Ernesto "Che" Guevara (May 14, 1928 – October 9, 1967), commonly known as Che Guevara, El Che, or simply Che, was an Argentine Marxist revolutionary, politician, author, military theorist, physician, and guerrilla leader. His stylized image also later became a countercultural symbol worldwide.
As a young medical student, Guevara travelled through Latin America and was transformed by the endemic poverty he witnessed. His experiences and observations during these trips led him to conclude that the region's inequalities were a result of capitalism, neo-colonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social revolution under President Jacobo Arbenz Guzmán, whose eventual CIA-assisted overthrow solidified Guevara’s radical ideology.
