About this source
What it is
This is the House Joint Resolution proposing the 15th Amendment to the U.S. Constitution, submitted to the states in 1868 and ratified in 1870. It is held by the U.S. National Archives. The amendment states that the right to vote cannot be denied on account of race, color, or previous condition of servitude.
Why it matters
To former abolitionists and Radical Republicans, the amendment seemed to fulfill promises made to African Americans after the Civil War, but it granted the vote only to Black men, not to women of any race. Devices like literacy tests and grandfather clauses soon undermined it in practice. Harriet Tubman, who lived through this amendment's passage and its limits, later devoted much of her later life to the women's suffrage movement, campaigning for the right the 15th Amendment did not extend to her.
Look closer
- Who was included, and who was left out, by the wording of this amendment?
- Why might its promise have been undermined within just a few decades?
