In 1959, the Cuban Revolution led to the victory of Fidel Castro and his July 26 Movement. Although the revolution was not explicitly socialist, upon victory Castro ascended to the position of prime minister and adopted the Leninist model of socialist development, forging an alliance with the Soviet Union. One of the leaders of the revolution, the Argentine Marxist revolutionary Che Guevara, subsequently went on to aid revolutionary socialist movements in Congo-Kinshasa and Bolivia, eventually being killed by the Bolivian government, possibly on the orders of the Central Intelligence Agency (CIA), although the CIA agent sent to search for Guevara, Felix Rodriguez, expressed a desire to keep him alive as a possible bargaining tool with the Cuban government. He posthumously went on to become an internationally recognised icon.
