Injo of Joseon (조선 인조) (7 December 1595 – 17 June 1649), born as Yi Jong, was the sixteenth ruler of the Joseon Dynasty of Korea. He was the grandson of King Seonjo and son of Prince Jeongwon. He was the king during the Later Jin invasion of Joseon, in which Later Jin withdrew the armies after their demands were met. However, in the subsequent Qing invasion, King Injo surrendered in 1636, agreeing to the subjugating terms outlined by the Qing. Yi Jong is considered a weak and incompetent ruler as during his reign, Korea experienced the Yi Gwal's Rebellion, invasions from the Later Jin and Qing dynasty, and an economic recession.
