The Marquis de Sade was born in the Condé palace, Paris, to Comte Jean-Bastiste François Joseph de Sade and Marie-Eléonore de Maillé de Carman, (cousin and lady-in-waiting to the princess of Condé).
He was educated by an uncle, the abbé de Sade. Later, he attended Jesuit lycée, then pursued a military career, becoming Colonel of a Dragoon regiment, and fighting in the Seven Years' War. In 1763, on returning from war, he courted a rich magistrate's daughter, but her father rejected his suit, and, instead, arranged a marriage to his elder daughter, Renée-Pélagie de Montreuil; that marriage engendred two sons and a daughter.
In 1766, he had a private theatre built in his castle at Lacoste in the Provence; in January of 1767, his father died.
The de Sade men alternated using the marquis (marquess) and comte (count) titles. His grandfather, Gaspard François de Sade, was the first to use marquis; occasionally, he was the Marquis de Sade, but is documentarily identified as the Marquis de Mazan. The de Sade family were Noblesse d'épée, of the oldest, Frank-descended nobility, so, assuming a noble title without a King's grant, was customarily de rigueur. Alternating title usage indicates that titular hierarchy (below duc et pair) was notional; theoretically, the marquis title was granted to noblemen owning several countships, but its use by men of dubious lineage caused its disrepute. At Court, precedence was by seniority and royal favour, not title. There is father-and-son correspondence, wherein father addresses son as marquis.
Twentieth-century descendant, the Comte Xavier de Sade, was the first to defend the family name and be interested in the Marquis's controversial work. Until 1948, Comte Xavier had known little of his ancestor because the Marquis de Sade's works went unpublished and unread in France until the 1960s. Thus, when he found a trunk containing journals, letters, manuscripts, and legal documents, he granted access to biographer Gilbert Lêly; the works were published from 1948 to the 1960s. The Comte Xavier and his descendants own the copyrights and the family name, a peculiar legal manoeuver because the Marquis de Sade died and his copyrights expired two centuries earlier.
To avoid association with the Marquis de Sade, descendants have refused the Marquis title, despite all aristocratic titles being dormant since 1848. Bibliographically, the de Sade family have some original manuscripts, others are in universities and libraries, or were destroyed in the eighteenth century. Moreover, the Comte Xavier de Sade founded a winery, honouring the Marquis de Sade, vinting champagne and claret, introduced to market in the late 1980s. Before Comte Xavier, most descendants were against using any of the Marquis's names, yet he named a son Donatien.
One of Sade's first major scandals occurred on Easter Sunday in 1768, in which he procured the sexual services of a woman, Rose Keller whether she was a prostitute or not is widely disputed. He was accused of taking her to his chateau at Arcueil, imprisoning her there and sexually and physically abusing her. She escaped by climbing out of a second-floor window and running away. It was at this time that la Presidente, Sade's mother-in-law, obtained a lettre de cachet from the king, excluding Sade from the jurisdiction of the courts. The lettre de cachet would later prove disastrous for the marquis.
Beginning in 1763, Sade lived mainly in or near Paris. Several prostitutes there complained about mistreatment by him and he was put under surveillance by the police who made detailed reports of his escapades. After several short imprisonments he was exiled to his chateau at Lacoste in 1768.
An episode in Marseille, in 1772, involved the non-lethal poisoning of prostitutes with the supposed aphrodisiac Spanish fly and sodomy with his manservant Latour. That year the two men were sentenced to death in absentia for sodomy and said poisoning. They fled to Italy, Sade took his wife's sister with him and had an affair with her. His mother-in-law never forgave him for that. She obtained a lettre de cachet for his arrest (a royal order of arrest and imprisonment, without stated cause or access to the courts).
Sade and Latour were caught and imprisoned at the Fortress of Miolans, in late 1772, but escaped four months later.
Sade later hid at Lacoste where he rejoined his wife who became an accomplice in his subsequent endeavors. He kept a group of young employees at Lacoste, most of whom complained about sexual mistreatment and quickly left his service. Sade had to flee to Italy again. During this time he wrote Voyage d'Italie, which, along with his earlier travel writings, has never been translated into English. In 1776 he returned to Lacoste, again hired several servant girls, most of whom fled. In 1777 the father of one of those employees came to Lacoste, to claim her, and attempted to shoot the Marquis at point-blank range. Fortunately for Sade, the gun misfired.
Later that year Sade was tricked into visiting his supposedly ill mother, who in fact had recently died, in Paris. He was arrested there and imprisoned in the Château de Vincennes. He successfully appealed his death sentence in 1778 but remained imprisoned under the lettre de cachet. He escaped but was soon recaptured. He resumed writing and met fellow prisoner Comte de Mirabeau who also wrote erotic works. Despite sharing this in common, the two came to dislike each other immensely.
In 1784 Vincennes was closed and Sade was transferred to the Bastille. On July 2 1789 he reportedly shouted out from his cell, to the crowd outside, "They are killing the prisoners here!" causing somewhat of a riot. Two days later he was transferred to the insane asylum at Charenton near Paris. (The storming of the Bastille, marking the start of the French Revolution, occurred on July 14.)
He had been working on his magnum opus Les 120 Journées de Sodome (The 120 Days of Sodom). To his despair he believed that the manuscript was lost during his transferral; but he continued to write.
