The French Revolution played a major role in the development of pornography. The use of X-rated material as a political tool increased substantially leading up to the revolution. Many satirical works used porn to mock political leaders.

Widely considered to be the first pornographic motion picture, A L’Ecu d’Or ou la bonne auberge was released in France in 1908.
