Carrie Chapman Catt, American activist, founded the League of Women Voters and International Alliance of Women (died 1947)

Carrie Chapman Catt was an American women's suffrage leader who campaigned for the Nineteenth Amendment to the United States Constitution, which gave U.S. women the right to vote in 1920. Catt served as president of the National American Woman Suffrage Association from 1900 to 1904 and 1915 to 1920. She founded the League of Women Voters in 1920 and the International Woman Suffrage Alliance in 1904, which was later named International Alliance of Women. She "led an army of voteless women in 1919 to pressure Congress to pass the constitutional amendment giving them the right to vote and convinced state legislatures to ratify it in 1920". She "was one of the best-known women in the United States in the first half of the twentieth century and was on all lists of famous American women."

The League of Women Voters (LWV) is a nonpartisan American nonprofit political organization. Founded in 1920, its ongoing major activities include registering voters, providing voter information, boosting voter turnout and advocating for voting rights. In addition, the LWV works with partners for specific campaigns including support for campaign finance reform, women's rights, health care reform and gun control.

The International Alliance of Women is an international non-governmental organization that works to promote women's rights and gender equality. It was historically the main international organization that campaigned for women's suffrage. IAW stands for an inclusive, intersectional and progressive liberal feminism on the basis of human rights and liberal democracy, and has a liberal internationalist outlook. IAW's principles state that all genders are "born equally free [and are] equally entitled to the free exercise of their individual rights and liberty," that "women's rights are human rights" and that "human rights are universal, indivisible and interrelated."
