This book offers a history of the twentieth-century feminists who fought for the rights of women, workers, and the poor, both in the United States and abroad. It presents an inspiring look at how US women and their global allies pushed the nation and the world toward justice and greater equality for all. Reclaiming social democracy as one of the central threads of American feminism, the author offers a bold rewriting of twentieth-century feminist history and documents how forces, peoples, and ideas worldwide shaped American politics. She follows egalitarian women's activism from the explosion of democracy movements before World War I to the establishment of the New Deal, through the upheavals in rights and social citizenship at midcentury, to the reassertion of conservatism and the revival of female-led movements today. She brings to life the women who crossed borders of class, race, and nation to build grassroots campaigns, found international institutions, and enact policies dedicated to raising standards of life for everyone. Readers encounter famous figures, including Eleanor Roosevelt, Frances Perkins, and Mary McLeod Bethune, together with less well-known leaders, such as Rose Schneiderman, Maida Springer Kemp, and Esther Peterson. Multiple generations partnered to expand social and economic rights, and despite setbacks, the fight for the many persists, as twenty-first-century activists urgently demand a more caring, inclusive world. Putting women at the center of US political history, this volume reveals the powerful currents of democratic equality that spurred American feminists to seek a better life for all.
