During and following the "La Violencia" civil war that erupted in Colombia from the late 1940s to the mid-1950s, the communists developed organic links to several liberal guerrilla and irregular rural forces, most of whom nominally depended on the official Colombian Liberal Party and eventually demobilized by the end of that period. Those groups with more direct relations with the PCC tended to not demobilize, keeping their weapons and organizational structures mostly intact. In 1947, a short-lived Communist Labour Party was formed by former members of the PCC.
