members had access to the local market.^[239][240]

The Italian maritime republics such as Amalfi, Venice, Genoa, and Pisa were the first to profit from the revival of commerce in the Mediterranean.^[233] In the north, German merchants established associations known as hansas and took control of the trade routes connecting the British Islands and the Low Countries with Scandinavia and Eastern Europe.^{[note 19][242]} Great trading fairs were established and flourished in northern France, allowing Italian and German merchants to trade with each other as well as local merchants.^[243]

Economic growth provided opportunities to Jewish merchants to spread all over Europe with the local rulers' support, but most commoners regarded the non-Christian newcomers as an imminent threat to social cohesion.^[244] As the Jews could not engage in prestigious trades outside their communities, they often took despised jobs such as ragmen or tax collectors.^[245] They were especially active in moneylending for they could ignore the Christian clerics' condemnation on loan interest.^[246] The Jewish moneylenders and pawn brokers reinforced antisemitism, which led to accusations of blasphemy, blood libels, and pogroms. Church authorities' growing concerns about Jewish influence on Christian life inspired segregationist laws,^{[note 20]} and even their permanent expulsion from England in 1290.^[248]

Technology and military

Technology developed mainly through minor innovations and by the adoption of advanced technologies from Asia through Muslim mediation.^[249] Major technological advances included the first mechanical clocks and convex spectacles, and the manufacture of distilled spirits.^[250][251] Windmills were first built in Europe in the 12th century,^[250] spinning wheels appeared around 1200.^[252] Large scale construction projects advanced building technology, and increased demand for raw materials like timber, stone, and bricks.^[253] Shipbuilding improved with the use of the rib and plank method rather than the old Roman system of mortise and tenon. Other improvements to ships included the use of lateen sails and the stern-post rudder, both of which increased the speed at which ships could be sailed.^[254] The use of astrolabe and compass allowed navigation in large distance from the shores.^[255]

The development of a three-field rotation system for planting crops^{[note 21]} increased the usage of land by more than 30 per cent, with a consequent increase in production.^[256] The development of the heavy plough allowed heavier soils to be farmed more efficiently. The spread of horse collar led to the use of draught horses that required less pastures than oxen.^[257] Legumes—such as peas, beans, or lentils—were grown more widely, in addition to the cereal crops.^[258]

In military affairs, the use of infantry with specialised roles increased. Along with the still-dominant heavy cavalry, armies often included mounted and infantry crossbowmen, as well as sappers and engineers.^[259] Crossbows increased in use partly because of the increase in siege warfare.^{[note 22][199]} This led to the use of closed-face helmets, heavy body armour, as well as horse armour during the 12th and 13th centuries.^[261] Gunpowder was known in Europe by the mid-13th century.^[262]

Church life

The Romanesque Church of Maria Laach Abbey, built mainly between 1130 and 1156

In the early 11th century, papal elections were controlled by Roman aristocrats, but Emperor Henry III (r. 1039–56) broke their power and placed reform-minded clerics on the papal throne. Through popular support, they achieved the acknowledgement of their supreme jurisdiction in church affairs in many parts of Europe.^[263] In contrast, the head of the Byzantine Church Patriarch Michael I Cerularius (d. 1059) refused papal supremacy for which a papal legate excommunicated him in 1054. Eventually, after a string of mutual excommunications, this event, known as the East–West Schism, led to the separation of the Roman Catholic and Eastern Orthodox Churches.^[264][265]

Lay investiture—the appointment of clerics by secular rulers—was condemned at an assembly of bishops in Rome in 1059, and the same synod established the exclusive right of the College of Cardinals to elect the popes.^[266] Henry's son and successor Henry IV (r. 1056–1105) wanted to preserve the right to appoint his own choices as bishops within his lands but his appointments outraged Pope Gregory VII (pope 1073–85). Their quarrel developed into the Investiture Controversy, involving other powers as well because kings did not relinquish the control of appointments to bishoprics voluntarily. All conflicts ended with a compromise, in the case of the Holy Roman Emperors with the 1122 Concordat of Worms.^{[note 23][268][269]}

