The Cuban Revolution was a successful armed revolt led by Fidel Castro and his 26th of July Movement against the authoritarian government of Cuban dictator Fulgencio Batista from 1953 to 1959. This revolution resulted in the establishment of a socialist state in Cuba, which had significant implications for U.S. foreign policy, particularly in terms of Massive Retaliation and covert operations aimed at countering communist influence in the Western Hemisphere.
