Yi Jachun
Yi Ja-chun was a minor military officer of the Yuan Dynasty and the father of Yi Seong-gye, the founder of the Joseon Dynasty. He was given the temple name Hwanjo by Taejong.
Yi Ja-chun was a mingghan of the Yuan Dynasty in Ssangseong Prefectures, After Ssangseong was annexed by Goryeo under King Gongmin, he migrated to Hamju, Hamgyŏngnamdo and got promoted to manho. He married a Chinese lady from Shandong, who became Queen Uihye, the mother of Yi Taejo. He died in Hamgyong in 1361.
Since he was glamorized by his descendants, descriptions of Yi Ja-chun's life tend to be contradictory to each other. For example, he is said to have risen to the rank of scholar-official. However, when he died, the king at the time expressed condolences for Jachun as if for scholar-officials, implying that Yi Ja-chun was not a scholar-official.Family
