Guerrilla movements in Colombia in the context of Paramilitarism in Colombia

Right-wing paramilitary groups in Colombia (Spanish: paramilitares de derecha) are paramilitary groups acting in opposition to revolutionary Marxist–Leninist guerrilla forces and their allies among the civilian population. These right-wing paramilitary groups control a large majority of the illegal drug trade in Colombia of cocaine and other substances. The Colombian National Centre for Historical Memory has estimated that between 1981 and 2012 paramilitary groups have caused 38.4% of the civilian deaths, while the Guerillas are responsible for 16.8%, 10.1% by the Colombian Security Forces and 27.7% by non-identified armed groups.

The first paramilitary groups were organized by the Colombian military following recommendations made by U.S. military counterinsurgency advisers who were sent to Colombia during the Cold War to combat leftist political activists and armed guerrilla groups. The development of more modern paramilitary groups has also involved elite landowners, drug traffickers, members of the security forces, politicians, civilians, and multinational corporations. Paramilitary violence today is principally targeted towards supposed left-wing insurgents and their supporters.
