Yi Won-gye (1330–1388) or formally called Grand Prince Wanpung, was a warrior and painter in the late Goryeo periods who became part of the early Joseon dynasty royal family member as the oldest child and son of Yi Jachun, making him half brother to Yi Seonggye, its founder.
After repulsed the Hong Geon-jeok rebellion and Japanese rebellion in the late Goryeo dynasty era, Yi was appointed as the Prince Cheoksan (척산군; 陟山君) and later Prince Wansan (완산군; 完山君). He was recorded to died a few days after leaving a desperate poem and knowing that his brother wanted to destroy Goryeo and made a new dynasty by poisoned himself and committed suicide in 1388. Then, after the Joseon dynasty was established in 1392, he was given title as Count Wansan (완산백; 完山伯) and formally became a "daegun" in 1872 during King Gojong's reign.
