The kingdom of Baekje was located on the southwestern tip of the Korean Peninsula.

Traditionally founded in the Gwangju area, the kingdom expanded significantly by the 4th century to encompass the entire Han River basin in central Korea. However, following territorial losses to the northern kingdom of Goguryeo, Baekje was forced to relocate its capital southward, first to Ungjin (modern-day Gongju) and later to Sabi (modern-day Buyeo).1