The High Middle Ages was a period of great religious movements.^[270] Old pilgrimage sites such as Rome, Jerusalem, and Compostela received increasing numbers of visitors, and new sites such as Monte Gargano and Bari rose to prominence.^[271] Popular movements emerged to support the implementation of the church reform but their anticlericalism sometimes led to the rejection of Catholic dogmas by the most radical groups such as the Waldensians and Cathars.^[272][273] To suppress heresies, the popes appointed special commissioners of investigation known as inquisitors.^[274] Monastic reforms continued as the Cluniac monasteries' splendid ceremonies were alien to those who preferred the simpler hermetical monasticism of early Christianity, or wanted to live the "Apostolic life" of poverty and preaching. New monastic orders were established, including the Carthusians and the Cistercians. In the 13th century mendicant orders—the Franciscans and the Dominicans—who earned their living by begging, were approved by the papacy.^[275]

Rise of state power

Europe and the Mediterranean Sea in 1190

The High Middle Ages saw the development of institutions that would dominate political life in Europe until the late 18th century, or even later.^[276] The kings' right to rule, regulate, and judge without a foreign power's intercession became widely accepted, inducing the idea of state sovereignty.^{[note 24][278]} The concept of hereditary monarchy was strengthening in parallel with the development of laws governing the inheritance of land.^[279] As female succession was recognised in most countries, the first reigning queens assumed power.^{[note 25][281]} The chancery emerged as the central office of royal government but also acted as a court of appeals.^[282] Taxation quickly developed because revenues from the royal domains could no more cover state expenditures. Initially, extraordinary taxes were levied for military purposes but by the end of the period taxes had been collected on a more regular basis.^[283] Effective taxation depended on consent which reinforced the role of representative assemblies, allowing them to exert influence on state administration.^[284][285]

The papacy, long attached to an ideology of independence from secular influence, first asserted its claim to temporal authority over the entire Christian world.^[286] The Papal Monarchy reached its apogee under the pontificate of Innocent III (pope 1198–1216).^[287] As rulers of much of central Italy and feudal overlords of some of the Catholic rulers such as the Sicilian kings, the popes were deeply involved in secular politics.^[288] Sicily and southern Italy had been seized by Norman warbands from the local Lombard, Byzantine and Muslim rulers between 1016 and 1091. Their hold of the territory was recognised by the papacy in 1059, and Roger II (r. 1105–54) united the Norman principalities into the Kingdom of Sicily.^[289]

In the Holy Roman Empire, the Ottonians were replaced by the Salians in 1024. They protected the lesser nobility to reduce ducal power, and seized Burgundy before clashing with the papacy under Henry IV.^[290] After a short interval between 1125 and 1137, the Hohenstaufens succeeded the Salians. Their recurring conflicts with the papacy allowed the northern Italian cities and the German princes to extort considerable concessions from them. In 1183, Frederick I Barbarossa (r. 1155–90) sanctioned the right of the Lombard cities to elect their leaders; the princes' autonomy was recognised during the reign of his grandson Frederick II (r. 1220–50).^[291] Frederick was famed for his erudition and unconventional life style^{[note 26]} but his efforts to rule Italy eventually led to the fall of his dynasty. In Germany, a period of interregnum, or rather civil war began, whereas Sicily—Frederick's maternal inheritance—was seized by an ambitious French prince Charles I of Anjou (r. 1266–85).^[293] During the German civil war, the right of seven prince-electors to elect the king was reaffirmed. Rudolf of Habsburg (r. 1273–91), the first king to be elected after the interregnum, realised that he was unable to control the whole empire. He granted Austria to his sons, thus establishing the basis for the Habsburgs' future dominance in Central Europe.^[294][295] After his death, the people of three Alpine communities formed the Swiss Confederacy to defend their judicial autonomy against the Habsburgs.^[296][297]

The French monarchy slowly began to expand its authority over the nobility.^[298] The kings faced a powerful rival in the Dukes of Normandy, who in 1066 under William the Conqueror (r. 1035–87) conquered England. This cross-Channel empire further expanded when Henry II (r. 1154–89) from the Angevin dynasty ascended the throne, as he had seized large areas of France through inheritance and marriage.^{[note 27]} Under his son Richard I (r. 1189–99), the Angevin Empire remained intact, but Richard's brother John (r. 1199–1216) lost the northern French possessions to the French king Philip II Augustus (r. 1180–1223).^[300] This led to dissension among the English nobility, while John's financial exactions to pay for his unsuccessful attempts to regain Normandy led in 1215 to Magna Carta, a charter that confirmed the rights and privileges of free men in England.^[301] In France, Philip Augustus's son Louis VIII (r. 1223–26) distributed large portions of his father's conquests among his younger sons as appanages—virtually independent provinces—to facilitate their administration.^[302] His son Louis IX (r. 1226–70) improved local administration by appointing inspectors known as enquêteurs to oversee the royal officials' conduct. The royal court at Paris began hearing litigants in regular sessions almost all over the year.^[303]

