* American Woman Suffrage Association (AWSA): Founded in 1869, AWSA was the first national suffrage organization in the United States. It was led by prominent suffragists such as Lucy Stone, Julia Ward Howe, and Frances Willard. AWSA focused on lobbying for state suffrage laws and supporting women's rights more generally.
* National Woman's Party (NWP): Founded in 1916, the NWP was a more radical suffrage organization that used tactics such as picketing and hunger strikes to draw attention to the cause of women's suffrage. The NWP was led by prominent suffragists such as Alice Paul, Lucy Burns, and Inez Milholland.
