Definition
1. (Criminal law) A serious felony offense consisting of unlawful sexual intercourse committed by force and without the victim's consent. At common law, the offense was defined narrowly: carnal knowledge (penile-vaginal penetration) of a woman by a man, accomplished forcibly and against her will. Modern statutory law has substantially expanded this definition in most U.S. jurisdictions to include oral and anal penetration, penetration by objects, offenses committed by any person against any person regardless of gender, and acts committed against victims who are incapacitated, intoxicated, or otherwise unable to consent. Marital rape, once categorically excluded from the offense, is now recognized as criminal in all U.S. jurisdictions.
2. (Administrative geography, historical English law) A territorial subdivision of a county, ranking between a shire and a hundred. Used historically in Sussex, England, which was divided into six rapes rather than hundreds. This meaning is entirely obsolete in legal practice and appears only in historical sources.

Common Language
Modern common usage (Wiktionary): The act of forcing sex upon another person without their consent or against their will; originally coitus forced by a man on a woman, but now generally any sex act forced by any person upon another person, regardless of gender.
Historical common usage (Webster's 1913): Webster's 1913 does not define the criminal or geographic term at all — its entry addresses only the agricultural product (grape refuse used in winemaking), which shares the spelling by coincidence of etymology.
The modern colloquial meaning and the modern legal meaning have largely converged, but a meaningful gap remains: common usage treats rape as any non-consensual sexual act, while legal definitions vary significantly by jurisdiction in what conduct they reach, what mental state they require of the perpetrator, what degree of force or incapacity must be shown, and what procedural rules govern prosecution. Researchers should not assume that a colloquial description of conduct as "rape" maps to any specific statutory offense.

Common Confusion
RAPE vs. SEXUAL ASSAULT: These terms are frequently used interchangeably in common speech but are legally distinct in most modern codes. Rape typically refers to a specific act involving penetration. Sexual assault is a broader statutory category that may include rape as its most serious degree but also encompasses non-penetrative contact offenses. In jurisdictions that have consolidated their sex offense statutes, the standalone offense of "rape" may no longer exist as a named crime, replaced by graded degrees of sexual assault. Researchers working across time periods or jurisdictions must determine which statutory scheme was in effect.
RAPE vs. STATUTORY RAPE: Common-law rape requires proof of force and non-consent. Statutory rape is a separate offense based on the victim's age, not on the presence or absence of force — the law presumes incapacity to consent below the age of consent. The two offenses can coexist on the same facts but have different elements, different defenses, and often different penalties. See the separate dictionary entry for STATUTORY RAPE.

Core Elements
Under the traditional common-law formulation, four elements were required:
1. Carnal knowledge — penetration, however slight, of the female sex organ by the male sex organ. Emission was not required. This element was the outer boundary of the offense at common law; acts not meeting this definition, however violent, were not rape.
2. Of a woman — the victim was legally required to be female. A man could not be the victim of rape at common law; he could be the victim of sodomy, which was a separate offense.
3. By a man — the perpetrator was required to be male. A woman could be an accessory or principal in the second degree but could not, at common law, be the direct perpetrator.
4. Forcibly and against her will — both force by the perpetrator and non-consent by the victim were required. Courts historically required resistance by the victim to corroborate non-consent, a requirement that modern law has broadly rejected. The "against her will" element generated the most litigation and the most doctrinal refinement.
Modern statutes vary substantially from this framework. Many replace the force requirement with a consent-based standard, expand the physical acts covered, remove the gender restrictions, and eliminate the corroboration and resistance requirements entirely.

Recognized Forms
/SUBTYPES
Forcible rape: The core common-law offense; sexual penetration accomplished by force, threat of force, or coercion.
Statutory rape: Sexual intercourse with a person below the age of consent, regardless of force or consent. Treated as a strict liability or near-strict liability offense in most jurisdictions.
Acquaintance rape / date rape: Descriptive terms (not formal legal categories) for forcible rape committed by someone known to the victim. These terms emerged prominently in legal discourse during the late twentieth century as courts and legislatures addressed the gap between formal law and prosecutorial practice.
Spousal / marital rape: Sexual assault committed by a spouse. At common law, marriage was treated as irrevocable consent, creating a complete marital exemption. All U.S. jurisdictions have now abolished or substantially curtailed this exemption, though some retain procedural distinctions.

