Behind every major event of the Imjin War stood real people making difficult decisions under enormous pressure. Some became legendary figures in Korean history, while others are remembered mainly through the roles they played in this specific conflict.
Getting to know these figures helps humanize a war that can otherwise feel like an abstract sequence of dates and battles.
This article introduces the most important people connected to the Imjin War, from military leaders to political figures.
Admiral Yi Sun-sin
Widely regarded as Korea's greatest naval commander, Yi Sun-sin led a series of decisive victories throughout the war, including at Hansando and Myeongnyang. He faced political setbacks during the conflict, including a period of demotion and imprisonment, yet returned to lead Korea's navy until his death in the war's final battle.
King Seonjo
As Joseon's reigning monarch, Seonjo faced the difficult task of leading a kingdom under invasion. His decision to flee the capital drew criticism, but he also played a central role in securing Ming Chinese military support throughout the war.
Toyotomi Hideyoshi
The Japanese leader who ordered the invasion, Hideyoshi directed the war from Japan without ever traveling to Korea. His death in 1598 directly led to Japan's withdrawal and the war's end.
Ryu Seong-ryong
A key Joseon official and military strategist, Ryu Seong-ryong played a major role in coordinating Korea's defense efforts and later wrote an important historical account of the war, offering valuable insight for modern historians.
