The Hermetic Order of the Golden Dawn was an influential occult group in late 19th century England, and a major influence on most 20th century magic. Occult luminaries associated with the Order include S. L. MacGregor Mathers, Allan Bennett, and Aleister Crowley, among others; William Butler Yeats and actress Florence Farr were among other members. Those strongly influenced in later incarnatons and descendants included Dion Fortune, Paul Foster Case, and Israel Regardie. Various groups using the teaching and ritual methods of the original Order still exist, sometimes engaging in paper battles over their own and their rivals' legitimacy. The Golden Dawn was a kind of esotericized mixed-gender Freemasonry combining symbols from old grimoires and fresh imaginations, all structured by a version of the Tree of Life derived from Kircher. There were strong areas of common interest and leadership overlap between the Freemasonic/Rosicrucian Societas Rosicruciana in Anglia (SRIA), Theosophy, the Hermetic Brotherhood of Luxor, and the Golden Dawn.