The Iberian Christian states began to push back against the Islamic powers in the south, a period known as the Reconquista.^[304] After numerous divisions and reunifications of the Christian states, the Christian north had coalesced into the four kingdoms of Castile, Aragon, Navarre, and Portugal by 1230.^[305][306] Aragon emerged as a naval power, conquering the Balearic Island from the Muslims, Sicily from the Italian Angevins, and Sardinia from the Genoese.^[307][308] Southern Iberia remained under the control of Islamic states, initially under the Caliphate of Córdoba, which broke up in 1031 into a shifting number of petty states known as taifas. Although the Almoravids and the Almohads, two dynasties from the Maghreb, established centralised rule over Southern Iberia in the 1110s and 1170s respectively, their empires quickly disintegrated, allowing further expansion of the Christian kingdoms.^[309] The Catholic Scandinavian states also expanded: the Norwegian kings assumed control of the Norse colonies in Iceland and Greenland, Denmark seized parts of Estonia, and the Swedes conquered Finland.^[310]

In the east, Kievan Rus' fell apart into independent principalities. Among them, the northern Vladimir-Suzdal emerged as the dominant power after Suzdalian troops sacked Kyiv in 1169.^[311] Poland also disintegrated into autonomous duchies in 1138, enabling the Czech kings to expand in the prosperous Duchy of Silesia in the late 13th century.^[312] The kings of Hungary seized Croatia but respected the liberties of the native aristocracy. They claimed (but only periodically achieved) suzerainty over other lands and peoples such as Dalmatia, Bosnia, and the nomadic Cumans.^[313] The Cumans supported the Bulgarians and Vlachs during their anti-Byzantine revolt that led to the restoration of Bulgaria in the late 12th century.^[314] To the west of Bulgaria, Serbia gained independence.^[315]

With the rise of the Mongol Empire in the Eurasian steppes under Genghis Khan (r. 1206–27), a new expansionist power reached Europe's eastern borderlands.^[316] Between 1236 and 1242, the Mongols conquered Volga Bulgaria, shattered the Rus' principalities, and laid waste to large regions in Poland, Hungary, Croatia, Serbia and Bulgaria. Their commander-in-chief Batu Khan (r. 1241–56)—a grandson of Genghis Khan—set up his capital at Sarai on the Volga, establishing the Golden Horde, a Mongol state nominally under the distant Great Khan's authority. The Mongols extracted heavy tribute from the Rus' principalities, and the Rus' princes had to ingratiate themselves with the Mongol khans for economic and political concessions.^{[note 28][318]} Under Mongol pressure, the Anatolian Seljuk Sultanate disintegrated into small but often aggressive Turkic lordships, such as the one ruled by the Ottoman clan on the Byzantine border.^[319] The Mongol conquest was followed by a peaceful period in Eastern Europe which facilitated the development of direct trade contacts between Europe and China through newly established Genoese colonies in the Black Sea region.^[320] The new land and sea routes to the Far East were famously described in The Travels of Marco Polo written by one of the traders, Marco Polo (d. 1324).^[233]

Crusades

Clashes with secular powers accelerated the militarization of the papacy. Pope Urban II (pope 1088–99) proclaimed the First Crusade at the Council of Clermont in response to a Byzantine appeal for military aid against the Seljuk Turks. He declared the liberation of Jerusalem as its ultimate goal, and offered indulgence—the remission of sins—to all who took part.^[321] Tens of thousands of fanatics, mainly common people, formed loosely organised bands to march to the east. They lived off looting, and attacked the Jewish communities. Antisemitic pogroms were especially violent in the Rhineland. Few of them reached Asia Minor, and those who succeeded were annihilated by the Turks.^[322] The official crusade departed in 1096 under the command of prominent aristocrats like Godfrey of Bouillon (d. 1100), and Raymond of Saint-Gilles (d. 1105). They defeated the Turks in two major battles at Dorylaeum and Antioch, allowing the Byzantines to recover western Asia Minor. The westerners consolidated their conquests into crusader states in northern Syria and Palestine, but their security depended on external military assistance which led to further crusades.^[323] Muslim resistance was raised by ambitious warlords, like Saladin (d. 1193) who captured Jerusalem in 1187.^[324] New crusades prolonged the crusader states' existence for another century, until the crusaders' last strongholds fell to the Mamluks of Egypt in 1291.^[325]

