For most of history, women have been confined to their households, and to lives without equal rights or equal opportunities. This volume introduces readers to the women of the suffrage movement, the defining movement for women’s rights, especially the right to vote. Primary sources and photographs will show readers firsthand how the challenges and successes of this movement shaped the lives of women across the United States. Readers will also learn about the inequality that still exists for women, and how they can change this injustice in the future.
