The event that is marked as the beginning of the American Women’s Rights movement is the Seneca Falls Convention, held in July 1848 in Seneca Falls, New York. Organized by Elizabeth Cady Stanton and Lucretia Mott, the convention convened over 300 activists, both men and women, who gathered to discuss the social, civil, and religious rights of women. The Declaration of Sentiments, which called for gender equality and women’s suffrage, was adopted during this meeting. This pivotal event launched the organized women's rights movement in the United States, setting the stage for future activism and progress toward gender equality.
