What happened before Fidel Castro assumed power in 1959

On February 16, 1959, Fidel Castro is sworn in as prime minister of Cuba after leading a guerrilla campaign that forced right-wing dictator Fulgencio Batista into exile. Castro, who became commander in chief of Cuba's armed forces after Batista was ousted on January 1, replaced the more moderate Miro Cardona as head of the country's new provisional government.
