Overview
The Theosophical Society is an occult and esoteric movement founded in New York City in 1875 by the Russian émigré Helena Petrovna Blavatsky, the American lawyer Henry Steel Olcott and William Quan Judge, drawing on a long theosophical tradition traced back to ancient Gnosticism and Neoplatonism. Blavatsky, its chief theoretician, taught that all world religions preserve fragments of a single ancient wisdom. The society's three declared objects are to form a nucleus of universal human brotherhood, encourage comparative study of religion, philosophy and science, and investigate the hidden powers latent in nature and humanity. Having relocated to India, where its international headquarters at Adyar remain today, the society proved small but highly influential, serving as a conduit for Hindu and Buddhist ideas into the West and inspiring more than a hundred later esoteric movements.[1, 3–4, 6–7]
History

Blavatsky, Olcott and the society's founding 1875–1891
Blavatsky, after years of travel through Europe and the Middle East, met Olcott, a Spiritualist investigator, at gatherings in Chittenden, Vermont; the Theosophical Society grew directly out of further evening gatherings the two held in Blavatsky's New York apartment in 1875, with Judge serving as counsel. Blavatsky set out her cosmology in Isis Unveiled (1877) and, more fully, in the two-volume Secret Doctrine (1888). Olcott and Blavatsky then left for India, eventually settling at Adyar near Madras, still the society's international headquarters. In 1884–85 a Society for Psychical Research investigator concluded that Blavatsky had faked the phenomena accompanying her claimed messages from hidden spiritual Masters, a finding that damaged the society for the rest of her life, though a later re-examination called it biased.[2–3, 5, 8]
Besant, Krishnamurti and the society's peak 1891–1929
After Blavatsky's death in 1891, the British activist Annie Besant, who had joined the society two years earlier, became its leading figure, succeeding Olcott as international president on his death in 1907 and winning the society its greatest following, partly through her support for Indian independence. A dispute over leadership of the esoteric section led Judge to take most American lodges out of the parent society in 1895, forming an independent body now headquartered in Pasadena, California. With her colleague Charles Webster Leadbeater, Besant promoted the young Jiddu Krishnamurti as the coming World Teacher, touring the world with him in the 1920s until he broke with the society in 1929, after which its membership never fully recovered.[9–11]

How we know
The 1885 Hodgson Report
The society's early credibility rested partly on phenomena surrounding Blavatsky's claimed letters from hidden spiritual Masters; in 1885 Richard Hodgson of the Society for Psychical Research investigated and declared her an imposter, a finding a later re-examination by another SPR member called biased and based on misread handwriting evidence.[5]
Common misconceptions
Myth Theosophy requires members to believe a fixed set of doctrines, such as karma and reincarnation.
Fact The Theosophical Society asks members to subscribe only to its Three Objects; concepts such as karma and reincarnation, though widely taught by Blavatsky and later theosophists, have no official status binding on members, and the society states that it has no creed to enforce.[4]
Myth Blavatsky's claimed psychic phenomena and letters from hidden Masters were proven genuine.
Fact A Society for Psychical Research investigation in 1885 concluded the phenomena were faked, though a later re-examination argued the original report was biased and misread the handwriting evidence; the matter remains disputed rather than settled in either direction.[5]
