The Marquis de Sade spent twenty-seven years in prison

Donatien Alphonse François de Sade remained locked up for twenty-seven years out of the seventy-four years of his existence. He experienced detention under the monarchy, the Republic, the Consulate, and the Empire, due to his crimes, his pornographic writings, and his anticlerical atheism. He finally died in 1814 while in detention at the Charenton insane asylum.
