Emergence of the concept
Analyzing protest in U.S. cities in the 1960s, Eisinger (1973) reported that protest occurred most often not in cities whose political systems were fully closed or fully open, but in those mixing openness and closure. In fully closed systems protest is repressed, and in fully open ones demands can be met through institutions. He called this environment the structure of political opportunities. Unlike earlier approaches that explained movements by individual grievances or psychology, the concept directed attention to the political context in which movements operate.
The political process model
Analyzing the U.S. civil rights movement, McAdam (1982) explained that changes such as the decline of the Southern cotton economy, Black migration to the North and the growing electoral importance of Black voters expanded political opportunities, and that these combined with organizational bases such as churches and colleges and a sense that change was possible to fuel the movement's growth. This is called the political process model. Comparing anti-nuclear movements in France, Sweden, the United States and West Germany, Kitschelt (1986) found that movements chose moderate institutional or confrontational strategies depending on whether states had open channels for movement demands and strong capacity to implement policy. Tarrow (2011) explained how such shifts in opportunity produce cycles of protest.
Critiques and developments
The concept has been criticized as so broad that almost anything can be explained as an opportunity. Kurzman (1996) argued that in the 1979 Iranian Revolution the movement spread because people perceived an opportunity even though the state's repressive capacity had not objectively weakened, suggesting that perceived opportunity may matter more than structural opportunity. Meyer and Minkoff (2004) sought to break the concept into measurable components, and Meyer (2004), reviewing the field, concluded that opportunities affect different movement outcomes in different ways. Today it is used alongside resource mobilization theory and framing perspectives to explain movements.
FAQ
- What is political opportunity structure in simple terms?
- It is the idea that social movements need not only grievances but also political openings, such as a government willing to listen or a divided ruling elite, to succeed. Movements become more active when such openings appear.
- What are the limits of political opportunity theory?
- Critics say the concept is so broad that it is unclear what counts as an opportunity. Others note, as in the Iranian Revolution, that how people perceive opportunities may matter more than objective opportunities.
