Japanese invasions of Korea (1592–1598)The Japanese invasions of Korea, commonly known as the Imjin War, involved two separate yet linked invasions: an initial invasion in 1592 (), a brief truce in 1596, and a second invasion in 1597 (). The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces. The invasions were launched by Toyotomi Hideyoshi with the intent of conquering the Korean Peninsula and China proper, which were ruled by the Joseon and Ming dynasties, respectively.
