Definition
A now-obsolete legal term referring to marriage or sexual union between persons of different races, applied most commonly to relationships between white and Black persons. Anti-miscegenation statutes were laws enacted by many U.S. states that criminalized or voided such marriages and relationships. These statutes were declared unconstitutional by the U.S. Supreme Court in Loving v. Virginia, 388 U.S. 1 (1967), which held that laws restricting marriage on the basis of race violated the Equal Protection and Due Process Clauses of the Fourteenth Amendment. The term carries no operative legal force today and is retained in legal dictionaries solely as a historical reference.
Common Language
Modern common usage (Wiktionary): The mixing or blending of race in marriage or breeding; interracial marriage. Also used more broadly for any mixing considered inappropriate.
Historical common usage (Webster's 1913): A mixing of races; amalgamation, as by intermarriage of black and white.
The common and legal meanings track closely, but the gap that matters is register and implication. Both the historical legal and common definitions treated miscegenation as a neutral descriptive term, but the legal context was anything but neutral — the word existed primarily to name what the law prohibited. Researchers should understand that the term's apparent neutrality in dictionary entries obscures its function as a tool of racial regulation and its fraught political origins. The word was coined as a propaganda device in 1863 and immediately entered the legal vocabulary as statutes proliferated.
Common Confusion
MISCEGENATION vs. AMALGAMATION: Nineteenth-century sources use these terms interchangeably, but amalgamation was the older and more common term before miscegenation was coined in 1863. Researchers working in pre-Civil War materials will encounter amalgamation where later sources use miscegenation. The two terms describe the same phenomenon; the shift in vocabulary reflects the political moment of the coinage, not a change in legal meaning.
MISCEGENATION LAWS vs. MARRIAGE RESTRICTIONS GENERALLY: Anti-miscegenation statutes were a specific category of law targeting racial identity as a bar to marriage. They are distinct from other marriage restrictions (age, consanguinity, capacity) and must be researched as a separate statutory class, typically found under race-based criminal statutes or domestic relations codes in states that enacted them.
Why It Matters in Research
This term is a research trap in two directions — both for what sources say and for what they do not say.
First, the historical legal dictionaries uniformly treated the constitutionality of anti-miscegenation statutes as settled law in favor of the states. Bouvier's cites a string of state court decisions affirming those statutes without qualification. Any researcher relying on pre-1967 secondary sources — including legal dictionaries, treatises, and encyclopedias — will find near-universal endorsement of the validity of these laws. That consensus was overturned entirely by Loving v. Virginia. Any pre-Loving source on this term is not merely dated; it states the law incorrectly as it now stands.
Second, anti-miscegenation statutes varied considerably by jurisdiction in scope, penalty, and definition of racial categories. Some statutes targeted only Black-white marriages; others extended to Asian, Native American, or Filipino persons. The racial classifications used in these statutes were themselves contested and litigated. Researchers examining specific state statutes must attend carefully to how each jurisdiction defined the racial categories at issue, as those definitions were neither uniform nor stable.
Third, the procedural history of how these statutes were applied — through criminal prosecution, civil annulment, inheritance disputes, and citizenship determinations — spreads the relevant case law across criminal, domestic relations, probate, and constitutional law sections of historical digests and reporters. A researcher looking only under "marriage" or "race" may miss significant material.
Finally, the repeal or invalidation of these statutes did not always result in immediate removal from state codes. Some states retained the dead letter language for decades after Loving. Researchers checking state statutory compilations from the 1970s through 1990s may encounter unrepealed provisions that were constitutionally inoperative but formally unexcised.
Historical Dictionary Support
The four source dictionaries agree entirely on the core definition: mixture of races, specifically intermarriage between white and Black persons. Black's (both editions) and Anderson's offer bare definitional statements with no analytical content. Bouvier's is the most substantive, providing the Latin roots, a brief description of the statutory landscape, and a string citation to state cases affirming constitutionality — citations that represent the dominant judicial consensus before federal constitutional doctrine intervened.
What the historical dictionaries uniformly miss is the term's invented and politically charged origin. The word miscegenation was fabricated in an 1863 pamphlet designed to associate the Republican Party with interracial marriage as a political smear. It passed almost immediately into official legal usage as state legislatures encoded the concept in statute. The dictionaries treat it as an ordinary legal term of Latin provenance without flagging this history, which is essential context for understanding both the term's rapid adoption and the ideological work it performed in legal discourse.
Bouvier's reference to "repeated affirmation" of constitutionality is representative of how settled the pre-Loving consensus appeared in legal reference works. No edition of any of these dictionaries in the Law Mind corpus postdates Loving, so none reflects the constitutional reversal. Researchers must supply that correction from primary sources.
Jurisdictional Note
Anti-miscegenation statutes were enacted primarily in Southern and border states, but also in several Western states targeting marriages involving Chinese, Japanese, Filipino, and Native American persons. Northern states generally did not enact such laws, though social and private legal mechanisms achieved similar effects. After Loving v. Virginia, all such statutes became void and unenforceable regardless of whether individual states formally repealed them.
