Anti-miscegenation laws were state statutes that prohibited marriage, and often sexual relationships, between people of different races. The first appeared in colonial Maryland in 1664, and over the next three centuries more than 40 states enacted some version. They imposed criminal penalties, voided marriages performed elsewhere, and stripped interracial families of inheritance and legitimacy rights. The Supreme Court struck down every remaining law in its unanimous 1967 ruling in Loving v. Virginia, holding that marriage is a fundamental right that cannot be restricted by race.
Where the Laws Came From
Maryland’s colonial legislature passed the first anti-miscegenation statute in North America on September 20, 1664. It targeted marriages between free white women and enslaved Black men, declaring that any children of such unions would themselves be enslaved and that the women would be bound as indentured servants to their husband’s enslaver for the duration of the husband’s life. The design was punitive by intent: make the consequences severe enough that the relationships would not form.
Virginia followed in 1691, and by the American Revolution most colonies had similar bans. Some northern states repealed early — Pennsylvania in 1780, Massachusetts in 1843, Iowa in 1851 — but across the South and much of the West the laws stayed on the books well into the twentieth century. By the mid-1900s, roughly 30 states still actively enforced some form of interracial marriage prohibition.
How States Defined Race
Enforcing the bans required legal definitions of race, and those definitions varied sharply between states. Virginia is the clearest example of how far legislatures pushed. In 1785, Virginia classified a person as “mulatto” if they had one-quarter or more African ancestry. By 1910, the threshold had dropped to one-sixteenth. In 1924, Virginia’s Racial Integrity Act adopted what became known as the one-drop rule, defining a white person as someone “who has no trace whatsoever of any blood other than Caucasian.”1Library of Virginia. The New Virginia Law To Preserve Racial Integrity, March 1924
The 1924 law included one carve-out: people with less than one-sixty-fourth Native American ancestry could still be classified as white, a provision written to accommodate prominent Virginia families who claimed descent from Pocahontas. Marriage license applicants had to identify their race as “white,” “colored,” or “mixed,” and county clerks cross-referenced birth certificates and genealogical records to verify those claims.1Library of Virginia. The New Virginia Law To Preserve Racial Integrity, March 1924
Other states used fractional blood-quantum thresholds, often classifying anyone with one-eighth or more African ancestry as non-white. What remained constant was that a person’s race was determined by bureaucratic records and ancestral arithmetic, and that determination controlled whether a state would issue a marriage license.
Who the Laws Targeted
The best-known versions of these statutes targeted Black-white marriages, but many states extended the bans much further. At least fifteen states prohibited marriages between white people and those of Asian descent. Several western states used the archaic legal category “Mongolian” to sweep Chinese, Japanese, and Korean people under a single prohibition. Others banned marriages with Native Americans, Native Hawaiians, or people classified as “Malays,” a term aimed at Filipino immigrants.
The targeted groups shifted with immigration patterns. When Filipino laborers arrived in California in large numbers during the 1920s and 1930s, the state amended its statute in 1933 to add “members of the Malay race” to the list of people barred from marrying white residents. Montana and Nebraska specifically named “Chinese” and “Japanese” persons in their statutes rather than using broader racial categories. Virginia’s Racial Integrity Act took the widest approach, banning white people from marrying any “colored” person at all.
Criminal Penalties
Violating an anti-miscegenation law carried serious consequences. Virginia classified interracial marriage as a felony punishable by one to five years in the state penitentiary.2Supreme Court of the United States. Loving v. Virginia, 388 U.S. 1 Other states imposed a mix of imprisonment and fines. Some treated the offense as a misdemeanor carrying months in jail; others imposed multi-year prison sentences. Fines often ran into hundreds of dollars, months of wages for working-class families of the time.
Couples who tried to evade a home-state ban by marrying elsewhere generally could not escape prosecution. Most states with these laws included provisions declaring that any marriage performed elsewhere was void if it would have been illegal at home. Courts treated the disability as personal to the couple, following them regardless of where the ceremony took place. A couple could hold a valid marriage certificate from another state and still be prosecuted for unlawful cohabitation or “lewd and lascivious” conduct once they returned.
Prosecutions often began with anonymous tips from neighbors, landlords, or co-workers. Investigators then dug into ancestry through birth records and genealogical testimony. A conviction carried consequences well beyond the sentence: a criminal record made housing and employment harder to find, and the social stigma isolated many couples from their communities.
Effects on Property, Inheritance, and Children
Because these laws declared interracial marriages void, they stripped away every legal protection marriage provided. A surviving partner had no spousal inheritance rights. If one partner died, the other could be treated as a legal stranger for purposes of property, life insurance, and estate claims. In an era when marriage was the primary vehicle through which families built and transferred wealth, that left surviving partners and their families financially exposed.
Children faced parallel consequences. Because their parents’ marriages were void, children of interracial couples were classified as illegitimate. Illegitimate children were denied the right to inherit from their fathers in most jurisdictions, and they generally had no legal claim on their fathers for support. The economic effects concentrated across generations in communities already marginalized by racial discrimination.
