State transformation theory links social movements to state policy for
mation processes by focusing on the role of cultural meaning in organi
zed political struggles. Despite a resemblance among concepts and conc
erns, constructionist ideas found in the social problems, social movem
ents, and symbolic politics literatures have Mot been incorporated int
o the theory In this paper I draw on these three literatures to enhanc
e state transformation theory. I emphasize how competing political act
ors struggle to reframe issues that shape subsequent policy. The negot
iation over meanings occurs in a historically contingent process that
depends on shifting definitions, strategic alliances, and organization
al innovation. I apply the expanded theory to the ''trust problem'' in
U.S. history. During the Progressive Era, the ''trust'' was a social
problem at the forefront of public debate. After more than a decade of
struggling, a politically mobilized segment of the dominant class suc
ceeded in reframing the volatile issue into a more palatable and benig
n form that was later institutionalized as federal antitrust policy.
