The National American Woman Suffrage Association (NAWSA), founded in 1890, played a crucial role in the fight for women's suffrage in the United States. It united various women's rights groups under a collective cause and focused on advocating for women's right to vote through lobbying, grassroots campaigns, and public education. The association's efforts were instrumental in achieving the 19th Amendment in 1920, which granted women the right to vote. Historically, NAWSA’s significance lies in its role in mobilizing women politically and fostering a broader women's rights movement, influencing social and political change well beyond voting rights.
