This study follows the variations in women's nationality rights, citizenship law and immigration policy in the United States during the late Progressive and interwar years, placing the history and impact of ""derivative citizenship"" within the broad context of the women's suffrage movement.;Making use of primary sources, and utilizing documents from many leading women's reform organizations, government agencies, Congressional hearings and federal litigation involving women's naturalization and expatriation, Candice Bredbenner provides a contemporary feminist perspective on key historical, political and legal debates relating to citizenship, nationality, political empowerment, and their implications for women;s legal status in the United States.
