Establishing of two kingdomsEdit

A traditional account from the Annals of Baekje section in the Samguk Sagi, states that Soseono was the daughter of Yeon Ta-bal, a wealthy influential figure in Jolbon[1] and married to Jumong. However, the same source officially states that the chief of Habaek tribe gave his daughter to Jumong, who had fled Eastern Buyeo with his followers, in marriage. According to the Samguk Sagi, Jumong was Lady Soseono's second husband. Her first husband was Wutae.

After Jumong's son, Yuri of Goguryeo, and Yuri's mother, Ye So-ya, who were both presumed to have died, returned to Goguryeo, Yuri became the crown prince of Goguryeo. Soseono left Goguryeo, taking her two sons Biryu and Onjo south to found their own kingdom, Baekje.


According to the Samguk Sagi, Soseono died in 6 BCE at the age of 61[2] during the 13th years reign of her second son as the first king of Baekje.
