The history of evolutionary astrology (as a specific term applied to this theory) begins with the work of Jeffrey Wolf Green and Steven Forrest, whose techniques differ but are complementary and based on the same theory. They were applying their similar approaches independently in their work, without knowledge of each other, until an ethical crisis involving another astrologer brought them together in 1997 The term itself was used much earlier. It was part of the title of a book by Ray Merriman called Evolutionary Astrology: The Journey of the Soul Through States of Consciousness. Jeff Green & Steven Forrest popularized the term, which is really just one of many names for the long history of psychological and spiritual viewpoints applied to astrology by those that came before them. Some of these people include Madame Blavatsky and others in the Theosophical movement, Alice Bailey, Dane Rudhyar, Stephen Arroyo and Liz Greene.
