The Kapsan Faction Incident was an unsuccessful attempt to undermine the power of Kim Il-sung, the leader of North Korea, around the year 1967. The "Kapsan faction" was a group of veterans of the anti-Japanese struggle of the 1930s and 1940s that was initially close to Kim Il-sung. In the wake of the 2nd Conference of the Workers' Party of Korea (WPK) in 1966, the faction sought to introduce economic reforms, challenge Kim Il-sung's cult of personality, and appoint its ringleader Pak Kum-chol as his successor.
