--- - |2 Abstract Despite revolution's recent return to the world stage, the progress of revolutionary theory has markedly stalled. While some have argued that recent work on the 2011 Arab Spring constitutes a new, misguided ‘fifth generation’ of theory, I show this claim to be misplaced, demonstrating the remarkable continuity between foundational fourth‐generation scholarship and present‐day analyses. Furthermore, I critically analyse the theoretical, methodological and professional obstacles which fourth‐generation theory has encountered, concluding that scholars must move beyond the fourth generation if we are to surmount them. Finally, I consider the theoretical, methodological and ethical prospects of a true fifth generation of revolutionary theory. - 'Journal of Historical Sociology, EarlyView. '
