After the takeover, anti-Batistas, liberals, urban workers, peasants, and idealists became the dominant followers of the M-26-7 movement, which gained control over Cuba. The Movement was joined with other bodies to form the United Party of the Cuban Socialist Revolution, which in turn became the
Communist Party of Cuba in 1965. Cuba modeled itself after the Eastern European nations that made up the
Warsaw Pact, becoming the first socialistic government in the Americas. Once it was learned that Cuba would adopt a strict Marxist–Leninist political and economic system, opposition was raised not only by dissident party members, but by the United States as well. Fidel Castro's government seized private land, nationalized hundreds of private companies—including several local subsidiaries of U.S. corporations—and taxed American products so heavily that U.S. exports were cut in half in just two years. The Eisenhower Administration then imposed trade restrictions on everything except food and medical supplies. As a result, Cuba turned to the Soviet Union for trade instead. The US responded by cutting all diplomatic ties to Cuba and has had a rocky relationship with the country ever since. In April 1961, a CIA-trained force of
Cuban exiles and dissidents, including former supporters of the M-26-7, launched the unsuccessful
Bay of Pigs Invasion against Cuba, shortly after Castro had declared the revolution socialist. After the invasion, Castro formally proclaimed himself a
communist. Despite the support that the M-26-7 received from many Catholic students and priests during the fight against Batista, the movement's victory in 1959 created a split between the M-26-7 and Catholic Church, which resisted the agrarian reform program and what members of the Church saw as Castro's turn to Soviet Communism. Following the National Catholic Congress's protest against the lack of Catholic values in the policies of the M-26-7 and a riot on 17 July 1959 in front of the
Cathedral of Havana involving representatives of the Catholic Church and pro-Castro protestors, Castro publicly denounced the leadership of the Roman Catholic church on 12 August. On 6 January 1960, M-26-7 militants then occupied Catholic seminaries, churches, and schools across Cuba and arrested the leaders of the Young Catholic Workers (JOC). After the Bay of Pigs invasion, the M-26-7 closed more churches and detained a number of priests and bishops on 17 April 1961, and the Catholic Church was expelled from Cuba on 1 May in the wake of the nationalization of all private colleges and the expulsion of foreign priests from the island. == Legacy ==
