Life
Yi Bang-beon was the seventh prince of King Taejo Yi Seong-gye, born to the king's secondary wife, Queen Sindeok of the Gang clan (神德王后 康氏). In 1387, while still a child, he married a daughter of Gwiui Gun (Jeongyang Gun) Wang U1. In 1390, during the reign of his wife's uncle, King Gongyang of Goryeo (高麗 恭讓王), he received the post of Gogong Jwarang from the Goryeo dynasty, supported by his father Yi Seong-gye. After the founding of Joseon in July 1392 (1st year of King Taejo), he was invested as Muan Gun and appointed Commander of the Uiheung Chingun Wi (義興親軍衛節制使).
In the 2nd year of King Taejo (1393), at the age of 13, he was appointed Commander of the Left Army. For a time, at the recommendation of his father King Taejo Yi Seong-gye and his mother Queen Gang, he was even tentatively designated as crown prince. However, senior ministers including Jo Jun (趙浚) and Jeong Do-jeon (鄭道傳) opposed him, calling him "violent, reckless, and rash," and the crown prince position went to his full younger brother, Yi Bang-seok. He was then enfeoffed as Muan Gun.
