“In many states, anti-miscegenation laws also criminalized cohabitation and sex between Whites and non-Whites. In addition, 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 to 1942, concubinage as well); and Maryland in 1935 banned marriages between Black people and Filipinos.[6] While anti-miscegenation laws are often regarded as a Southern phenomenon, most states of the Western United States and the Great Plains also enacted them.
Although anti-miscegenation amendments were proposed in United States Congress in 1871, 1912–1913 and 1928,[7][8] a nationwide law against mixed-race 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 (the Warren Court) unanimously ruled in Loving v. Virginia that anti-miscegenation laws are unconstitutional. After Loving, the remaining state anti-miscegenation laws were repealed; the last state to repeal its laws against interracial marriage was Alabama in 2000.”