The papacy used the crusading ideology against its opponents and non-Catholic groups in other theaters of war as well.^[326] The Iberian crusades became fused with the Reconquista and reduced Al-Andalus to the Emirate of Granada by 1248. The northern German and Scandinavian rulers' expansion against the neighbouring pagan tribes developed into the Northern Crusades bringing the forced assimilation of numerous Slavic, Baltic and Finnic peoples into the culture of Catholic Europe.^[327] The Fourth Crusade was diverted from the Holy Land to Constantinople, and captured the city in 1204, setting up a Latin Empire in the east. Michael VIII Palaiologos (r. 1259–82), the ruler of a Byzantine rump state in Asia Minor^{[note 29]} recaptured the city in 1261, but parts of Greece remained under the westerners' rule.^[328][329] The Albigensian Crusades against the Cathars of Occitania provided the opportunity for the French monarchy to expand into the region.^[330]

With its specific ceremonies and institutions, the crusading movement became a featuring element of medieval life.^{[note 30]} Often extraordinary taxes were levied to finance the crusades, and from 1213 a crusader oath could be fulfilled through a cash payment which gave rise to the sale of plenary indulgences by Church authorities.^[332] The crusades brought about the fusion of monastic life with military service within the framework of a new type of monastic order, the military orders. The establishment of the Knights Templar set the precedent, inspiring the militarisation of charitable associations, like the Hospitallers and the Teutonic Knights, and the founding of new orders of warrior monks, like the Order of Calatrava and the Livonian Brothers of the Sword.^[333][334] Although established in the crusader states, the Teutonic Order focused much of its activity in the Baltic where they founded their own state in 1226.^[335]

Intellectual life

Cathedral chapters were expected to operate a school from the late 11th century, and the more lenient cathedral schools quickly marginalised the traditional monastic schools. Schools reaching the highest level of mastery within the disciplines they taught received the rank of studium generale, or university from the pope or the Holy Roman Emperor.^[336][337] The new institutions of education encouraged scholarly discussions.^[338] Debates between the realists and the nominalists over the concept of "universals" were especially heated. Philosophical discourse was stimulated by the rediscovery of Aristotle and his emphasis on empiricism and rationalism. Scholars such as Peter Abelard (d. 1142) and Peter Lombard (d. 1164) introduced Aristotelian logic into theology.^[339] Scholasticism, the new method of intellectual discourse and pedagogy, required the study of authoritative texts, notably the Vulgate and patristic literature, but references to them could no more override rational argumentation.^[340] Scholastic academics summarised their and other authors' views on specific subjects in comprehensive sentence collections known as summae, including the Summa Theologica by Thomas Aquinas (d. 1274).^[341]

Chivalry and the ethos of courtly love developed in royal and noble courts. This culture was expressed in the vernacular languages rather than Latin, and comprised poems, stories, legends, and popular songs. Often the stories were written down in the chansons de geste, or "songs of great deeds", glorifying their male heroes' often brutal acts, such as The Song of Roland, and The Poem of the Cid. In contrast, chivalric romance praised chaste love, while eroticism was mainly present in poems composed by troubadours.^[342][343] Chivalric literature took inspiration from classical mythology, and also from the Celtic legends of the Arthurian cycle collected by Geoffrey of Monmouth (d. c. 1155).^[344] Further featuring literary genres include spiritual autobiographies, chronicles, philosophical poems, and hymns.^{[note 31][345]}

The discovery of a copy of the Corpus Juris Civilis in the 11th century paved the way for the systematic study of Roman law at Bologna. This led to the recording and standardisation of legal codes throughout Western Europe. Around 1140, the monk Gratian (fl. 12th century), a teacher at Bologna, wrote what became the standard text of ecclesiastical law, or canon law—the Decretum Gratiani.^[346] Among the results of the Greek and Islamic influence on this period in European history was the replacement of Roman numerals with the decimal positional number system and the invention of algebra, which allowed more advanced mathematics. Astronomy benefited from the translation of Ptolemy's Almagest from Greek into Latin in the late 12th century. Medicine was also studied, especially in southern Italy, where Islamic medicine influenced the school at Salerno.^[347]

Architecture, art, and music

León Cathedral, an example of Rayonnant Gothic, completed in three phases during the 13th–15th centuries

