Carlos Marighella was a Brazilian politician, writer, and Marxist–Leninist militant. Critical of nonviolent resistance to the Brazilian military dictatorship, he founded the Ação Libertadora Nacional, a Marxist–Leninist urban guerrilla group, which was responsible for a series of bank robberies and high-profile kidnappings. He was killed by police in 1969 in an ambush. Marighella's most famous contribution to revolutionary literature was the Minimanual of the Urban Guerrilla.
