The Alpha et Omega is an occult order, initially named the Hermetic Order of the Golden Dawn, co-founded in London, England by Samuel Liddell MacGregor Mathers in 1888. The Alpha et Omega was one of four daughter organisations into which the Hermetic Order of the Golden Dawn fragmented, the others being the Stella Matutina; the Isis-Urania Temple led by A.E. Waite and others; and Aleister Crowley's A∴A∴.Following a rebellion of Adepts in London and an ensuing public scandal which had brought the name of the Golden Dawn into disrepute, Mathers renamed the branch of the Golden Dawn remaining loyal to his leadership to "Alpha et Omega" sometime between 1903 and 1913. "The title was usually abbreviated as A.O." and according to some sources its full name was "Rosicrucian Order of Alpha et Omeg
