who was the founder of theosophy which gave rise to many magical societies
Theosophy From the late 19th century onwards, the term theosophy has generally been used to refer to the religio-philosophic doctrines of the Theosophical Society, founded in New York City in 1875 by Helena Blavatsky, William Quan Judge, and Henry Steel Olcott. Blavatsky's major work, The Secret Doctrine (1888), was one of the foundational works of modern theosophy.[3] As of 2015[update], members of organizations descended from, or related to, the Theosophical Society were active in more than 52 countries around the world.[a] Modern theosophy has also given rise to, or influenced, the development of other mystical, philosophical, and religious movements.[4]
