Black women fighting for their rights faced unique challenges compared to their white counterparts. Sojourner Truth, abolitionist and women’s rights activist, addresses some of these issues in her famous speech “Ain’t I a Woman?” at the Women’s Convention in Akron, Ohio.

Disagreement over the 15th Amendment, which will ultimately give black men the right to vote, leads to a split. Stanton and Susan B. Anthony found the National Woman Suffrage Association, which opposes the 15th Amendment unless it includes voting rights for women. Lucy Stone, Julia Ward Howe and others who support the 15th Amendment form the American Woman Suffrage Association.

Wyoming becomes a state, making it the first and only state allowing women the right to vote. In 1869, when it was still a U.S. territory, the Wyoming legislature passed a law recognizing women’s rights to vote and hold office.

Shunned by white suffragists, black suffragists worked within their own communities for social progress. Many prominent black women, including Harriet Tubman, Mary Church Terrell and Ida B. Wells Barnett, meet to establish the National Association of Colored Women’s Clubs in Washington, D.C. Their goals include not only suffrage, but also ending racist policies and attacks like lynching, segregation and Jim Crow laws.

A year after it passes in the Senate, the 19th Amendment is ratified; 26 million American women are enfranchised in time for the 1920 election.

However, the Amendment has serious flaws—it doesn’t fully extend to women of color.
