Gwon Yul was a Korean army general and the commander-in-chief of the Joseon period, who successfully led the Korean forces against Japan during the Japanese invasions of Korea. He is best known for the Battle of Haengju where he defeated an attacking force of about 30,000 Japanese with 2,800 troops.

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.
