The Fifteenth Amendment to the United States Constitution prohibits the federal and state governments from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude". It was ratified on February 3, 1870, as the third and last of the Reconstruction Amendments.
In the final years of the American Civil War and the Reconstruction Era that followed, Congress repeatedly debated the rights of the millions of black former slaves. By 1869, amendments had been passed to abolish slavery and provide citizenship and equal protection under the laws, but the narrow election of Ulysses S. Grant to the presidency in 1868 convinced a majority of Republicans that protecting the franchise of black voters was important for the party's future. After rejecting more sweeping versions of a suffrage amendment, Congress proposed a compromise amendment banning franchise restrictions on the basis of race, color, or previous servitude on February 26, 1869. The amendment survived a difficult ratification fight and was adopted on March 30, 1870.
