Women first organized and collectively fought for suffrage at the national level in July of 1848. Suffragists such as Elizabeth Cady Stanton and Lucretia Mott convened a meeting of over 300 people in Seneca Falls, New York. In the following decades, women marched, protested, lobbied, and even went to jail. By the 1870s, women pressured Congress to vote on an amendment that would recognize their suffrage rights. This amendment was sometimes known as the Susan B. Anthony amendment and became the 19th Amendment.
The amendment 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."
As the capital of the United States of America and the seat of the federal government, the District of Columbia was an ideal place to stage marches, parades, and protests. Organizations like the National Woman’s Party had a national headquarters in DC with local and regional chapters throughout the country. Having a headquarters in the capital allowed women to gather and plan demonstrations and pickets in places like in front of the White House or Capitol Building where politicians and government officials could see.
After decades of arguments for and against women's suffrage, Congress finally approved the 19th Amendment in 1919. After Congress passed the 19th Amendment, at least 36 states needed to vote in favor of it for it to become law.
this process is called ratification. In August of 1920, 36 states ratified the 19th Amendment, ensuring that the right to vote could not be denied by any state based on sex.
But the ratification of the 19th Amendment impacted women differently based on where they lived. Since Washington, D.C. is a federal district and not a state, it could not participate in the ratification process. Women in the District of Columbia were not able to vote after the amendment was ratified in 1920, but neither were men.
The United States Constitution, in Article I, Section 8, states that "Congress shall have Power To… exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States." Until the 1870s, District residents had some kind of elected local government, but Congress abolished it in 1874. From 1874 until 1967, a presidentially appointed Board of Commissioners governed Washington. President Johnson changed the structure to a mayor and city council in 1967, but the positions were still appointed rather than elected. The next year, DC residents were able to vote for school board members. In 1973, Congress passed a Home Rule Act for D.C. which established elected positions for the mayor and council as well as a non-voting delegate in the U.S. House of Representatives. Congress still has the power to impose laws on Washington, D.C. or to veto any laws passed by the D.C. Council.
It took another constitutional amendment, the 23rd Amendment ratified in 1961, for District of Columbia residents to win the right to vote for President and Vice President. A constitutional amendment establishing full representation in the Congress for Washington, D.C. passed in 1978 but was not ratified by enough states. Proposals for D.C. statehood have so far failed to pass Congress.
