One of the leading figures in the women's suffrage movement in the US was Elizabeth Cady Stanton. She was instrumental in organizing the first women's rights convention at Seneca Falls in 1848, where the Declaration of Sentiments was presented. Stanton advocated for women’s voting rights and worked alongside other suffragists like Susan B. Anthony to promote equality and social justice. Her efforts helped lay the groundwork for the women’s suffrage movement and contributed to the eventual passage of the 19th Amendment, which granted women the right to vote.
