Marquis de Sade

Donatien Alphonse François, Marquis de Sade ( SA(H)D; French: [dɔnasjɛ̃ alfɔ̃s fʁɑ̃swa maʁki də sad]; 2 June 1740 – 2 December 1814) was a French writer, libertine, political activist, and nobleman best known for his libertine novels and imprisonment for sex crimes, blasphemy, and pornography. His works include novels, short stories, plays, dialogues, and political tracts. Some of these were published under his own name during his lifetime, but most appeared anonymously or posthumously.

Born into a noble family dating back to the 13th century, Sade served as an officer in the Seven Years' War before a series of sex scandals led to his detention in various prisons and insane asylums for most of his adult life. During his first extended imprisonment from 1777 to 1790, he wrote a series of novels and other works, some of which his wife smuggled out of prison. On his release during the French Revolution, he pursued a literary career and became politically active, first as a constitutional monarchist then as a radical republican. During the Reign of Terror, he was imprisoned for moderatism and narrowly escaped the guillotine. He was re-arrested in 1801 for his pornographic novels and was eventually incarcerated in the Charenton insane asylum, where he died in 1814.

His major works include The 120 Days of Sodom, Justine, Juliette and Philosophy in the Bedroom, which combine graphic descriptions of sex acts, rape, torture, murder, and child abuse with discourses on religion, politics, sexuality, and philosophy. The word sadism derives from his fictional characters who take pleasure in inflicting pain on others.

There is debate over the extent to which Sade's behavior was criminal and sadistic. Peter Marshall states that Sade's "known behaviour (which includes only the beating of a housemaid and an orgy with several prostitutes) departs greatly from the clinical picture of active sadism". Andrea Dworkin, however, argues that the issue is whether one believes Sade or the women who accused him of sexual assault.
