The "I AM" Activity Movement is the original ascended master teachings religious movement founded in the early 1930s by Guy Ballard and his wife Edna Anne Wheeler Ballard in Chicago, Illinois. It is an offshoot of theosophy and a major precursor of several New Age religions including the Church Universal and Triumphant.
The movement had up to a million followers in 1938 and is still active today on a smaller scale. Upon Ballard's death, several members founded their own splinter groups, adding their own beliefs and teachings to those of the original movement.
