After the communist revolution of 1959,[10] the Cuban government restricted religious practice. Religious people were not allowed to join the Cuban Communist Party due to religion being contradictory to the party's Marxist philosophy. In August 1960, several bishops signed a joint pastoral letter condemning communism and declaring it incompatible with Catholicism, and calling on Catholics to reject it.[11] Castro gave a four-hour speech the next day, condemning priests who serve "great wealth" and using fears of Falangist influence to attack Spanish born priests, declaring "There is no doubt that Franco has a sizeable group of fascist priests in Cuba."
