Soseono (Korean: 소서노; Hanja: 召西奴; 66/7 – 6 BC) or Yeon Soseono (연소서노; 延召西奴) was the second wife of King Dongmyeong and a key figure in the establishment of both Goguryeo and Baekje.
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 left Goguryeo and took her two sons, Biryu and Onjo, south to found their own kingdom, Baekje.
