Onjo of Baekje

Onjo is the legendary founder of Baekje, said by the Samguk sagi to have been a son of Jumong, founder of Goguryeo. According to tradition, he left the north with followers and founded the kingdom in 18 BCE at Wiryeseong, on the Han river near modern Seoul, while his brother Biryu settled at Michuhol. Historians treat the account as legend reflecting Baekje's origins among migrants from the north.
