In Washington state, various woman suffrage organizations had been working to win votes for women since the 1880s, with some successes, later repealed. Finally, on November 8, 1910, Washington state's male electorate granted women the franchise by an overwhelming majority, breaking a 14-year gridlock in the national crusade and making Washington the fifth state in the United States where women could vote.
Washington's enactment of woman suffrage opened the floodgates for other Western states, which quickly followed suit. To counter strong resistance in the older and more entrenched East and South, the national crusade escalated its demand for an amendment to the U.S. Constitution. Washington women remained involved in the national crusade until the passage of the 19th Amendment to the constitution in 1920.
The 19th Amendment
The 19th Amendment to the Constitution of the United States of America reads:
The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex. Congress shall have the power to enforce this article by appropriate legislation.
The 19th Amendment was proposed by resolution of the U.S. Congress on June 4, 1919. It was ratified by more than three-fourths of the states, and declared ratified in a proclamation of the U.S. Secretary of State on August 26, 1920, on which day it became the law of the land.
