We are saddened by the death of Manuel Marulanda, commander in chief of the Revolutionary Armed Forces of Colombia-People's Army (FARC-EP). At the same time, we are inspired by the powerful example of his life and work. Marulanda embodied the struggle of the Colombian people for national liberation and socialism. He was both a Colombian patriot and an internationalist – a persistent advocate for a united Latin America free from domination by U.S. imperialism. Marulanda was a Great Liberator, in the tradition of the Simon Bolivar.
