In 1492, Christopher Columbus landed on and claimed the island now occupied by Cuba, for the Kingdom of Spain. Cuba remained a territory of Spain until the Spanish–American War ended in 1898, and gained formal independence from the U.S. in 1902. A fragile democracy, increasingly dominated by radical politics eventually evolved, solidified by the Cuban Constitution of 1940, but was definitely quashed in 1952 by former president Fulgencio Batista, and an authoritarian regime was set up, intensifying and catalyzing already rampant corruption, political repression and crippling economic regulations. Batista was ousted in January 1959 by the July 26 movement, and a new administration under Fidel Castro established, which had by 1965 evolved into a single-party state under the revived Communist Party of Cuba, which holds power to date. Cuba is home to over 11 million people and is the most populous island nation in the Caribbean, as well as the largest by area. Its people, culture, and customs draw from diverse sources, such as the aboriginal Taíno and Ciboney peoples, the period of Spanish colonialism, the introduction of African slaves and its proximity to the United States.
