The major event involving the gathering of women for social and civil rights in Seneca Falls was the Seneca Falls Convention of 1848. It marked the formal beginning of the women's rights movement in the United States. Organized by Elizabeth Cady Stanton and Lucretia Mott, the convention produced the "Declaration of Sentiments," which outlined grievances and demands for women's equality, including the right to vote. This gathering attracted both women and men who supported the cause, setting the stage for future advocacy for gender equality and inspiring subsequent movements across the nation.
