How did american women win the fight for suffrage?

Some held them down while the others did the rest. Haha just kidding, here is a long explained answer.

Women in the United States fought a long battle to gain equal voting rights. In the early 1900's, a few western states granted women the right to vote, but many states still remained unmoved. Activists pick up steam as they campaigned all over the country, giving special attention to the states and groups that were the most resistant to women's suffrage. They also aimed at gaining publicity by picketing the White House. Throughout World War I, women made a significant contribution to the war efforts on the home front. They proved their dedication and loyalty to the country. The 19th amendment was ratified on August 26, 1920.

I hope you get a good grade! : 3
