The Theosophy Society – Adyar is the name of a section of the Theosophical Society founded by Helena Petrovna Blavatsky and others in 1875. Its headquarters moved with Blavatsky and president Henry Steel Olcott from New York to Adyar, an area of Chennai, in 1886. The designation 'Adyar' is added to make it clear that this is the Theosophical Society headquartered there, after the American section and some other lodges separated from it in 1895, under William Quan Judge.
