Carlos Marighella (5 December 1911 – 4 November 1969), was a Brazilian Marxist revolutionary and writer. Marighella's most famous contribution to guerrilla literature was the Minimanual of the Urban Guerrilla, consisting of advice on how to disrupt and overthrow an authoritarian regime aiming a revolution. He also wrote For the Liberation of Brazil. The theories laid out in both books have greatly influenced contemporary ideological activism. Unlike Che Guevara, who proposed guerrilla activity in the countryside, Marighela's theories on urban guerrilla warfare envisaged cities as the source of rebellion.
