After years of the Progressive movement taking hold on the American public, on August 18, 1920, the 19th Amendment to the U.S. Constitution was ratified, guaranteeing the vote to all people, regardless of gender. The purpose of the amendment was to specifically guarantee the right to vote for women, after protests from national women's organizations such as the Silent Sentinels and the National Women's Party. Protestors from the Silent Sentinels petitioned the government for nearly 18 months beginning in 1917, often protesting in front of the White House. Despite initial support from President Woodrow Wilson in favor of the amendment, the legislation would not be passed until late 1920, after repeated attempts at reconsideration from the National Women's Party. The amendment is a significant document in the fight for women's rights.
