The Devils of Loudun is a 1952 non-fiction novel by Aldous Huxley.

It is a historical narrative of supposed demonic possession, religious fanaticism, sexual repression, and mass hysteria that occurred in 17th-century France surrounding unexplained events that took place in the small town of Loudun. It centres on Roman Catholic priest Urbain Grandier and an entire convent of Ursuline nuns, who allegedly became possessed by demons after Grandier made a pact with Satan. The events led to several public exorcisms as well as executions by burning.

The book, though lesser known than Huxley’s other books, is considered one of his best works.

Urbain Grandier was a priest burned at the stake at Loudun, France on 18 August 1634. He was accused of seducing an entire convent of Ursuline nuns and of being in league with the devil. Grandier was likely promiscuous and was insolent towards his peers. He had antagonized the Mother Superior, Sister Jeanne of the Angels, when he rejected her offer to become the spiritual advisor to the convent. He faced an ecclesiastical tribunal and was acquitted.

It was only after he had publicly spoken against Cardinal Richelieu that a new trial was ordered by the Cardinal. He was tortured, found guilty and executed by being burnt alive, but never admitted guilt. Huxley touches on aspects of the multiple personality controversy in cases of apparent demonic possession within this book.

The story was adapted into a 1960 stage play by playwright John Whiting. This was, in turn, adapted into the controversial 1971 Ken Russell feature film The Devils, which starred Vanessa Redgrave and Oliver Reed. A 1969 opera based on the play, Die Teufel von Loudun, by Krzysztof Penderecki, was videotaped and released on DVD.

Aldous Leonard Huxley (26 July 1894 – 22 November 1963) was an English writer and philosopher. He wrote nearly 50 books both novels and non-fiction works—as well as wide-ranging essays, narratives, and poems. Born into the prominent Huxley family, he graduated from Balliol College, Oxford, with an undergraduate degree in English literature. Early in his career, he published short stories and poetry and edited the literary magazine Oxford Poetry, before going on to publish travel writing, satire, and screenplays. He spent the latter part of his life in the United States, living in Los Angeles from 1937 until his death. By the end of his life, Huxley was widely acknowledged as one of the foremost intellectuals of his time. He was nominated for the Nobel Prize in Literature nine times and was elected Companion of Literature by the Royal Society of Literature in 1962.

Huxley was a pacifist. He grew interested in philosophical mysticism and universalism, addressing these subjects with works such as The Perennial Philosophy (1945)—which illustrates commonalities between Western and Eastern mysticism—and The Doors of Perception (1954)—which interprets his own psychedelic experience with mescaline. In his most famous novel Brave New World (1932) and his final novel Island (1962), he presented his vision of dystopia and utopia, respectively.
