Loving v. Virginia was a 1958 Supreme Court case that struck down state laws banning interracial marriage in the United States.
With the help of the American Civil Liberties Union (ACLU), Richard and Mildred Loving, a white man and Black woman whose marriage was deemed illegal according to Virginia state law, appealed to the U.S. Supreme Court.
The Supreme Court ruled unanimously that “anti-miscegenation” statutes were unconstitutional under the 14th Amendment.
