Anti-miscegenation laws in the United States

In the United States, many U.S. states historically had anti-miscegenation laws which prohibited interracial marriage and, in some states, interracial sexual relations. Some of these laws predated the establishment of the United States, and some dated to the later 17th or early 18th century, a century or more after the complete racialization of slavery. Nine states never enacted anti-miscegenation laws, and 25 states had repealed their laws by 1967. In that year, the U.S. Supreme Court ruled in Loving v. Virginia that such laws are unconstitutional under the Fourteenth Amendment to the U.S. Constitution.
