The Marquis de Sade (1740–1814) was a French aristocrat, sexual libertine, political radical, philosopher, and writer whose work led to the coinage of the terms sadism and sadist. His works combine philosophical discourse with pornography, depicting sexual fantasies with violent, criminal, and blasphemous elements in support of his belief in unrestrained individual freedom.
