This article compares the strength, history, and characteristics of pu
blic interest groups in the United States and France. French and Ameri
can public interest groups differ dramatically in their resources, pop
ular support, and in their relations with state agencies. French group
s, dependent on a more powerful central state bureaucracy, are often a
ble to achieve their goals by having them adopted by state elites. Ame
rican organizations, faced with a more diffuse public sector, seek bro
ader access and use a greater diversity of means of influence. They ar
e often less influential, but paradoxically are stronger organizationa
lly because they ave forced to be independent from the state. The diff
ering relations with the state explain the different tactics and organ
izational maintenance strategies pursued by public interest groups in
the two countries. Tight links bind the development of a nation's inte
rest-group system with that of its constitutional structures. An expla
nation of a national interest-group system must include consideration
of the institutional context within which it operates.
