Like many other Latin American intellectuals, Vargas Llosa was initially a supporter of the Cuban revolutionary government of Fidel Castro. He studied Marxism in depth as a university student and was later persuaded by communist ideals after the success of the Cuban Revolution. Gradually, Vargas Llosa came to believe that socialism was incompatible with what he considered to be general liberties and freedoms. The official rupture between the writer and the policies of the Cuban government occurred with the so-called 'Padilla Affair', when the Castro regime imprisoned the poet Heberto Padilla for a month in 1971. Vargas Llosa, along with other intellectuals of the time, wrote to Castro protesting the Cuban political system and its imprisonment of the artist. Vargas Llosa has identified himself with liberalism rather than extreme left-wing political ideologies ever since. Since he relinquished his earlier leftism, he has opposed both left- and right-wing authoritarian regimes.
