15. Kim Cheo-seon: Korea’s Unexpected War Hero
Kim Cheo-seon served as a palace eunuch during Korea’s Joseon Dynasty until Japan invaded in 1592. When Korean armies collapsed and the court fled north, Kim organized a volunteer fighting force from his home region. With no military training, he led successful guerrilla attacks against Japanese forces, helping protect his country when conventional defenses failed. His knowledge of court protocol, combined with regional connections, helped him mobilize resistance when the formal military structure collapsed.
