Danjong (Korean: 단종; Hanja: 端宗; 18 August 1441 – 17 November 1457[a]), personal name Yi Hong-wi (이홍위; 李弘暐), was the sixth monarch of the Joseon dynasty of Korea.

His mother, Crown Princess Consort Gwon (posthumously honored as Queen Hyeondeok), didn't recover after giving birth and died the next day.

[3] In 1453, this government was overthrown in a coup d'état led by his uncle, Grand Prince Suyang (posthumously called King Sejo), who persuaded a number of scholars and officials who had served in the court of Sejong the Great to support his claim to the throne.

However, he began perceiving that Danjong would present a continuing threat to his rule, Sejo accepted the advice of the court and ordered that his nephew be disposed of.

After 200 years, in 1698, the demoted Prince Nosan and his wife were finally restored, receiving the temple name "Danjong", and posthumous name "Queen Jeongsun".
