Aleister Crowley Mary Desti Leila Waddell

Aleister Crowley, born Edward Alexander Crowley in 1875, was an English occultist, magician, and writer who rejected his Christian upbringing to explore Western esotericism. He became a significant figure in occult circles, joining the Hermetic Order of the Golden Dawn and later co-founding the A∴A∴. Crowley established the religion of Thelema, based on a text he claimed was dictated by a supernatural entity, emphasizing the principle of "Do what thou wilt."

Throughout his life, Crowley traveled extensively, studying various spiritual practices and engaging in mountaineering and poetry. He published numerous works on occult subjects, poetry, and novels. His association with esoteric orders like the Ordo Templi Orientis (O.T.O.) led to the establishment of Thelemite groups internationally. Crowley's unconventional lifestyle and beliefs brought him notoriety, and he spent his later years promoting Thelema until his death in 1947. He remains an influential figure in Western esotericism and counterculture.

Born into a wealthy family, Edward Alexander Crowley abandoned his parents' fundamentalist Christian faith to pursue his interest in Western esotericism. Educated at Cambridge, he focused on mountaineering and poetry, but also developed a keen interest in the occult after a brief illness prompted existential reflection. He acquired key occult texts and began publishing poetry, some of which, like 'White Stains,' was printed abroad due to its erotic content. He left Cambridge without a degree, dedicating himself to his esoteric pursuits.

In 1898, Crowley joined the Hermetic Order of the Golden Dawn, where he received training in ceremonial magic from prominent figures like Samuel Liddell MacGregor Mathers and Allan Bennett. He adopted the magical name 'Frater Perdurabo.' After leaving the Golden Dawn, he co-founded the A∴A∴ in 1907 with George Cecil Jones to propagate Thelema, a religion he founded based on 'The Book of the Law.' This sacred text, dictated to him by an entity named Aiwass, announced the 'Æon of Horus' and espoused the central tenet 'Do what thou wilt,' encouraging followers to align with their True Will through magic.

Crowley became involved with the German Ordo Templi Orientis (O.T.O.) in 1912, eventually leading its British branch and reformulating it in accordance with Thelema, establishing groups in Britain, Australia, and North America. During World War I, he resided in the United States, engaging in painting and controversial political activities. In 1920, he established the Abbey of Thelema, a commune in Sicily, but was evicted by the Italian government due to his lifestyle. He spent his remaining decades promoting Thelema across Europe and gained significant notoriety as a drug user, bisexual, and individualist critic, leaving a lasting influence on esotericism and counterculture.
