Hyo-sim
Leader of the 1193 peasant uprising at Chojeon (Ulsan), allied with Kim Sa-mi of Unmun
Rising with Chojeon as his base, he joined Kim Sa-mi of Unmun to fight government forces across Gyeongsang. He held out after Kim Sa-mi’s death, but his band collapsed after a heavy defeat at Miryang in 1194. It is counted the largest peasant uprising of the military-regime period.
