Between 1875 and 1947, a period bookended, respectively, by the founding of the Theosophical Society and the death of notorious occultist celebrity Aleister Crowley, Britain experienced an unparalleled efflorescence of engagement with unusual occult schema and supernatural phenomena such as astral travel, ritual magic, and reincarnationism.
