Until I began researching Graham Greene for my thesis, I never realized that Mexico was violently atheistic for a fair portion of the 20th century. Actually, literally, violently anti-God. Plutarco Elías Calles, the Mexican president from 1924-28, declared clerical vestments illegal, divested Catholic clergy of the right to vote, stole church property for the state, and threatened clergy who were critical of the state with imprisonment and death. One particular governor, Tomás Garrido Canabal, went so far as to actually hunt down practicing priests. A profane man both privately and publicly, the governor's atheism was so exaggerated that he named his children Lenin and Zoila Libertad (he also had a nephew named Lucifer), and chose to call his farm animals "God," "Pope," "Mary," and "Jesus."
According to Wikipedia, he encouraged a local satirical play which featured a stud bull being paraded around "called 'the bishop' or an ass labeled 'the pope.'”
