Fidel Castro was the revolutionary leader of Cuba in the 1950s, coming to power after leading a successful uprising against the Batista government in 1959. His leadership represented a significant shift in Cuba's political landscape, transitioning it from a U.S.-aligned dictatorship to a socialist state. Castro's regime implemented land reforms, nationalized industries, and aligned Cuba with the Soviet Union, contributing to heightened tensions during the Cold War. Castro’s revolution inspired leftist movements throughout Latin America and the world, while also provoking stark opposition from the United States, leading to events such as the Bay of Pigs invasion and the Cuban Missile Crisis.
