Yi dethrones King Gongyang in his fourth…
1392 CE
Yi dethrones King Gongyang in his fourth year of rule, exiles him to Wonju (where he and his family will be secretly murdered), and ascends the throne.
The Goryeo Dynasty has come to an end after four hundred and seventy-five years of rule.
One of the most widely repeated episodes that occurs in the immediate aftermath of the fall of Goryeo is in 1392, when Taejo's fifth son, Yi Bang-won (later King Taejong), throws a party for the renowned scholar, poet and statesman Jeong Mong-ju, who refuses to be won over by Yi despite their numerous correspondences in the form of archaic poems, and continues to be a faithful supporter the old dynasty, and a leading figure in the opposition to Yi's claim to the throne.
Jeong is revered throughout Goryeo, even by Yi Bang-won himself, but he is seen to be an obstacle and as such, in the eyes of supporter of the new dynasty, has to be removed.
After the party, on his way home, Jeong is murdered by five men on the Seonjuk Bridge in Kaeseong.
This bridge will become a national monument of North Korea, and a brown spot on one of the stones is said to be a bloodstain of his that turns red when it rains.
