[email protected] Abstract Some theories of revolution deny an independent role for ideology in the making of rev- olutions, whereas others grant it an indispensable role. I investigate the role of ideology in the Iranian Revolution by focusing on two periods of Iranian history that witnessed popular uprising: the early 1960's and the late 1970's. While the former uprising was aborted, the latter led to the Iranian Revolution. Contrasting these periods, I argue that the structural and non-agency process factors underwent the same dynamic in both periods, and hence are not sufficient to explain the variation in outcome. I propose that the change in the oppo- sition's ideology accounts for this variation. To establish the causal link, I investigate this ideological change, tracing its role in the actors' decision-making processes. I argue that: (1) Khomeini's theory of Islamic state expanded the set of alternatives to the status quo theory of state, and changed the Islamic opposition's \calculus of protest"; (2) an ideological change is an intellectual innovation/shock, the timing of which is intrinsically uncertain. Therefore, integrating ideology to the theory enhances its explanatory power; (3) an ideological change can serve as an observable intermediate variable that mediates the effect of unobservable cumulative and/or threshold processes.
