Democratic transitions represent unique opportunities in which movements of
the poor can coalesce, place their demands on the national agenda, and ins
titutionalise their access to authoritative decision-making centres. The;op
portunities and constraints movements of the poor face during transitions,
however remain little understood and under-theorised. This study develops a
n analytic approach that links national-level democratisation processes to
the local-level movement dynamics that make collective action possible, par
ticularly the creation and reproduction of collective identities and organi
sational structures. The approach theorises how changing elite alliance pat
terns during transition cycles, and redefinition of institutional linkages
that bind state and society, shape the opportunities and constraints moveme
nts face at successive stages of democratic transitions. The utility of thi
s approach is demonstrated by examining the new unionism in rural Brazil, i
n that country's democratic transition during the 1980s.