Encastellation continued, as more and more stone fortresses were built in regions where central authority was weak.^[348] Many of them were motte-and-bailey structures, but Bergfriede, or tower castles, were preferred in Central Europe,^{[note 32]} and the competing urban families built tall towers in Italian cities and towns.^{[note 33][351]} The great pilgrimages entailed the construction of large churches along pilgrimage roads.^{[note 34]} This led to the development of stone architecture that bears some resemblance to classical Roman building design, hence known as Romanasque. Romanesque buildings have massive stone walls, decorated with sculpture in relief, and are typically covered by barrel, groin or rib vaults.^[353] Romanesque has various regional variants: in Provence, Corinthian columns betray the direct influence of the local Roman monuments; in Tuscany, stone arches were used as ornamental elements; and in Norway, dragon heads decorated the exterior of stave churches.^[354] Traditional Byzantine religious architecture remained dominant in the Balkans although some Serbian churches display Romanesque influence.^{[note 35][356]}

Romanesque art, especially metalwork, was at its most sophisticated in Mosan art, in which distinct artistic personalities including Nicholas of Verdun (d. 1205) become apparent, and an almost classical style is seen in works such as a font at Liège.^[357] Few wall-paintings survive although references to images abound in written sources in the 11th–12th centuries. The employment of itinerant artists, and the use of sketches made of murals facilitated the transmission of artistic motifs over large territory.^{[note 36]} Embroidery flourished as the churches and castles were decorated by tapestries, and clerical vestments were adorned by needlework images.^[359]

Structural innovations introduced the development of the Gothic style from Romanesque. These included pointed arches for the reduction of lateral thrust, flying buttresses to reinforce the walls, and rib vaults to minimise their static importance. The new solutions allowed the extensive use of large stained glass windows.^[360] The Gothic architecture emerged as a combination of all these during the reconstruction of the Saint-Denis Abbey near Paris under Abbot Suger (d. 1151).^[361][362] The new style quickly spread and dominated religious architecture in much of Catholic Europe till the end of the Middle Ages.^{[note 37][365]}

The practice of manuscript illumination gradually passed from monasteries to lay workshops, and the book of hours developed as a form of devotional book for lay-people.^[366] Metalwork continued to be the most prestigious form of art, with Limoges enamel a popular and relatively affordable option.^[367] In Italy the innovations of Cimabue and Duccio, followed by the Trecento master Giotto (d. 1337), greatly increased the sophistication and status of panel painting and fresco.^[368] Increasing prosperity during the 12th century resulted in greater production of secular art; many carved ivory objects such as gaming pieces, combs, and small religious figures have survived.^[369]

Society and economy

Average annual temperature was declining from around 1200, introducing the gradual transition from the Medieval Warm Period to the Little Ice Age. Climate anomalies caused agricultural crises, culminating in the Great Famine of 1315–17.^[370] As the starving peasants slaughtered their draft animals, those who survived had to make extraordinary efforts to revive farming. The previously profitable monoculture aggravated the situation, as unseasonable weather could completely ruin a harvest season.^[371]

These troubles were followed in 1346 by the Black Death, a pandemic that spread throughout Europe, killing about one-third of the population in four years. As plague continued to strike Europe regularly, the total population halved between 1346 and 1400. Towns were especially hard-hit because of their crowded conditions.^{[note 38][373]} The trauma of the plague led to savage pogroms against the Jews, and the self-mortification of the flagellants.^[374] The rapid and extremely high mortality destroyed economy and trade, and the recovery was slow. The peasants who survived the pandemic paid lower rents to the landlords but demand for agricultural products declined, and the lower prices barely covered their costs. Urban workers received higher salaries but they were heavily taxed. Occasionally, the governments tried to fix rural rents at a high level, or to keep urban salaries low, which provoked popular uprisings across Europe, including the Jacquerie in France, the Peasants' Revolt in England, and the Ciompi Revolt in Florence.^[375]

Labor services the peasants owed for their land tenure were often changed into cash rents, providing the landlords with a stable source of income. Landlords joined to extort privileges from their governments but royal administration also started to protect the interests of the poor.^[376] From the early 14th century, serfdom was officially abolished in many places,^[377] although in other regions, mainly in Central and Eastern Europe, it was imposed on tenants who had previously been free.^[378] Non-clergy became increasingly literate, and urban populations began to imitate the nobility's interest in chivalry.^[379] The rise of banking continued, fuelled partly by the crossborder movement of church revenues, facilated by large merchant houses. These also loaned money to warring royalty, at great risk, as some were bankrupted when kings defaulted on their loans.^{[note 39][381]}

