The article reports the findings of our case study of a social movemen
t organization opposed to the pollution of a river by a paper mill. Us
ing data from participant-observation and archival sources, we analyze
the relationship between elites and non-elites in this community mobi
lization. We find that: (1) mobilization was inhibited for 80 years be
cause of the economic oppression of the region: (2) when a movement or
ganization finally emerged, it was initiated by elites who resisted gr
assroots membership in order to control movement goals and protect the
ir own economic interests, and (3) the elite-sponsored organization de
clined because of internal conflict but generated a new, grassroots or
ganization. Based on our analysis, we conclude that protest and quiesc
ence are cycles in the interaction of elites and non-elites that refle
ct social class conflict.
