The introduction describes in full the comparative politics research design developed by the Research Network on Gender Politics and the State and used to study the role of women's policy agencies as allies or adversaries of women's movement activists in influencing abortion policy and politics. The theoretical foundation integrates several theoretical strands: democratic representation, new institutionalism, and social movement impact. The chapter describes the network's theory of state feminism and provides a primer on the comparative method in policy research. Keywords:abortion policy,