Private feuds were almost permanent in politically fragmented regions, such as Westphalia in Germany, and the Pyrenean frontier of France, and regional conflicts often escalated into full-scale warfare.^[382] Reissen, or crusading tours in the Baltic region, became a fashionable form of warring for Catholic aristocrats.^[383] Conflicts between ethnic groups became polarised, and local statutes were issued to prohibit intermarriages and limit membership in guilds along ethnic lines.^{[note 40][385]} The Jewish communities were permanently expelled from France, and at least provisionally from most German cities and principalities. In contrast, the Hungarian and Polish rulers encouraged the Jewish moneylenders' immigration.^[386] Massive pogroms led to the mass conversion of Spanish (or Sephardic) Jewry in 1391. As the "New Christians" were suspected of heresy, the Spanish Inquisition was established to inspect their faith. The Jews who refused to convert were exiled from Spain in 1492, and from Portugal in 1497. Most Spanish Jews left for the Ottoman Empire.^[387][388]

State resurgence

Although the growth of central governments continued, still more than 500 autonomous polities existed at the end of the period.^[389] Taxation quickly expanded which contributed to the development of self-conscious communities of taxpayers, eager to protect their common interests both at central and local levels.^[390] Successful dynasties reigned over several states mainly in close cooperation with local elites but could not freely redistribute resources among their realms.^{[note 41][391]}

In Germany, the elected emperors were no more than supreme arbitrators, although they had a significant power base in their hereditary lands.^{[note 42][393][394]} The emperors' authority was even more limited in Italy where Florence, Milan, and Venice exploited the power vacuum to expand.^[395] The centuries-old rivalry between England and France developed into the Hundred Years' War when Edward III (r. 1327–77) laid claim to the French throne in 1337.^[396][397] The English won the battles of Crécy and Poitiers, captured the city of Calais, and won control of an enlarged Gascony by 1360. French aristocrats' feuds escalated into a civil war, allowing Henry V of England (r. 1413–22) to seize much of France.^[398][373] The unconquered French regions put up a strong resistance, boosted by the visions of a peasant girl Joan of Arc (d. 1431), and Charles VII of France (r. 1422–61) expelled the English from the country except for Calais by 1453.^[399][400] England went on to suffer a long civil war known as the Wars of the Roses, which ended after Richard III (r. 1483–85) died fighting at Bosworth, and his opponent Henry Tudor consolidated power as Henry VII (r. 1485–1509).^[401] The wars mainly prevented the English to expand in the British Isles, but royal power remained weak in Scotland, and much of Ireland was ruled by feuding local lords.^[402][403]

Succession troubles were not uncommon in the Iberian kingdoms, as intermarriages between the royal houses created conflicting claims to the thrones, and royal bastards could successfully claim their father's inheritance.^[404][405] Portugal opened a new theater of anti-Muslim warfare in Morocco by seizing Ceuta in 1415.^[406] Aragon and Castile were riven by conflicts between magnate factions or over the limits of royal government but the Castilian Isabella I (r. 1474–1504) and her Aragonese husband Ferdinand II (r. 1479–1516) reinforced royal power.^[407] To enhance national unity, they invaded Granada, completing the Reconquista in 1492.^[408]

The idea of elective kingship revived in the Scandinavian and Central European monarchies for various reasons, including the aristocrats' aversion to foreign influence.^[409][410] Royal power was restored in Poland early in the 14th century, in a period when the Teutonic Knights' expansion intensified. The Knights primarily targeted Lithuania, a loose confederation of mainly pagan Lithuanian chieftains and Orthodox Rus' principalities. The common enemy brought about a lasting Polish–Lithuanian union, sealed by the marriage of the Lithuanian grand duke Jogaila (r. 1377–1434) with the Polish queen Jadwiga (r. 1384–99),^{[note 43]} and the Lithuanians' conversion to Catholicism.^[412][413] In Scandinavia, Margaret I of Denmark (r. 1387–1412) consolidated Denmark, Norway, and Sweden in the Union of Kalmar in 1397 but only the Danish–Norwegian union proved lasting.^{[note 44][416]}

