Donatien Alphonse François, Marquis de Sade (2 June 1740 – 2 December 1814) was a French aristocrat, revolutionary politician, philosopher and writer, famous for his libertine sexuality. His works include novels, short stories, plays, dialogues and political tracts; in his lifetime some were published under his own name, while others appeared anonymously and Sade denied being their author. He is best known for his erotic works, which combined philosophical discourse with pornography, depicting sexual fantasies with an emphasis on violence, criminality and blasphemy against the Catholic Church. He was a proponent of extreme freedom, unrestrained by morality, religion or law. The words sadism and sadist are derived from his name.
