Spence also proposes a sub-category of "Elite Secret Societies" (composed of high-income or socially influential people), and notes that secret societies have a frequent if not universal tendency towards factionalism, infighting and claiming origins older than can be reliably documented. Spence's definition includes groups traditionally thought of as secret societies (Freemasons and Rosicrucians) and other groups not so traditionally classified such as certain organized crime cabals (the Mafia), religious groups (Order of Assassins and Thelema) and political movements (Bolsheviks and Black Dragon Society).
