The Qing invasion of Joseon occurred in the winter of 1636 when the newly-established Qing dynasty invaded the Joseon dynasty, establishing the former's status as the hegemon in the Imperial Chinese Tributary System and formally severing Joseon's relationship with the Ming dynasty. The invasion was preceded by the Later Jin invasion of Joseon in 1627.
It resulted in a complete Qing victory over Joseon. After the War, Joseon became a subordinate of the Qing empire and was forced to cut ties with the declining Ming dynasty. Several members of the Joseon royal family were taken hostages and killed as Joseon recognized the Qing dynasty as their new overlord.
