Anti-miscegenation laws were a part of American law since before the United States was established and remained so until ruled unconstitutional in 1967 by the U.S. Supreme Court in Loving v. Virginia. The term miscegenation was first used in 1863, during the American Civil War, by American journalists to discredit the abolitionist movement by stirring up debate over the prospect of black–white intermarriage after the abolition of slavery. In those of the original Thirteen Colonies that became states and enacted such laws, they were enacted as state law in the early 18th century; a century or more after the complete racialization of slavery.
