Carrillo became the General Secretary of the PCE in 1960, replacing Dolores Ibárruri ("La Pasionaria"), who was given the honorary post of Party Chairman. Carrillo's policies were aimed at strengthening the party's position among the working class and intellectual groups , and survived opposition from Marxist–Leninist, Stalinist and social democratic factions. In 1968, when the Soviets and Warsaw Pact countries invaded Czechoslovakia, Carrillo distanced the party from Moscow.
