March: In Cuba, Fulgencio Batista staged a bloodless coup d'état on March 10, 1952, removing Carlos Prio Socarras (elected in 1948) and becoming President. The new government received diplomatic recognition from the United States, a number of American corporations continued to swell in Cuba, and the island became a major tourist destination, attracting unprecedented prosperity for the island. But the economic depressions of the 1950s and Batista's corruption, particularly his unsettlingly close relationship with the Havana Mafia, saw a rise in opposition to his regime, particularly from poorer Cubans and younger-generation, middle-class Marxist thinkers who felt marginalized in their own country.
Negotiations put an end to the Cuban Civil War. Batista would leave the presidential office in 1964.
A ballot held in Cuba favours the annexation to the United States. Cuba formally applies to annexation and statehood. US congress approves annexation under a commonwealth status and the question of statehood would follow negotiations.
In a referendum to chose the Puerto Rican status, the Statehood option wins a plurality of the votes (48%) over the Commonwealth status (47%). The Independence option barely got a 4% figure.
Cuba was admitted in March as the 51st state of the United States of America.
Puerto Rico was admitted in November as the 52nd state of the United States of America.
