With the financial backing of Mrs. Havemeyer and others like her, Ms. Paul launched an increasingly confrontational series of protests that agitated for the right to vote. Paul's most famous efforts were the 1913 National Suffrage Parade, which produced a riot on the eve of President Woodrow Wilson's first inauguration and, as a member of the Silent Sentinels, the wartime picketing of the White House. During the latter, Paul used portions of the President's speeches heralding the defense of democracy in Europe which she masterfully contrasted with the denial of liberty to American women. When jailed for obstructing traffic in 1917, she hunger struck, bringing tremendous pressure to bear on the Congress and Wilson Administration. The Nineteenth Amendment, which extended voting rights to women, was debated by Congress, gained the necessary 2/3 votes in 1919, was sent to the states for ratification, and gained the necessary 3/4 of states ratifying in 1920.
