Yi Sun-shin (; April 28, 1545 – December 16, 1598) was a Korean naval commander, famed for his victories against the Japanese navy during the Imjin war in the Joseon Dynasty, and is well-respected for his exemplary conduct on and off the battlefield not only by Koreans, but by Japanese Admirals as well. Military historians have compared his naval genius to that of Admiral Horatio Nelson. His title of Samdo Sugun Tongjesa (삼도수군통제사; 三道水軍統制使), literally meaning "Naval Commander of the Three Provinces," was the title for the commander of the Korean navy until 1896.
