This galvanized Chicano youth to focus on anti-war activism, "especially influenced by the Third World movements of liberation in Asia, Africa, and Latin America." Historian Mario T. García reflects that "these anti-colonial and anti-Western movements for national liberation and self-awareness touched a historical nerve among Chicanos/as as they began to learn that they shared some similarities with these Third World struggles." Chicano poet Alurista argued that "Chicanas/os cannot be truly free until they recognize that the struggle in the United States is intricately bound with the anti-imperialist struggle in other countries." The Cuban Revolution (1953–59) led by Fidel Castro and Che Guevara was particularly influential to Chicanos, as noted by García, who notes that Chicanas/os viewed the revolution as "a nationalist revolt against "Yankee imperialism" and neo-colonialism."
