Neo-Theosophy is a term, originally derogatory, used by the followers of Helena Blavatsky to denominate the system of Theosophical ideas expounded by Annie Besant and Charles Webster Leadbeater following the death of Madame Blavatsky in 1891. This material differed in major respects from Blavatsky's original presentation, but it is accepted as genuinely Theosophical by many Theosophists around the world.
