"By 1916, almost all of the major suffrage organizations were united behind the goal of a constitutional amendment. When New York adopted woman suffrage in 1917 and President Wilson changed his position to support an amendment in 1918, the political balance began to shift."
"On May 21, 1919, the House of Representatives passed the amendment, and 2 weeks later, the Senate followed. When Tennessee became the 36th state to ratify the amendment on August 18, 1920, the amendment passed its final hurdle of obtaining the agreement of three-fourths of the states. Secretary of State Bainbridge Colby certified the ratification on August 26, 1920, changing the face of the American electorate forever."
"The campaign for woman suffrage was long, difficult, and sometimes dramatic; yet ratification did not ensure full enfranchisement. Decades of struggle to include African Americans and other minority women in the promise of voting rights remained. Many women remained unable to vote long into the 20th century because of discriminatory state voting laws."
