The creation of the National American Women Suffrage Movement in 1890 was a critical event in the Women's Suffrage Movement because it unified various women's suffrage organizations across the country under one national organization. This unity and organization allowed for a more coordinated and effective effort to push for women's right to vote on a national level. The National American Women Suffrage Movement played a key role in advocating for the 19th Amendment, which was eventually passed in 1920, granting women the right to vote.
