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.

Seonjo, personal name Yi Yeon, was the 14th monarch of the Joseon period of Korea. He was known for promoting Confucianism and attempting reforms at the beginning of his reign. However, he later gained infamy from the political discord and incompetent leadership during the Japanese invasions of Korea.
