The Bolivian Diary of Ernesto Che Guevara presents the daily chronicle of Ernesto Che Guevara's Bolívia guerrilla campaign from November 1966 until his capture and death in October 1967. Guevara's own diary entries, supplemented by letters, political statements and accounts from fellow combatants, document his efforts to build a continent-wide movement of workers and peasants capable of challenging imperialism and achieving socialist revolution. The volume includes the first English translations of selected materials such as My Campaign with Che by Bolivian leader Inti Peredo, as well as introductions by Mary-Alice Waters and additional contextual materials. The narrative offers intimate insight into the strategic decisions, daily hardships, moral reflections, and evolving revolutionary thought that defined Guevara's final campaign. Ernesto Che Guevara (1928-1967) was an Argentine-born physician, revolutionary, author, and guerrilla leader central to the Cuban Revolution and subsequent global socialist movements. After completing medical studies, Guevara traveled extensively in Latin America, experiences that shaped his critique of imperialism and class oppression. He became a key commander in the Cuban Revolution, later holding government posts. In 1966 he resigned his official roles to lead armed insurgencies abroad, culminating in the Bolivian campaign documented in this diary.