Polish, Hungarian, and Lithuanian invasions, and succession crises undermined the Golden Horde's power in the 14th century.^[417][418] The princes of Muscovy, previously the Mongol khans' favorites, began annexing the Rus' principalities often in competition with Lithuania. Under Grand Prince Ivan III (r. 1462–1505), the conquest of the great trading cities of Novgorod and Tver completed Muscovy's dominance in the northeast.^[419][420] In southeastern Europe, two small Vlach principalities emerged, Wallachia and Moldavia; their rulers mainly accepted the suzerainty of the Hungarian or Polish kings.^[421]

Collapse of Byzantium and rise of the Ottomans

Facing financial crises and threats from the west, the restored Byzantine Empire was unable to prevent the Turks' expansion in Anatolia. Revolts by Catalan mercenaries and recurring civil wars further weakened the empire,^{[note 45]} allowing the Ottoman Turks to establish a strategic bridgehead at Gallipoli in Europe in 1354.^[423][424] Within a century, the Ottomans reduced the competing kingdoms, principalities and lordships to tributary states in southeastern Europe.^[425][426] International coalitions formed against the Ottomans, such as the Crusades of Nicopolis (1396) and Varna (1444), were unable to stop their advance.^[427] The last Byzantine emperor Constantine XI (r. 1449–53) died fighting during the conquest of Constantinople by Sultan Mehmed II (r. 1451–81).^[428] Talented military commanders could repel individual Ottoman attacks^{[note 46]} but by the end of the century the Ottomans conquered all Balkan states: Bulgaria was fully occupied in 1396, Byzantine Greece in 1460, Serbia in 1459, Bosnia in 1463, and the Ottomans broke all Albanian lords' resistance by 1488.^[430] The Ottoman sultans ruled a highly centralised state, often appointing slaves to the highest offices. The sultans avoided civil wars by murdering their brothers from the late 15th century.^[431]

Controversy within the Church

Disputes within the leadership of the Church led to the Avignon Papacy of 1309–76,^[432] and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states.^[433] Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year, the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417, the council elected Martin V (pope 1417–31) as pope.^[434]

Besides the schism, the Western Church was riven by theological controversies. John Wycliffe (d. 1384), an English theologian, was condemned as a heretic in 1415 for teaching that the laity should have access to the text of the Bible as well as for holding views on the Eucharist that were contrary to Church doctrine.^[435] Wycliffe's teachings influenced two of the major heretical movements of the later Middle Ages: Lollardy in England and Hussitism in Bohemia.^[436] The Bohemian movement initiated with the teaching of Jan Hus, who was burned at the stake in 1415. The Hussite Church, although the target of a crusade, survived beyond the Middle Ages.^[437] Other heresies were manufactured, such as the accusations against the wealthy Knights Templar that resulted in their suppression in 1312.^[438][439]

The laity continued the practices of pilgrimages, veneration of relics, and belief in the power of the devil. Mystics such as Meister Eckhart (d. 1327) and Thomas à Kempis (d. 1471) wrote works that taught the laity to focus on their inner spiritual life, which laid the groundwork for the Protestant Reformation. Besides mysticism, belief in witches and witchcraft became widespread, and by the late 15th century, the Church had begun to lend credence to populist fears of witchcraft.^[440]

Scholars, intellectuals, and exploration

During the Later Middle Ages, theologians such as John Duns Scotus (d. 1308) and William of Ockham (d. c. 1348) led a reaction against intellectualist scholasticism, objecting to the application of reason to faith. Their efforts undermined the prevailing Platonic idea of universals. Ockham's insistence that reason operates independently of faith allowed science to be separated from theology and philosophy.^[441] Legal studies were marked by the steady advance of Roman law into areas of jurisprudence previously governed by customary law. The lone exception to this trend was in England, where the common law remained pre-eminent. Other countries codified their laws; legal codes were promulgated in Castile, Poland, and Lithuania.^[442]

Clerics studying astronomy and geometry, French, early 15th century

Education remained mostly focused on the training of future clergy. The basic learning of the letters and numbers remained the province of the family or a village priest, but the secondary subjects of the trivium—grammar, rhetoric, logic—were studied in cathedral schools or in schools provided by cities. Universities spread throughout Europe in the 14th and 15th centuries. Lay literacy rates rose, but were still low; one estimate gave a literacy rate of ten per cent of males and one per cent of females in 1500.^[443]

