In 1364, Yi Bang-gan was born in Hamgyong Province as the fourth son of Yi Seong-gye and Lady Han, of the Cheongju Han clan.
He married Lady Min, daughter of Min Seon (민선).The couple had only one son. His second wife was Lady Hwang, daughter of Hwang Hyeong (황형), with whom he had four children (1 son and 3 daughters).
Lasty, he married Lady Geum, daughter of Geum In-bae (금인배). Yi Bang-gan had two more sons with his third wife.
After the First Rebellion of the Prince which resulted in the killing of Jeong Do-jeon and Nam Eun, Bang-won's only rival for the throne was his elder brother Yi Bang-gan (Jeongjong).[1] Jeongjong had no sons to succeed him and planned on passing the throne to Yi Bang-won. Prince Hoean became jealous of his younger brother, Yi Bang-won, and in 1400 led a coup d'etat (the Second Rebellion of the Prince) against him.[2] Both princes had built personal armies in secret. Yi Bang-won was able to defeat his brother's army. After the coup, Prince Hoean was exiled and his supporters were killed. This became known as the Second Strife of Princes.
