'Anti-miscegenation laws were a part of American law in some States 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 interracial marriage after the abolition of slavery.[1] 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.[2]
Typically defining miscegenation as a felony, these laws prohibited the solemnization of weddings between persons of different "races" and prohibited the officiating of such ceremonies. Sometimes, the individuals attempting to marry would not be held guilty of miscegenation itself, but felony charges of adultery or fornication would be brought against them instead. All anti-miscegenation laws banned the marriage of whites and non-white groups, primarily blacks, but often also Native Americans and Asians.[3]
In many states, anti-miscegenation laws also criminalized cohabitation and sex between whites and non-whites. In addition, the state of Oklahoma in 1908 banned marriage "between a person of African descent" and "any person not of African descent"; Louisiana in 1920 banned marriage between Native Americans and African Americans (and from 1920–1942, concubinage as well); and Maryland in 1935 banned marriages between blacks and Filipinos.[4] While anti-miscegenation laws are often regarded as a Southern phenomenon, most western and plains states also had anti-miscegenation laws.[citation needed]
Although anti-miscegenation amendments were proposed in United States Congress in 1871, 1912–1913 and 1928,[5][6] a nationwide law against racially mixed marriages was never enacted. Prior to the California Supreme Court's ruling in Perez v. Sharp (1948), no court in the United States had ever struck down a ban on interracial marriage. In 1967, the United States Supreme Court unanimously ruled in Loving v. Virginia that anti-miscegenation laws are unconstitutional.'
