On August 26, 1920, the 19th amendment that gave women the right to vote was ratified.
The act was earlier sanctioned on August 18, but the state of Tennessee rescinded its approval.
The official date of the ratification is august 26 when secretary of state Bainbridge Colby signed the proclamation at his home in Washington.
Leaders of the national woman's party protested the fact that no women were present at the signing.
However, members of the woman's party were on watch all night waiting for the arrival of official papers indicating that the required number of states needed for ratification was met.
The long effort to gain voting rights gained speed when Susan B. Anthony convinced a member of congress to introduce a proposed amendment to the constitution.
Some states already allowed women to vote. Wyoming was the first state to do so in 1869. With the ratification of this amendment, all women were legally allowed voting rights.
