Ancient

Comb-patterned earthenware and stone tools from the early Neolithic period were excavated from shell mounds in Jangwol-ri, Angok-myeon and Panori in Anak-eup, confirming that Anak had been the home of people from an early age.In addition, two dwellings from the Bronze Age were excavated in Baksa-ri, Daewon-myeon, and relics from the Bronze Age such as dolmens, stone swords, stone knives, half-moon swords, stone axes, and stone coins were found here and there.In Baksa-ri, many artifacts from the early Iron Age have been excavated, and the culture has been passed down from the prehistoric age to the historical age. It was the territory of Goguryeo during the Three Kingdoms period, and after the unification of the Three Kingdoms, it was incorporated into the territory of Silla and organized into Yangak County(楊岳郡) in 757 (King Gyeongdeok 16).^[3] The ancient tombs No. 1, 2, and 3 of Anak in Sangsan-ri, Daewon-myeon and Yusun-ri, Yongsun-myeon, which are famous for their murals, represent the level of culture of the Goguryeo period in the 4th century. In particular, Tomb No. 3 has a wall of 81 m² and a ceiling of 58 m² filled with various figures and genre paintings, depicting customs of Goguryeo as well as music and house structure.

Koryo dynasty

Wang Geon's powers cooperated with Gung Ye to be incorporated into Taebong's territory around 905, and it is presumed that it was around this time that the name of the place was changed to Anak. In 1018 (9th year of King Hyeonjong), it became a subcounty of Pungju, and in 1106 (1st year of King Yejong), as the number of wanderers without a fixed residence increased, Gammu was appointed to calm down the residents.

In 1259 (Gojong 46), it was invaded by the Mongol army and surrendered.In 1270, it became part of Dongnyeong prefectures, but was restored to its original subdivision after 8 years. Even after the mid-14th century, it was damaged several times due to invasions by the Red Turbans and Japanese pirates. In 1348 (the 4th year of King Chungmok's reign),as the region was reported as the home town of the wife of Munhachanseongsa, Hwangsun (黃順), the region was promoted to county, and was the post of Jigunsa (知郡事) was appointed.^[3]

Joseon dynasty

It was confirmed as a county in 1413 (13th year of King Taejong) and the head of the county was appointed. According to the geography of the 『Veritable records of King Sejong』, the number of households in the mid-15th century was relatively small, with 991 households and 3,703 people. Even in the early Joseon Dynasty, the life of the residents did not expand significantly, and in the mid-16th century, it became the main activity base of Im Kkeokjeong, who was active around Mount Kuwolsan.

Administratively, in addition to the period from 1589 (the 22nd year of King Seonjo) to 1608, it went through several ups and downs of being demoted to a prefecture. During the Japanese Invasion of Korea in 1592, when the Japanese army stationed in Kuwolsan was attacked by the Ming Dynasty army and retreated, he raised a righteous army and attacked it, making a contribution.

Even in the 17th century, many bandits gathered in Mt. Kuwol, so in 1684 (the 10th year of King Sukjong's reign), Jungyeongjang (中營將), who had been stationed in Sincheon, was moved to Anak, and Junggun (中軍) was assigned to take on the duties of Toposa. However, since then, agriculture has greatly developed, centering on rice and cotton cultivation, reclamation projects have been actively carried out, and trade with the Pyeongan Province has increased.^[3]

In 1759 (35th year of King Yeongjo), all of them were organized into 18 rooms and 80 ri, indicating that the military force had grown significantly, and the number of households was 14,509 households and 51,247, second only to Haeju in the province. The population in 1828 (Sunjo 28) was 53,546.^[3]

Late Joseon period and colonial period

In 1894, Donghak troops of this county gathered together at Paeyeopsa Temple (貝葉寺) along with Donghak troops from Haeju and Sincheon, but collapsed due to an attack by the same Donghak army, Lee Dong-yeop (李東燁) unit.

This revolutionary spirit was actively accepted through Catholicism and Protestantism, while educational and cultural organizations such as the Myunhakhoe actively accepted Shinmunmyeong. In January 1911, Japan was hit again by manipulating the so-called 'Anak Incident'.^[3]

At that time, about 160 people, including Kim Gu, Kim Hong-ryang, Kim Yong-je, and Choi Myeong-sik, were imprisoned, which was a precursor to the 105 Persons Incident that occurred in the fall of that year. Due to Kim Gu's position as a teacher at Yangsan School, many figures from the region, including Kim Gi-hyung, Na Tae-seop, Oh Myeon-shik, and Choi Ik-hyeong, were active in the Provisional Government. In 1935, 1 eup, 8 myeons, and 113 villages were organized, and in 1942, there were 104,572 households in 19,030 households.^[3]

After liberation

In 1952, when administrative districts were reorganized, Sancheon-myeon, Yongjin-myeon, and Nowol-myeon of Sinchon County, Anak-eup of Anak County, and Yongsun-myeon was reorganized into Daewon-myeon and Munsan-myeon. In 1954, Hwanghae Province was divided into North and South, leading the region to become part of South Hwanghae Province.^[3]
