About Santiago Carrillo
Santiago José Carrillo Solares (18 January 1915 – 18 September 2012) was a Spanish politician who served as General Secretary of the Communist Party of Spain (PCE) from 1960 to 1982. He was exiled during the dictatorship of Francisco Franco, becoming a leader of the democratic opposition to the regime. His role as leader of the PCE made him a key figure in the transition to democracy. He later embraced Eurocommunism and democratic socialism, and was a member of the Congress of Deputies from 1977 to 1986. In 1932, Carrillo joined the Executive Commission of the Socialist Youth and became editor of its newspaper, Renovación. Carrillo became the General Secretary of the PCE in 1960, replacing Dolores Ibárruri (La Pasionaria), who was given the honorary post of Party Chairman.
