Definition
White slavery is a legal term of art, now largely archaic in formal usage, referring to the systematic enticement, procurement, or coercion of women and girls into prostitution or other forms of sexual exploitation. The term carried a specific statutory meaning in early twentieth-century American federal law, centered on the Mann Act of 1910 (officially the White Slave Traffic Act), which criminalized the interstate or foreign transportation of women and girls for immoral purposes. In legal usage, the term encompassed both organized commercial vice networks and individual acts of procurement, with particular emphasis on deception and compulsion as the means of enslavement.
The term should be understood today primarily as a historical legal category rather than an active term of art. Modern law addresses the same conduct under the headings of human trafficking, sex trafficking, and forced prostitution.

Common Language
Modern common usage (Wiktionary): Sexual slavery, particularly the forced prostitution of women of European ancestry; or slavery and slave trading where the victims were of European ancestry.
Historical common usage (Webster's 1913): Webster's 1913 does not include a discrete entry for "white slavery," reflecting that the term had not yet fully solidified in popular or legal usage at the time of that edition's compilation.
The gap between common and legal meaning is historically significant. In popular usage, "white slavery" was understood in racial terms, contrasting with chattel slavery by foregrounding the European ancestry of victims. The legal meaning, as developed by federal statute and courts, was functionally narrower: it referred specifically to organized prostitution and procurement rings, without requiring a racial element as a formal legal ingredient. Courts and federal prosecutors applied the Mann Act to conduct involving women of any background. The racial overtones of the common term persisted in public discourse and shaped the political framing of reform legislation, but they did not constitute an element of the offense.

Common Confusion
WHITE SLAVERY vs. HUMAN TRAFFICKING: Modern researchers must resist the assumption that white slavery and human trafficking are interchangeable terms. White slavery, as used historically, was almost entirely oriented toward sexual exploitation of women and girls. Human trafficking is a broader contemporary category that encompasses labor trafficking, debt bondage, and exploitation of men, women, and children across a range of industries. The Mann Act—the primary legislative artifact of white slavery law—has been substantially amended and now coexists with later comprehensive trafficking statutes. Research into trafficking law that stops at Mann Act sources will miss the modern statutory framework entirely.
WHITE SLAVERY vs. CHATTEL SLAVERY: The racial etymology of the term creates a persistent confusion in historical research. White slavery was not a legal euphemism for any form of racial bondage. It was a reformist and legislative label attached to prostitution and procurement, chosen precisely to generate moral outrage by invoking the horror of antebellum slavery. The Thirteenth Amendment jurisprudence that dismantled chattel slavery is related constitutional background, but white slavery prosecutions were primarily statutory, not constitutional.

Why It Matters in Research
Researchers encounter this term most often in three distinct contexts, each requiring different navigation strategies.
First, Mann Act research. The White Slave Traffic Act of 1910 generated a large body of federal case law running from the early twentieth century through the mid-century. The term "white slavery" appears extensively in case reporters, congressional records, and law review commentary from this period. Researchers should be aware that the Mann Act was amended significantly—first in 1978 to remove gender-specific language, and again in 1986—meaning that cases decided under different versions of the statute may not be reliable guides to current law.
Second, progressive-era reform literature. The period from roughly 1900 to 1920 produced a substantial body of reform pamphlets, vice commission reports, and popular legal commentary using "white slavery" as a central organizing term. This material is legally significant because it shaped the legislative history of the Mann Act, but it is also saturated with racial, nativist, and moral-panic framing that does not map cleanly onto legal doctrine. Researchers using this literature to reconstruct legislative intent should read it critically.
Third, Thirteenth Amendment and trafficking scholarship. Contemporary constitutional scholars examining the Thirteenth Amendment's reach—particularly the abolition of badges and incidents of slavery—sometimes engage with white slavery cases as precedent or historical analog. The connection is legitimate but requires care: the white slavery framework was largely statutory, and treating it as settled constitutional doctrine requires attention to which courts were speaking and in what capacity.
The Bouvier citation to 227 U.S. 308 refers to Hoke v. United States (1913), in which the Supreme Court upheld the constitutionality of the Mann Act under the Commerce Clause. That case remains the foundational constitutional anchor for the white slavery statutory framework.

Historical Dictionary Support
Bouvier's Law Dictionary defines white slavery as "systematic enticement to and the enslavement in prostitution and debauchery of women, and, more insistently of girls," citing Hoke v. United States. Bouvier's definition is notable for what it emphasizes: systematicity and enticement, not mere isolated acts, and a particular insistence on the vulnerability of girls as opposed to adult women. This framing reflects the reform-era concern with organized vice networks rather than individual moral failing.
Bouvier's is the only historical dictionary source available for this entry. The absence of the term from earlier dictionaries is itself informative: white slavery as a legal category emerged almost entirely in the period between 1890 and 1920, making it invisible to lexicographers working before that period. Researchers relying on eighteenth- or nineteenth-century legal dictionaries for this term will find nothing, not because the underlying conduct was unknown, but because the legal category had not yet crystallized.
What Bouvier's does not address: the racial dimension of the term's construction, the Mann Act's subsequent amendment history, and the relationship between white slavery law and later trafficking frameworks. These silences are characteristic of a dictionary entry that captures doctrine at a particular moment without tracing its evolution.

Jurisdictional Note
White slavery prosecutions under the Mann Act were and remain exclusively a matter of federal law, grounded in the Commerce Clause. State-level prostitution and procurement law developed in parallel but used different terminology and different doctrinal frameworks. Researchers working in state sources will rarely encounter "white slavery" as a formal legal category; analogous state offenses appear under headings such as pandering, procurement, and compelling prostitution.
