Women's Right to Vote: The 19th Amendment
Seventy years after the Seneca Falls Convention, the suffrage amendment reached the floor of Congress during World War I. It passed the House in January 1918 but failed twice in the Senate. After the 1918 elections, the new 66th Congress passed it in both chambers within two weeks.
Resulting law: 19th Amendment to the U.S. Constitution
