Óscar Pérez Solís

Óscar Pérez Solís was a Spanish artillery officer, engineer, journalist and politician. He became attracted to left-wing causes, and left the army in 1912. He joined the Spanish Socialist Workers' Party and was its candidate in several general elections. In 1921 he was one of the founders of the Communist Party of Spain, and became secretary-general of the party. He converted to Catholicism during a period in prison in 1925–27. After being released he disavowed his left-wing beliefs and became associated with the right-wing Falangists.
