Women's roles expanded in the 1800s as they became involved in reform movements and the paid workforce. Lucretia Mott and Elizabeth Cady Stanton organized the 1848 Seneca Falls Convention after being barred from speaking at an abolitionist meeting, adopting a Declaration of Sentiments that called for women's rights. This launched the American women's rights movement, led by activists like Susan B. Anthony, who worked for decades to gain women's suffrage.
