About 300 activists, including 40 men, gather for a two-day convention in Seneca Falls, N.Y., to strategize how to obtain women’s suffrage nationwide. Elizabeth Cady Stanton and Lucretia Mott, along with 60 other women and 32 men, sign and issue the Declaration of Sentiments and Resolutions, modeled on the Declaration of Independence, which calls for equal treatment of women and men under the law and voting rights for women. Former slave Frederick Douglass addresses the crowd, showing unity between the anti-slavery and women’s rights movements. Two years later, the first National Women’s Rights Convention is held in Worcester, Mass., and attracts more than 1,000 participants.
