Elizabeth Cady Stanton was a prominent American suffragist, social activist, and leading figure of the early women's rights movement. Born in 1815, she is best known for organizing the first women's rights convention in Seneca Falls, New York, in 1848, where she presented the Declaration of Sentiments, advocating for women's equality and suffrage. Stanton worked tirelessly alongside other activists, including Susan B. Anthony, to challenge societal norms and fight for women's rights. Her writings and speeches played a crucial role in shaping the feminist movement, and her legacy continues to inspire generations of advocates for gender equality.
