When Crane Brinton published his Anatomy of Revolution in 1938, he noted in his bibliography fewer than thirty titles in English that dealt in general terms with revolution. Today a comprehensive listing would include some ten times that number of articles and books, and such proliferation seems likely to continue as scholars go on with their examination of revolution as a theoretical problem and in a number of theoretical and historical contexts. Like Brinton, most have taken a comparative approach, attempting to develop a conceptual framework capable of explaining the nature and the occurrence of all revolutionary movements. More recent studies, however, have moved in the direction of placing revolution in broader contexts.