Why It Matters in Research
The definition of rape in historical sources is not the definition in effect today, and researchers working with primary sources across time periods must treat the term with care. Three specific traps arise frequently.
First, the gender restriction. Historical sources uniformly define rape as an act by a man upon a woman. Researchers examining cases or statutes from before the modern reform era will find this restriction embedded throughout. Modern sources have abandoned it, but the distinction affects how historical materials must be read and how pre-reform precedent applies (or does not apply) to modern prosecutions.
Second, the force and resistance requirements. Historical courts required active physical resistance by the victim to prove non-consent, a doctrine now broadly discredited. Opinions applying the resistance requirement are still on the books in many jurisdictions and can appear in searches without obvious flags indicating that they reflect superseded doctrine. Any historical case analysis that relies on victim conduct must account for this shift.
Third, the marital exemption. The common-law rule that a husband could not be guilty of raping his wife survived in statutory form in many U.S. jurisdictions well into the second half of the twentieth century. Researchers examining statutes, pattern jury instructions, or secondary sources from this period must verify whether the exemption was in force at the relevant time.
Researchers also need to track the shift from "rape" statutes to consolidated "sexual assault" or "criminal sexual conduct" statutes. Many jurisdictions restructured their sex offense codes in the 1970s and 1980s, eliminating rape as a named offense and replacing it with graded degrees of sexual assault. Searching only for "rape" in statutory databases may miss controlling authority if the governing statute uses different terminology.
The rape shield rules present a distinct research challenge. Federal Rules of Evidence 412–415, and their state analogs, govern the admissibility of a victim's prior sexual conduct and a defendant's prior sex offense history. These rules affect what evidence appears in the record, how opinions are reasoned, and what arguments counsel may make. Evidence research in sex offense cases must begin with the applicable shield rules. See the encyclopedia entry on Sex Offense Cases (Rules 412–415) for navigational guidance.

Historical Dictionary Support
The historical dictionaries agree on the core criminal definition — carnal knowledge of a woman forcibly and against her will — and on its status as a felony. Black's (both editions), Anderson's, Burrill's, and Rapalje & Lawrence all track this formulation closely, drawing on Blackstone's Commentaries (4 Bl. Comm. 210) as the primary authority.
Anderson's is the most candid about the definition's limitations, noting that "it is not easy to express in one definition all the refinements of the decisions upon this subject, especially as statutory definitions differ, and peculiar cases may be stated." This acknowledgment is historically significant: it confirms that even in the classical period, courts found the common-law definition insufficient to cover the range of conduct being litigated.
Burrill's and Black's both include the geographic meaning (the Sussex territorial division) alongside the criminal definition. This dual entry reflects the term's genuine polysemy in English legal tradition and is worth noting for researchers working in historical English law materials where the word may appear in a non-criminal context.
All historical sources limit the offense to male perpetrators and female victims, and none addresses the marital exemption critically — they reflect rather than interrogate the received doctrine. The corroboration and resistance requirements, while extensively litigated in historical case law, receive little structural analysis in any of the dictionary sources. Researchers needing doctrinal depth on those questions must go to the treatise literature and case reporters directly.
Rapalje & Lawrence alone notes the capital punishment dimension, observing that rape was punishable by death in some American jurisdictions at the time of writing — a fact with significant constitutional history, as the U.S. Supreme Court later held in Coker v. Georgia (1977) that the death penalty for rape of an adult woman violates the Eighth Amendment.

Jurisdictional Note
Rape law is almost entirely a matter of state statutory definition in the United States, and definitions vary considerably. Some states retain a standalone rape statute with traditional elements; others have replaced it with graded sexual assault or criminal sexual conduct offenses. The minimum conduct required, the role of consent, the treatment of intoxication, and the availability of mistake-of-age defenses all differ by jurisdiction. Federal rape law applies primarily to offenses in federal jurisdiction (military, federal territories, certain Indian country offenses) and follows its own statutory framework.
