Immigration and settlement of Gaya and Wa people in Hoseo Region of Hanseong period of Baekje

This study set out to to make an approach to the immigration and settlement of Gaya and Wa(倭) people in Hoseo region of Hanseong period of Baekje, examining regions and periods of archaeological artifacts related to immigration. The Hoseo region can be seen as the immigration and settlement of Gaya and Wa in various regions, but the immigration and settlement patterns appear differently. Archaeological data related to the immigration of Gaya are found in various regions, including Cheonan, Asan, Sejong, and Nonsan, and it is estimated that the immigration was most active from the late 4th century to the early 5th century in the Hanseong period. It is presumed that the first pattern of immigration was that fairly high-ranking Gaya people came from Hapcheon region in the late 4th century and that Baekje lived in Cheonan region, and that other regions were also started by the aftermath. Although the hierarchy and immigration situation vary depending on the region, it is estimated that the Gaya people played various roles, such as the growth of local forces and exchanges with Gaya, While cooperating with Baekje's central and local forces after moving to the Hoseo region. A small number of archaeological data related to the immigration of Wa are found on tombs in Cheonan and Cheongju regions, and the period supposed to be early and middle of the 5th century. In terms of tombs and artifacts it is presumed that the immigration of Wa people was small and military, and according to the political situation of confrontation with Goguryeo in the Hanseong period, it was assumed that they entered Baekje for military activities and settled in the Hoseo region without returning.
