Fidel Castro led an unsuccessful attack on the Moncada army barracks in 1953 in an attempt to overthrow the dictatorship of Fulgencio Batista. Castro and his followers were captured and imprisoned but released in 1955. Castro then went into exile in Mexico where he organized a rebel army to launch a revolution. In 1959, Castro marched into Havana as Batista fled the country. Castro established a new government but it eventually became a repressive dictatorship. The Cuban economy struggled in the early 1960s due to Castro's policies.
