This dissertation fills a conspicuous gap in the literature on the U.S. woman suffrage movement by developing and testing a model of state woman suffrage success. This model is based on a version of the resource mobilization perspective on social movements which emphasizes the importance of social movement organizations (such as the National American Woman Suffrage Association) as resource-gathering agencies which can exploit the structure of organized politics by mobilizing their own resources and neutralizing those of opponents. Accordingly, this model taps four alternative types of variables used by woman suffrage scholars to explain state success: state political structure, NAWSA mobilization, and liquor and allied interests (opponents of woman suffrage) as well as demographic characteristics.
