Cuba is an island nation in the Caribbean Sea whose capital and largest city is Havana. The population of Cuba is approximately 11.5 million people, most of whom are Roman Catholic. The economy is largely state-controlled and centered around exports like sugar, tobacco, and coffee. Cuba has a long history dating back to indigenous peoples and Spanish colonization. It gained independence in the late 19th century but has had a tumultuous relationship with the United States, leading to the Cuban Revolution in the 1950s and establishment of a communist government under Fidel Castro.
