Im Kkeok-jeong (Korean: 임꺽정; Hanja: 林巪正; 1521–1562[a]) was the leader of a peasant rebellion in the Hwanghae Province during 1559 to 1562, which started due to heavy taxation. His organisation, the Noklimdang, started off as a small group, but grew as they began killing the rich and giving food to the poor. The group of thieves eventually grew to a few hundred. In addition, the group had a wooden castle built.[1] He was also known by other names such as Im Geo-jeong (임거정; 林巨正) and Im Geo-jil-jeong (임거질정; 林巨叱正). Along with Hong Gil-dong and Jang Gil-san, he is sometimes referred to as one of the three great thieves of Joseon, and also considered as one of the four great thieves including Jeon Woo-chi.
