Abstract:Popularized by the mass media, Max Weber's sociological concept of charisma now has a demotic meaning far from what Weber had in mind. Weberian charismatic leaders have followers, not fans, although, exceptionally, fans mutate into followers. This essay aims to trace some of the dimensions of Weberian charismatic religious leadership in comparative perspective, medieval and modern. Examples include: preachers, -double charisma,‖ professors, -collective charisma,‖ religious radicals, the economy of charisma, transgressive sexuality, demagogues, living saints.
