Wallace had 3 interesting articles relating to revitalization movements (anthropology for "social movements"): one on mazeway disintegration, mazeway resynthesis, and revitalization movements (mazeway being culture at the individual level). I'm thinking for it to be a real social movement (sociology for "revitalization movement"), I'm thinking there usually has to be a leader who undergoes some deep, profound transformation in thinking, with followers undergoing similar transformations -- which has to be due to some serious problem in the world that shakes the foundations of their culture (world view and ethos). Otherwise I think it would just a passing fad. For instance, most modern religions started as revitalization movements.
