vote against anti-suffrage senators up for election in the fall of 1918. After the 1918 election, most members of Congress were pro-suffrage. On May 21, 1919, the House of Representatives passed the amendment, and two weeks later on June 4, the Senate finally followed. With their work done in Congress, the protesters turned their attention to getting the states to ratify the amendment. It was officially ratified on August 26, 1920, shortly after ratification by Tennessee, the thirty-sixth state to do so. The Tennessee legislature ratified the 19th Amendment by the single vote of a legislator (Harry T. Burn) who had opposed the amendment but changed his position after his mother sent him a telegram saying "Dear Son, Hurrah! and vote for suffrage. Don't forget to be a good boy and help Mrs. Catt put the 'rat' in ratification." Popular culture The Silent Sentinels vigil was a key part of the 2004 film Iron Jawed Angels.
