In 1959, the revolutionary leader Fidel Castro became prime minister of Cuba.
The government initiated the nationalization of the economy, especially foreign ownership, and land reform. In protest of these measures, the U.S. government imposed a trade embargo in 1960 (which continues to this day) and broke off diplomatic relations a year later. As a result of the revolution, about two million people emigrated from Cuba, mainly to the U.S. (in 1961, emigrants organized in the Central Intelligence Agency carried out an invasion of the Bay of Pigs). After these actions by the US, Castro contacted the Soviet Union. The Communist Party of Cuba was founded and has ruled the country since 1965.
