In later centuries, many esoteric societies have claimed to derive from the original Rosicrucians. The largest and most influential of these societies has been the Hermetic Order of the Golden Dawn, which consisted of several well known members of society, including the British occultist Aleister Crowley. The other is the Rosicrucian Order, A.M.O.R.C, an international, initiatic Fraternity, which involves itself in several educational and cultural activities worldwide.