Why the Laws Survived So Long: Pace v. Alabama
For most of their history, these statutes faced little serious legal challenge. The Supreme Court’s 1883 decision in Pace v. Alabama gave them a constitutional foundation that held for nearly a century. The case involved an Alabama law that imposed harsher penalties for adultery and fornication when the parties were of different races.3Justia. Pace v. Alabama, 106 U.S. 583 (1883)
The Court upheld the law under what became known as the equal application theory. Because both the white person and the Black person faced the same punishment, the Court reasoned, no racial discrimination had occurred. The penalty was “directed against the offense designated, and not against the person of any particular color or race.”3Justia. Pace v. Alabama, 106 U.S. 583 (1883) Symmetrical punishment, in other words, satisfied equal protection. That logic became the main legal defense for anti-miscegenation laws for the next eight decades, and courts treated marriage as a state-controlled institution rather than an individual right.
The First Crack: Perez v. Sharp
The consensus began to fracture in 1948 when the California Supreme Court struck down that state’s anti-miscegenation statute in Perez v. Sharp. The court held that the law violated both the equal protection and due process guarantees of the U.S. Constitution by restricting marriage on the basis of race.4Justia Law. Perez v. Sharp, 32 Cal. 2d 711
The California court’s reasoning anticipated much of what the U.S. Supreme Court would eventually adopt. It recognized marriage as a fundamental right, declared that legislation restricting that right “must be based upon more than prejudice,” and concluded that racial segregation in marriage “necessarily impairs the right to marry.”4Justia Law. Perez v. Sharp, 32 Cal. 2d 711 The ruling also found the racial categories in the statute too vague to constitute valid regulation. Over the next two decades, roughly a dozen more states repealed their bans through legislative action. Sixteen states still had them when the definitive challenge reached the Supreme Court.
Loving v. Virginia
In June 1958, Mildred Jeter, a Black woman, and Richard Loving, a white man, traveled from their home in Virginia to Washington, D.C., to get married. They returned to Caroline County, Virginia, where police raided their bedroom in the middle of the night and found their marriage certificate hanging on the wall. They were indicted under Virginia’s Racial Integrity Act.5Justia U.S. Supreme Court Center. Loving v. Virginia, 388 U.S. 1 (1967)
The Lovings pleaded guilty and were sentenced to one year in jail. The trial judge suspended the sentence on the condition that they leave Virginia and not return together for twenty-five years.6Supreme Court of the United States. Loving v. Virginia, 388 U.S. 1 The judge wrote in his opinion that “Almighty God created the races white, black, yellow, malay and red” and placed them on separate continents, and that “the fact that he separated the races shows that he did not intend for the races to mix.” The Lovings moved to D.C. and eventually challenged their convictions. The case reached the Supreme Court in 1967.
The Court ruled unanimously that Virginia’s statutes violated both the Equal Protection Clause and the Due Process Clause of the Fourteenth Amendment. Chief Justice Earl Warren wrote that the laws had no legitimate purpose “independent of invidious racial discrimination” and existed solely to maintain white supremacy.5Justia U.S. Supreme Court Center. Loving v. Virginia, 388 U.S. 1 (1967) The decision dismantled the equal application theory from Pace v. Alabama, holding that identical penalties on both parties did not cure the underlying racial classification.
Warren also framed marriage in language that would outlast the case itself. “The freedom to marry has long been recognized as one of the vital personal rights essential to the orderly pursuit of happiness by free men,” he wrote. “Under our Constitution, the freedom to marry, or not marry, a person of another race resides with the individual and cannot be infringed by the State.”6Supreme Court of the United States. Loving v. Virginia, 388 U.S. 1 That characterization of marriage as a basic civil right became the foundation for later challenges to marriage restrictions, including the Supreme Court’s 2015 ruling in Obergefell v. Hodges.
Why the Language Stayed on the Books
Loving made every remaining anti-miscegenation law in the country unenforceable overnight. Removing the language from state codes was a slower process. Sixteen states still had these statutes on their books at the time of the ruling.5Justia U.S. Supreme Court Center. Loving v. Virginia, 388 U.S. 1 (1967)
Most states acted within a few years — Virginia, Florida, Missouri, Oklahoma, and West Virginia all repealed by 1969. Others moved much more slowly. Delaware did not formally repeal until 1986. Mississippi waited until 1987. Several states had anti-miscegenation language embedded in their state constitutions, which required voter referendums to remove. South Carolina voters approved a constitutional amendment removing the ban in 1998. Alabama became the last state to act when voters approved a similar amendment in 2000.
The late repeals were administrative. The laws had been legally dead since 1967, and no one could be prosecuted under them. But the fact that the language remained in official state constitutions for more than three decades after the Supreme Court struck it down shows how deeply these statutes were woven into state legal frameworks, and how much slower institutional change moved than constitutional principle.
