Accession

Selyamet had arranged for Janibek to follow him, even though Mehmed (later Mehmed III Giray), being the son of a khan, had a better claim. When he died the brothers Mehmed and Shahin Giray invaded and made themselves khan and kalga. Jannibek fled to Kaffa, and appealed to the Turks. The Turks sent eight galleys with janissaries and Mehmed and Shahin fled to the steppes. Hearing that the Turks were leaving the brothers invaded again and were defeated by the remaining Turks.

Zaporozhian and Budjak raids

During the Time of Troubles many Zaporozhian Cossacks had been drawn northward, but when things settled down they turned southward in search of loot. Each year some 30 to 100 Cossack boats left the mouth of the Dnieper to raid the Crimean and Turkish coasts. In 1612 they raided Gozlev and next year attacked Crimea twice. In 1616 they burned Kaffa and later plundered Trazon and raided the Bosphorus coast. The Turks burned their camps on the Dnieper but could not catch their ships. (?^[2]) Around 1620 king Sigismund III Vasa tried to control the Zaporozhians by paying them (Registered Cossacks), but there was not enough money for this to work.

At this time the Budjak Horde under Khan Temir was unusually active in raiding Poland. When Shahin Giray was driven out of Crimea in 1610 he joined the Budjak raiders. He brought his followers so much loot that he became more popular than the inactive Janibek. Janibek sent two armies against him. In 1614 the Turks drove him out. The Budjaks later fought for the Turks at Khotin and elsewhere.

The Poles had little control over their Zaporozhian subjects and the Turks had little control over the Budjak Horde. Each power used their subject-raiders to put pressure on the other.

Fighting the Persians

Around 1616 ^[3] the sultan ordered Jannibek to fight the Persians (Ottoman–Safavid War (1603–1618)). During his absence his brother Devlet was in charge of Crimea. Crossing north of the Caucasus he became involved with his son-in-law, Ish-Terek, Bey of the Great Nogai Horde. Ish-Terek had declared himself a direct subject of the sultan. Previously the Nogais had recognized the supremacy of the Crimeans just as the Crimeans recognized the supremacy of the Turks. He also proposed a Nogai-Turkish attack of Astrakhan, which the Turks refused. When Ish-Terek claimed to be the khan's equal, Jannibeg moved against him and Ish-Terek fled for protection of the Russian governor of Astrakhan. Instead of following him, the khan attacked his Kabardian allies. When he then tried to cross the passes of Dagestan to Persia he found them blocked by the Nogais, Kabardians and Kumyks whom he had offended. Seeing no way to break through, the khan returned to Crimea in shame.

The following year the troops were transported by ship across the Black Sea from Kaffa to Trabzon and then marched east across the Trans-Causasus. The result was a disaster for the Turco-Crimean side. The begs of the Shirin and Mansur clans were killed, the khan's advisor Bek-Ata was captured and the Crimeans lost at least 8000 men. The Turks blamed the Crimeans and the Crimeans blamed Shahin Giray who was helping the Persians.

In late 1617 or early 1618 Jannibek went to Istanbul to explain himself. In the spring of 1619 he returned to Crimea

Fighting the Poles

In 1615 Janibek led a very successful raid into Podolia and Galicia. He claimed it was in retaliation for the Zaporozhian raids.

In 1617, while Jannibek was fighting the Persians, the Sultan ordered Janibek's brother Devlet to fight the Poles. Devlet tried to hold his troops back since he feared an attack from Shahin Giray. Many of his men slipped away to Poland, hoping for loot. It is possible that Shahin could have captured Crimea at this time if he had known about the shortage of troops.^[4] The Sultan planned a joint Turkish-Crimean-Budjak attack to force the Poles to rein in the Zaporozhians. Stanisław Żółkiewski brought up an army. The sides chose not to fight and made a compromise in which they agreed to limit the raids of their subjects (Peace of Busza). These promises had little effect since they had little control over the freebooters whom they claimed to rule. (?^[5])

Around 1620 Moldavia revolted against the Turks (Polish–Ottoman War (1620–21)). Polish crown hetman Zolkievski entered Moldavia in September 1620. The Turks called in their Crimean and Budjak vassals. Jannibek stayed in Crimea for fear of Shahin and sent his brother Devlet. Devlet quarreled with Khan Temir. At the Battle of Cecora (1620) the Poles were at defeated and began to retreat. They were surrounded and defeated by Khan Temir. The Budjaks began a massive looting of Polish territory and were joined by the Crimeans.

Encouraged by this success, the Turks began the Battle of Khotyn (1621) in September 1621, aided by Janibek in person. The fighting lasted four weeks and was not decisive, but the Turks lost so many men that it discouraged further advance. The Turks were pleased with Khan Temir and displeased with Jannibek, who seemed reluctant to fight. Jannibek went back to Crimea but most of his men abandoned him and stayed to loot. The Turks began to consider removing him.

Turkish problems and deposition

His first Persian campaign was an abject failure. After his second Persian failure, in late 1617 or early 1618 Janibek went to Istanbul to explain himself. Here he was caught up in the confusion following the death of Ahmed I. This confusion and Janibek's absence led Shahin Giray to attempt an invasion of Crimea. When things settled down Janibek retained precarious Turkish support and returned to Crimea (spring 1619). In the 1620 Cecora campaign Devlet proved himself a better fighter than his brother. In the 1621 Khotyn campaign Janibek was reluctant to fight a pitched battle and wanted to spread his men out to loot. After the battle his men were turned loose to loot while Janibek went back to Crimea. Many of his followers abandoned him and joined the looters. Osman II had a low opinion of Janibek but left him on the throne. In 1622 Osman was killed by his janissaries. In February 1623 Mere Husein Pasha, a friend of Mehmed, became vizier. Mehmed was released from prison, made khan as Mehmed III and arrived in Kaffa on 19 May 1623. Janibek did not resist but went to istanbul where he was granted an estate at Edirne.
