King Injo was the 16th king of Joseon Dynasty Korea. He came to the throne in 1623 in a coup known as the Injo Revolt, in which the pro-Ming Sŏin faction overthrew Prince Gwanghae and his Puk'in faction, who supported accommodation of the Manchus.
Injo was a son of Prince Gwanghae's younger half-brother, and was thus a nephew of the man he overthrew and succeeded as ruler. Despite Injo's violent overthrow of his predecessor, the Ming court moved quickly to accept him as the new king and formally grant him investiture, in order to help ensure Joseon's aid in defending Ming China against the Manchus.
Ultimately, Injo was forced to submit to Manchu authority in 1637 after a lengthy resistance. He was formally invested by the Manchu leader Hong Taiji that same year. Injo's heir, Prince Sohyeon, taken prisoner during the fighting and brought to the Later Jin dynasty capital at Mukden, was invested by the Later Jin as crown prince of Joseon two years later, in 1639.
