The significant factor in launching the Suffragette movement was the Seneca Falls Convention, held in 1848 in New York. This first women's rights convention was organized by prominent activists like Elizabeth Cady Stanton and Lucretia Mott, where they presented the "Declaration of Sentiments," asserting women's equality and their right to vote. The convention marked a pivotal moment in the fight for women's suffrage, inspiring future activists to advocate for women's rights and engagement in political life. This laid the groundwork for a broader movement that would persist into the 20th century, culminating in the eventual passage of the 19th Amendment in 1920.
