Mobilizing the Single-Case Study 95
facilitate increased political activism on the part of excluded groups either by se-
riously undermining the stability of the entire political system or by increasing
the political leverage of a single insurgent group” (p. 42). Thus, the opportunities,
as McAdam describes them, can have diverse implications for different excluded
groups. Yet, political opportunities represent just that. They do not guarantee that
mobilization will occur among excluded groups. Thus McAdam turns to the next
facet of the political process model: indigenous organizational strength.
Indigenous organizational strength refers to the resources of the aggrieved
population that allow them to exploit the opportunities afforded them by the
changes in the political opportunity structure. Without these resources, it would be
difficult for a social movement to uphold a sustained effort. Factors that enhance
the indigenous organizational strength within the minority population are the exis-
tence of indigenous group organizations, both formal and informal (e.g., churches,
clubs); an established structure of solidary incentives, which refers to “the myriad
interpersonal rewards that provide the motive force for participation” (p. 45); a
well-developed communication network; and leaders or organizers. All of these
factors serve as resources, from within the excluded group, for the development
(and, presumably, success) of social movements.
The final factor in the political process model is cognitive liberation. Politi-
cal opportunities and indigenous organizational strength yield only the structural
potential for mobilization. What is needed beyond this is the recognition by the
excluded group that their status is not inevitable, that their status as a group has its
origins in the political system, and that their status can be changed (p. 51).
The confluence of these three factors—expanding political opportunities, in-
digenous organizational strength, and cognitive liberation—constitutes the polit-
ical process perspective, which serves as a viable alternative to the classical and
resource mobilization models. Indeed, unlike the alternatives, political process
attempts to account for both internal and external factors that influence social
movement emergence and longevity.
MCADAM’S EMPIRICAL ANALYSIS
Armed with the three alternative perspectives, McAdam undertakes an em-
pirical analysis of the U.S. Civil Rights Movement. In so doing, he focuses on four
historical periods he considers relevant to the movement. The general periodiza-
tion he employs includes the long-term historical background leading up to black
insurgency (1876–1954), the development of black insurgency (1955–1960), the
“heyday” of black insurgency (1961–1965), and the decline of black insurgency
(1966–1970). Throughout the treatment of each of these periods, McAdam is
mindful of the three alternative models available to him, and he is careful to incor–
porate a discussion of how well each accounts for the empirical data. What emerges
from his analysis of the data is an account of insurgency that highlights the
