Black suffrage in the United States

The history of black suffrage in the United States, or the right of African Americans to vote in elections, has had many advances and setbacks. Prior to the Civil War and the Reconstruction Amendments to the U.S. Constitution, some Black people in the United States had the right to vote, but this right was often abridged or taken away. After 1870, Black people were theoretically equal before the law, but in the period between the end of Reconstruction era and the passage of the Civil Rights Act of 1964 this was frequently infringed in practice.
