“Silent Sentinels” picketed the Wilson White House daily, except Sundays, for two years as part of the campaign to amend the Constitution to allow women to vote in the United States.  The 19th Amendment was certified on Aug. 26, 1920.

The key turning point in public opinion was the “Night of Terror” when prison guards abused women imprisoned for “obstructing sidewalk traffic,” i.e., peacefully demonstrating in favor of the right to vote for women.
