The Enforcement Acts were three bills passed by the United States Congress between 1870 and 1871. They were criminal codes which protected African-Americans’ right to vote, to hold office, to serve on juries, and receive equal protection of laws. Passed under the presidency of Ulysses S. Grant, the laws also allowed the federal government to intervene when states did not act to protect these rights. The acts passed following the ratification of the Fourteenth Amendment to the US Constitution, which gave full citizenship to anyone born in the United States or freed slaves, and the Fifteenth Amendment, which banned racial discrimination in voting.
