From the Haudenosaunee women who successfully challenged warfare in the 17th century, to today’s feminist organizers defending democracy, reproductive freedom and civil rights, the struggle for women’s equality has never been a straight line. It is a story of persistence, resistance and collective action spanning centuries.

Compiled by editors at Ms. and researchers from the National Women’s History Alliance, this women’s history timeline traces the interconnected histories of feminism, abolition, labor organizing, civil rights, reproductive justice, LGBTQ+ liberation and democratic participation.

No timeline can fully capture more than 400 years of feminist history, let alone every movement, leader, victory and setback that has shaped the ongoing fight for equality. Rather than offering a comprehensive account, this chronology highlights pivotal moments and turning points that help tell the story of how women have expanded the boundaries of freedom, democracy and human rights in the United States and beyond.

The timeline is part of Ms. magazine’s FEMINIST 250: Founding Feminists project, a multimedia essay series marking the 250th anniversary of the Declaration of Independence by examining the women and feminist movements that have worked to make the nation’s founding promises more fully realized. Through reported features, essays, interviews and historical analysis, FEMINIST 250 explores not only where we have been, but where we must go next to achieve true equality.

FEMINIST 250’s Parts 2 and 3—Feminist Lessons and Feminist Futures—drop this month on MsMagazine.com.
