Societas Rosicruciana in Anglia (reference article)

This is the Wikipedia article on the Societas Rosicruciana in Anglia, a nineteenth century English Rosicrucian society, an open, crowd edited tertiary reference rather than a scholarly monograph or the society's own primary record. It is cited here only for basic, checkable organizational facts, the nine grade three Order structure and the 1866 to 1867 founding date, and for its later influence on the Hermetic Order of the Golden Dawn, claims that are stable and uncontested in the specialist literature on Western esotericism. Like any Wikipedia article, its content can be edited at any time and it carries no editorial board of its own, so it is not the place to look for a disputed or interpretive claim about the society; a scholarly history of Victorian occultism such as Yates's work on the Rosicrucian current is the stronger source for anything beyond these basic facts.
