Definition
In historical English law, a term of legal classification applied to persons claiming divine inspiration, used as a general designation for Quakers, Anabaptists, and other nonconformist sectaries and dissenting groups who departed from the doctrine and practice of the Church of England. The term carried formal statutory weight under the Conventicle Act (13 Car. II, c. 6, 1661) and related Restoration-era legislation designed to suppress unauthorized religious assemblies.
The term has no operative legal meaning in modern law.

Common Language
Modern common usage (Wiktionary): Plural of fanatic; persons filled with excessive and irrational enthusiasm, especially in religious or political matters.
Historical common usage (Webster's 1913): "A person affected by excessive enthusiasm, particularly in religious matters; one who indulges wild and extravagant notions of religion."
In ordinary usage, the word carries a descriptive, psychological, or pejorative charge — connoting irrationality or extremism in any domain. The legal meaning as it appears in the historical dictionaries is narrower and more specific: a statutory classification denoting nonconformist religious dissenters in Restoration England, defined not by the intensity of their belief but by their separation from the established Church. A Quaker or Anabaptist was a "fanatic" in the legal sense by group membership under the statute, regardless of individual temperament.

Common Confusion
Do not conflate the legal term as defined by Restoration statute with the broader contemporary or even contemporaneous common usage. Seventeenth-century writers used "fanatic" both as a general insult and as a quasi-technical designator for nonconformists. Legal sources drawing on the Conventicle Act use it in the latter, more specific sense. Researchers encountering the term in Restoration-era legal materials should treat it as a term of statutory art, not a character description.

Why It Matters in Research
This term is almost entirely of historical significance and will surface in research touching on English religious history, the legal status of nonconformity, and the development of religious liberty doctrine.
Researchers should be aware of several navigational points:
First, the statutory anchor. All three source dictionaries trace the definition to 13 Car. II, c. 6 — the Conventicle Act of 1661, the first of the cluster of post-Restoration statutes known collectively as the Clarendon Code. That Act criminalized unauthorized religious assembly and made this statutory classification operative. Researchers working on the legal suppression of dissent in the 1660s–1680s should locate the Act itself; the dictionary entries reproduce a gloss, not the statutory text.
Second, the term disappears from operative law. With the Toleration Act of 1689 (1 Will. & Mar., c. 18), Protestant nonconformists gained legal protection, and the statutory force of classifications like "fanatics" effectively collapsed. By the eighteenth century the word had migrated back to general usage. No modern legal system employs this classification.
Third, the term's appearance in American legal materials would be anomalous. The Conventicle Act was an English statute with no direct application in the colonies, and the First Amendment's religion clauses foreclosed any equivalent statutory classification in American law. If the term appears in early American legal writing, it is almost certainly being used in its common rhetorical sense or in reference to English precedent.
Fourth, the consistent attribution across all three dictionaries to Jacob's Law Dictionary signals a shared source lineage rather than independent verification. Giles Jacob's Law Dictionary (various editions, early 18th century) is the upstream source for this entry, and researchers should treat the three entries as substantially one source.

Historical Dictionary Support
The three source dictionaries — Black's (1st Ed.), Rapalje & Lawrence, and Black's (2nd Ed.) — are in near-complete textual agreement, all traceable to Jacob. The minor typographical variation in Black's 2nd Ed. ("13 Car. I" rather than "13 Car. II") appears to be a printing error; the Conventicle Act was passed in the reign of Charles II, not Charles I, and both other sources correctly cite Car. II.
None of the source entries provide substantive legal analysis beyond the definitional gloss. They do not discuss enforcement mechanisms, penalties, or the broader Clarendon Code context. Historical dictionaries are adequate to establish that the term had legal significance; researchers need primary sources to understand how it functioned in practice.

Jurisdictional Note
Exclusively English in origin and application. No American jurisdiction adopted this statutory classification. Researchers in Scottish, Irish, or colonial legal history should verify whether analogous but differently named classifications appear in those jurisdictions' nonconformity legislation.
