The League of Women Voters is founded in Chicago.

The League of Women Voters (LWV) is a nonprofit organization in the United States that was formed to help women take a larger role in public affairs after they won the right to vote. It was founded in 1920 to support the new women suffrage rights and was a merger of National Council of Women Voters, founded by Emma Smith DeVoe, and National American Woman Suffrage Association, led by Carrie Chapman Catt, approximately six months before the Nineteenth Amendment to the United States Constitution gave women the right to vote. The League of Women Voters began as a "mighty political experiment" aimed to help newly enfranchised women exercise their responsibilities as voters. Originally, only women could join the league; but in 1973 the charter was modified to include men. LWV operates at the local, state, and national level, with over 1,000 local and 50 state leagues, and one territory league in the U.S. Virgin Islands. The league states that it has over 500,000 members and supporters.The League of Women Voter's primary purpose is to encourage voting by registering voters, providing voter information, and advocating for voting rights. In addition, the LWV supports a variety of progressive public policy positions, including campaign finance reform, universal health care, abortion rights, climate change action and environmental regulation, and gun control.
