Definition
To incite is to urge, provoke, or stimulate another person to commit a criminal act. Incitement is the offense that arises from that conduct — the act of encouraging, instigating, or stirring up another to do something unlawful.
As a crime, incitement does not require that the underlying offense actually occur. The gravamen of the offense is the inciter's conduct in attempting to move another toward crime, not the ultimate result. A person who urges another to commit murder is guilty of incitement whether or not the murder takes place.
Incitement operates at the boundary between thought, speech, and criminal liability. It differs from conspiracy in that incitement is typically unilateral — one person urging another — whereas conspiracy requires mutual agreement. It differs from solicitation in some formulations, though the two terms are often treated as synonyms in modern criminal codes.
In constitutional law, incitement takes on a separate and highly significant meaning in First Amendment doctrine. Under the standard established in Brandenburg v. Ohio, 395 U.S. 444 (1969), speech may not be punished as incitement unless it is directed to producing imminent lawless action and is likely to produce such action. This constitutional threshold is distinct from the common law criminal definition and constrains how incitement statutes may be written and applied.

Common Language
Modern common usage (Wiktionary): To incite means to encourage or stir up violent or unlawful behavior; to rouse someone to action, often to something harmful or passionate.
Historical common usage (Webster's 1913): "To move to action; to stir up; to rouse; to spur or urge on." Webster's gives the word a broad emotional valence — inciting courage, inciting rebellion, inciting a crowd — without reference to legal consequence.
The gap between ordinary and legal meaning is narrower here than with many legal terms, but it matters. In common usage, inciting a crowd to cheer, to vote, or to protest is entirely neutral or positive. In legal usage, incitement attaches specifically to criminal conduct as its object, and in constitutional doctrine, a further layer of precision applies: not all speech urging unlawful action qualifies as legally punishable incitement. The ordinary speaker using "incite" loosely should not assume the legal definition tracks everyday usage.

Common Confusion
Incitement and solicitation are frequently conflated, and many jurisdictions use them interchangeably. Where a distinction is maintained, solicitation typically refers to urging another to commit a specific offense for the solicitor's benefit or at the solicitor's direction, while incitement is broader — stirring up action in others without necessarily directing it toward oneself. In practice, modern criminal codes (including the Model Penal Code) have largely absorbed both under solicitation, making the distinction more historical than operational in many U.S. jurisdictions.
Incitement and conspiracy are sometimes confused in public discourse. The critical difference: conspiracy requires a bilateral agreement (two or more parties agreeing to commit an offense), while incitement can be entirely one-sided. A person who delivers a speech urging others to riot is not automatically a conspirator merely because some listeners comply.
In First Amendment contexts, the legal term "incitement" carries a specific doctrinal meaning under Brandenburg that differs sharply from the criminal law definition. Conflating these two registers — treating criminal incitement and constitutional incitement doctrine as the same analysis — is a common research error.

Why It Matters in Research
The single most important navigational point for corpus researchers: incitement means different things in criminal law and in constitutional law, and historical sources often fail to mark the distinction cleanly. Pre-twentieth-century materials and older dictionary entries like Rapalje & Lawrence address incitement purely as a criminal law concept. The First Amendment dimension of incitement doctrine is largely a twentieth-century development, crystallizing through a line of cases running from Schenck v. United States (1919) through Brandenburg v. Ohio (1969). Researchers working in historical sources will not find the constitutional layer addressed.
For criminal law research, the Rapalje & Lawrence formulation — incitement is a misdemeanor whether or not the crime is committed — reflects the traditional common law baseline. However, the severity of incitement offenses has shifted considerably. Under modern statutes, incitement to a serious felony may itself be charged as a serious offense rather than a generic misdemeanor. Do not use the historical misdemeanor classification as a reliable guide to contemporary sentencing exposure.
The Rapalje & Lawrence entry appends the maxim Incivile est, nisi tota sententia inspecta, de aliqua parte judicare — "it is improper to judge of any part unless the whole sentence be examined." This is an interpretive canon from Hobart, not a rule specific to incitement. Its placement in the incitement entry is a formatting artifact of the original dictionary, not a signal that the maxim has special application to incitement doctrine. Researchers should not read substantive significance into the pairing.
Jurisdictional variation in how incitement, solicitation, and attempt interact with the underlying offense is significant. Some jurisdictions merge these into consolidated inchoate offense frameworks; others preserve distinct charges. When tracing how an incitement charge was brought in a historical case, verify the applicable statute and whether the jurisdiction used "incitement" as a term of art or as a synonym for solicitation.
Researchers working on riot, unlawful assembly, or mob action cases will find incitement doctrine closely intertwined with those offenses. The Encyclopedia entry on Riot, Unlawful Assembly, and Incitement is the natural companion resource.

Historical Dictionary Support
Rapalje & Lawrence's entry is brief and functional: incitement is a misdemeanor committed by urging another to crime, and the offense is complete regardless of whether the crime follows. This captures the core common law principle accurately. The source does not address incitement in the context of sedition, public speech, or political agitation — areas where nineteenth-century law was actively contested and where the modern constitutional framework would eventually develop.
The citation to Stephen's Criminal Digest (Steph. Cr. Dig. 29) is characteristic of the period: Stephen's work was a leading synthesis of English criminal law and would have been well understood by practitioners on both sides of the Atlantic in the late nineteenth century. Researchers tracing the English common law pedigree of incitement doctrine will find Stephen useful, though his formulations predate the American constitutional developments that reshaped incitement analysis in the twentieth century.
Historical dictionaries generally treat incitement as a minor, ancillary offense — the misdemeanor catch-all for those who urge but do not act. This framing understates the significance incitement would acquire in political and civil rights contexts. The gap between the historical dictionary treatment and the modern legal significance of incitement doctrine is substantial.

Jurisdictional Note
In the United States, incitement as a free-standing criminal charge has been substantially absorbed into solicitation and attempt frameworks under modern penal codes, though the term remains in use in statutes addressing riot, sedition, and hate crimes. The First Amendment's Brandenburg standard applies in all U.S. jurisdictions as a constitutional floor, limiting how broadly incitement may be defined by statute. English and Commonwealth jurisdictions retain "incitement" as a recognized common law and statutory category with a distinct lineage.
