A critical event at Seneca Falls in 1848 was the Seneca Falls Convention, the first women's rights convention in the United States. Organized by Elizabeth Cady Stanton and Lucretia Mott, the convention aimed to address the social, civil, and religious rights of women. The attendees adopted the Declaration of Sentiments, which outlined grievances and called for equal rights for women, including suffrage. This landmark event marked the beginning of the organized women's rights movement in the U.S. and was a significant step towards gender equality, sparking future activism and changing perceptions about women's roles in society.
