In France in the later 18th century there arose the motif of secret societies of sapphists "more mysterious than the Freemasons" that existed to initiate women into lesbianism, to serve the pleasures of their members, and to achieve unsavory political ends. The existence of these formal organizations was purely fictitious. Their alleged membership typically included unpopular political and social figures. And their alleged purpose was ostensibly to disrupt the heterosexual organization of society, as an allegory for disrupting other social frameworks.
