Grand Prince Yangnyeong (Hangul: 양녕대군, Hanja: 讓寧大君, 1394–1462) was a Joseon Dynasty politician and prince. The Grand Prince, first-born son of King Taejong of the Joseon Dynasty and his consort Queen Wongyeong, elder brother of Sejong the Great, and ancestor of Syngman Rhee[citation needed], Korean independence activist and first President of South Korea.


He was born as Yi Je (李褆 in Hanja, 이제 in Hangul) in 1394. Known for his literature and calligraphy skills, he viewed himself as lacking in the requisite skills for kingship and believed that Sejong was destined to become king. Considering it his duty to make Sejong king, he purposely acted extremely rude in the court, lost his position as a prince, married a peasant and was eventually officially banished from Seoul in June 1418. Grand Prince Hyoryeong, Yangnyeong's second brother, had similar feelings about Sejong being king, and so became a monk in a Buddhist temple. This plot ultimately brought Sejong to the throne. Later, Yangnyeong became a wandering traveler and lived in the mountains.[1]

After Sejong has taken the throne, the relationship between the brothers was strong, and Sejong often invited Yangnyeong to the palace.

Yangnyeong lived as a wanderer and died in 1462, almost living for 68 years.[2]