The publication of vernacular literature increased, with Dante (d. 1321), Petrarch and Boccaccio in 14th-century Italy, Geoffrey Chaucer (d. 1400) and William Langland (d. c. 1386) in England, and François Villon (d. 1464) and Christine de Pizan (d. c. 1430) in France. Much literature remained religious in character, and although a great deal of it continued to be written in Latin, a new demand developed for saints' lives and other devotional tracts in the vernacular languages.^[442] This was fed by the growth of the Devotio Moderna movement, most prominently in the formation of the Brethren of the Common Life.^[444] Theatre also developed in the guise of miracle plays put on by the Church.^[442] At the end of the period, the development of the printing press in about 1450 led to the establishment of publishing houses throughout Europe by 1500.^[445]

In the early 15th century, the countries of the Iberian Peninsula began to sponsor exploration beyond the boundaries of Europe. Prince Henry the Navigator of Portugal (d. 1460) sent expeditions that discovered the Canary Islands, the Azores, and Cape Verde during his lifetime. After his death, exploration continued; Bartolomeu Dias (d. 1500) went around the Cape of Good Hope in 1486, and Vasco da Gama (d. 1524) sailed around Africa to India in 1498.^[446] The combined Spanish monarchies of Castile and Aragon sponsored the voyage of exploration by Christopher Columbus (d. 1506) in 1492 that led to his discovery of the Americas.^[447] The English crown under Henry VII sponsored the voyage of John Cabot (d. 1498) in 1497, which landed on Cape Breton Island.^[448]

Technological and military developments

One of the major developments in the military sphere during the Late Middle Ages was the increased use of infantry and light cavalry.^[449] The English also employed longbowmen, but other countries were unable to create similar forces with the same success.^[449] Armour continued to advance, spurred by the increasing power of crossbows, and plate armour was developed to protect soldiers from crossbows as well as the handheld guns that were developed.^[450] Pole arms reached new prominence with the development of the Flemish and Swiss infantry armed with pikes and other long spears.^[451] The cannon appeared on the battlefield at Crécy in 1346.^[452]

In agriculture, the increased usage of sheep with long-fibred wool allowed a stronger thread to be spun. In addition, the spinning wheel replaced the traditional distaff, tripling production.^{[252][note 47]} A less technological refinement that still greatly affected daily life was the use of buttons as closures for garments.^[454] Windmills were refined with the creation of the tower mill, allowing the upper part of the windmill to be spun around to face the direction from which the wind was blowing.^[455] The blast furnace appeared around 1350 in Sweden, increasing the quantity of iron produced and improving its quality.^[456] The first patent law in 1447 in Venice protected the rights of inventors to their inventions.^[457]

Art and architecture

The Late Middle Ages in Europe as a whole correspond to the Trecento and Early Renaissance cultural periods in Italy. Northern Europe and Spain continued to use Gothic styles, which became increasingly elaborate in the 15th century, until almost the end of the period. International Gothic was a courtly style that reached much of Europe in the decades around 1400, producing masterpieces such as the Très Riches Heures du Duc de Berry.^[458] All over Europe, secular art continued to increase in quantity and quality, and in the 15th century, the mercantile classes of Italy and Flanders became important patrons, commissioning small portraits as well as a growing range of luxury items such as jewellery, ivory caskets, cassone chests, and maiolica pottery. Although royalty owned huge collections of plate, little survives except for the Royal Gold Cup.^[459] Italian silk manufacture developed, so that Western churches and elites no longer needed to rely on imports from Byzantium or the Islamic world. In France and Flanders tapestry weaving of sets like The Lady and the Unicorn became a major luxury industry.^[460]

The large external sculptural schemes of Early Gothic churches gave way to more sculpture inside the building, as tombs became more elaborate and other features such as pulpits were sometimes lavishly carved, as in the Pulpit by Giovanni Pisano in Sant'Andrea. Painted or carved wooden relief altarpieces became common, especially as churches created many side-chapels. Early Netherlandish paintings by artists such as Jan van Eyck (d. 1441) and Rogier van der Weyden (d. 1464) rivalled that of Italy, as did northern illuminated manuscripts, which in the 15th century began to be collected on a large scale by secular elites, who also commissioned secular books, especially histories. From about 1450, printed books rapidly became popular, though still expensive. There were around 30,000 different editions of incunabula, or works printed before 1500,^[461] by which time illuminated manuscripts were commissioned only by royalty and a few others. Very small woodcuts, nearly all religious, were affordable even by peasants in parts of Northern Europe from the middle of the 15th century. More expensive engravings supplied a wealthier market with a variety of images.^[462]
