Establishment of two kingdoms

The 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 Holbon^[1] and the second wife of Jumong. The same source states that the chief of the Habaek tribe had given his daughter, Lady Ye, in marriage to Jumong and she was his first wife. Soseono's first husband was Wutae.

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

Death

• 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.