He was released from Charenton in 1790 after the new Constituent Assembly abolished the instrument of lettre de cachet. His wife obtained a divorce soon after.
He initially ingratiated himself with the new political situation after the revolution, supported the Republic, called himself "Citizen Sade" and managed to obtain several official positions despite his aristocratic background.
Due to the damage done to his estate in Lacoste which was sacked in 1789 by an angry mob, he moved to Paris. In 1790 he was elected to the National Convention where he represented the far left. He was a member of the Piques section, a section notorious for its radical views. He wrote several political pamphlets, in which he called for the implementation of direct vote. However there is much to suggest that he suffered abuse from his fellow revolutionaries due to his aristocratic background. Matters were not helped by the desertion of his son, a second lietenant and the aide-de-camp to an important colonel the Marquis de Toulengeon, in May 1792. De Sade was forced to disavow his son's desertion in order to save his neck. Later that year his name was entered - whether by error or willful malice - on the list of émigrés of the Bouches-du-Rhone department.
Appalled by the Reign of Terror in 1793, he wrote an admiring eulogy for Jean-Paul Marat to secure his position. Then he resigned his posts, was accused of "moderatism" and imprisoned for over a year. He barely escaped the guillotine, probably due to an administrative error. This experience presumably confirmed his life-long detestation of state tyranny and especially of the death penalty. He was released in 1794, after the overthrow and execution of Maximilien Robespierre had effectively ended the Reign of Terror.
In 1796, now all but destitute, he had to sell his ruined castle in Lacoste. The ruins of the castle were acquired in the 1990s by fashion designer Pierre Cardin who now holds regular theater festivals there.
After intervention by his family, he was declared insane in 1803 and transferred once more to the asylum at Charenton. His ex-wife and children had agreed to pay his pension there.
Constance was allowed to live with him at Charenton. The benign director of the institution, Abbé de Coulmier, allowed and encouraged him to stage several of his plays, with the inmates as actors, to be viewed by the Parisian public. Coulmier's novel approaches to psychotherapy attracted much opposition. In 1809 new police orders put Sade into solitary confinement and deprived him of pens and paper, though Coulmier succeeded in ameliorating this harsh treatment.
In 1813, the government ordered Coulmier to suspend all theatrical performances.
Sade began an affair with 13-year-old Madeleine Leclerc, daughter of an employee at Charenton. This affair lasted some 4 years, until Sade's death in 1814. He had left instructions in his will to be cremated and his ashes scattered but, instead, he was buried in Charenton. His skull was later removed from the grave for phrenological examination. His son had all his remaining unpublished manuscripts burned, including the immense multi-volume work Les Journées de Florbelle.
Numerous writers and artists, especially those concerned with sexuality, have been both repelled and fascinated by de Sade.
The contemporary rival pornographer Rétif de la Bretonne published an Anti-Justine in 1793.
Simone de Beauvoir (in her essay Must we burn Sade?, published in Les Temps modernes, December 1951 and January 1952) and other writers have attempted to locate traces of a radical philosophy of freedom in Sade's writings, preceding modern existentialism by some 150 years. He has also been seen as a precursor of Sigmund Freud's psychoanalysis in his focus on sexuality as a motive force. The surrealists admired him as one of their forerunners, and Guillaume Apollinaire famously called him "the freest spirit that has yet existed".
Pierre Klossowski, in his 1947 book Sade Mon Prochain ("Sade My Neighbor"), analyzes Sade's philosophy as a precursor of nihilism, negating both Christian values and the materialism of the Enlightenment.
One of the essays in Max Horkheimer and Theodor Adorno's Dialectic of Enlightenment (1947) is titled "Juliette or Enlightenment and Morality" and interprets the ruthless and calculating behavior of Juliette as the embodiment of the philosophy of enlightenment. Similarly, psychoanalyst Jacques Lacan posited in his 1966 essay "Kant avec Sade" that de Sade's ethic was the complementary completion of the categorical imperative originally formulated by Immanuel Kant.
In his 1988 Political Theory and Modernity, William E. Connolly analyzes Sade's Philosophy in the Bedroom as an argument against trend of earlier political philosophers, notably Rousseau and Hobbes, and their attempts to reconcile nature, reason and virtue as basis of ordered society.
In The Sadeian Woman: And the Ideology of Pornography (1979), Angela Carter provides a feminist reading of Sade, seeing him as a "moral pornographer" who creates spaces for women. Similarly, Susan Sontag defended both Sade and Georges Bataille's Histoire de l'oeil (Story of the Eye) in her essay, "The Pornographic Imagination" (1967) on the basis their works were transgressive texts, and argued that neither should be censored.
By contrast, Andrea Dworkin saw Sade as the exemplary woman-hating pornographer, supporting her theory that pornography inevitably leads to violence against women. One chapter of her book Pornography: Men Possessing Women (1979) is devoted to an analysis of Sade. Susie Bright claims that Dworkin's first novel Ice and Fire, which is rife with violence and abuse, can be seen as a modern re-telling of Sade's Juliette.
He is name-checked by the DC Comics character Desaad; was a secondary character in the Grant Morrison's graphic novel series The Invisibles and in 2000 Guido Crepax created graphic novel combining Justine with Anne Desclos's Histoire d'O, supposedly following Sade's example of creating beauty from the vile and the degenerate.
