Today in History: Women suffrage amendment ratified

Re-Imagining the Suffragettes' Fight for Women's Equality

On August 18, 1920, the 19th amendment to the Constitution was ratified, giving women the right to vote. The amendment came after more than 70 years of struggle for women suffragists.

Tennessee ultimately ratified the amendment, giving the two-thirds majority of state ratification that is required to make a law.

The ratification states: "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." It also says, "Congress shall have power to enforce this article by appropriate legislation."

The beginning of the 20th century came with women having a more prominent role in American society, and the ratification of the 19th amendment was a huge stride in this change.
