Research on social movements has usually addressed issues of movement
emergence and mobilization, yet has paid less attention to their outco
mes and consequences. Although there exists a considerable amount of w
ork on this aspect, little systematic research has been done so far. M
ost existing work focuses on political and policy outcomes of movement
s, whereas few studies address their broader cultural and institutiona
l effects. Furthermore, we still know little about the indirect and un
intended consequences produced by movements. Early studies have dealt
with the effectiveness of disruptive and violent actions and with the
role of several organizational variables for movement success. More re
cently, scholars have begun to analyze movement outcomes in their poli
tical context by looking at the role of public opinion, allies, and st
ate structures. A comparative perspective promises to be a fruitful av
enue of research in this regard.
