Gongyang of Goryeo

Gongyang of Goryeo (9 March 1345 – 17 May 1394) was the 34th and final ruler of the Goryeo Dynasty of Korea. He was the descendant of Duke Yangyang, brother of King Huijong. He was deposed by Yi Seong-gye, who then established the new Joseon Dynasty.

Background and early life
He was born as the second and youngest son of Wang Gyun, 6th-generation descendant of King Sinjong from his youngest son, Duke Yangyang. His mother was Princess Boknyeong, a great-granddaughter of King Chungnyeol. He had an older brother, Wang U, Prince Jeongyang. Due to this, the future King had the Goryeo royal family's bloods from both of paternal and maternal line.

At a young age, he was honoured as Prince Jeongchang and then married the daughter of No Chaek, Internal Prince Changseong from the Gyoha No clan. His niece, Lady Kang, married Yi Seong-gye as his second wife.

Reign
Although he did everything to prove that he had no political ambitions, Yi Seong-gye's faction used him as a bloodless propaganda tool. In 1389, Yi's supporters forced King Chang from the throne and enthroned King Gongyang in his stead. This faction went on to oversee the events of King Gongyang's brief reign, including the assassinations of King U and King Chang. After the murder of Chŏng Mong-ju, the last major supporter of the Goryeo kings, King Gongyang was deposed in 1392 by Yi Seong-gye, his son (Yi Bang-won), Jeong Do-jeon and others, which brought the Goryeo dynasty to an end.

Life after deposition
The former king was initially exiled to Wonju and granted the title of Prince Gongyang, but was later moved to Samcheok, where he was assassinated via strangulation in 1394 alongside his son, Crown Prince Wang Seok in Gungchon. In 1416, King Taejong honored him as King Gongyang and sent an envoy to inspect his tomb.
