Definition
A person or official who travels from place to place in the course of a duty or trade, rather than operating from a fixed location. The term appears in two distinct legal contexts:
1. ITINERANT JUSTICES (judicial): Judges or justices who travel a circuit to hold court in different locations, rather than sitting at a permanent seat. The classic English example is the justices in eyre, who rode defined circuits to hear Crown pleas across the kingdom. In American legal usage, circuit judges performing their riding duties were sometimes described by the same term.
2. ITINERANT TRADERS/VENDORS (regulatory): Merchants, peddlers, hawkers, and salesmen who travel from place to place to sell goods, as opposed to those who operate from a fixed shop or stall. This is the sense overwhelmingly predominant in American statutory and municipal law, where itinerant vendors became a regulated class subject to licensing, bonding, and geographic restrictions.

Common Language
Modern common usage (Wiktionary): Traveling from place to place; also used as a noun for a member of the Travelling Community in British/Irish usage.
Historical common usage (Webster's 1913): Passing or traveling about a country; not settled; used of preachers, courts, and peddlers.
The common meaning and the legal meaning are closely aligned in their core sense of movement and lack of fixed location. The gap that matters for researchers is categorical: in ordinary English, "itinerant" is a general adjective describing anyone who moves around. In law, itinerant became a technical term of art attached to specific, regulated classes — itinerant justices on one side, itinerant vendors on the other — each with distinct legal consequences, duties, and liabilities depending on context. A reader encountering the word in a historical legal document must ask which category applies before the meaning becomes legally operational.

Common Confusion
Do not conflate itinerant justices with circuit judges in the modern American sense. The English justices itinerant — particularly the justices in eyre — held extraordinary commissions to hear pleas of the Crown and conduct general inquiries that went far beyond the modern circuit judge's role. The term "itinerant" in a pre-nineteenth-century English source almost certainly points to this older, more sweeping institution. In post-colonial American sources, the judicial sense fades; "itinerant" in American statutory law almost always refers to the vendor and trader class.
Also avoid confusing itinerant vendors with hawkers and peddlers, though the terms frequently overlap. Some statutes treat them as synonymous; others draw technical distinctions based on whether the vendor travels door-to-door, operates from a temporary stall, or sells from a vehicle. Check the specific statutory definition operative in the jurisdiction and period under study.

Why It Matters in Research
Researchers working in English legal history before approximately 1300 will encounter itinerant almost exclusively in its judicial sense, pointing to the eyre system. Bouvier's cross-reference to EYRE is the key navigational signal: the eyre was the institutional heart of itinerant justice in medieval England, and the two entries should be read together.
In American legal materials from the mid-nineteenth century onward, the judicial sense nearly disappears. Itinerant vendor licensing statutes proliferated at the state and municipal level, driven by concerns about fraud, local merchants' competitive interests, and public order. Researchers analyzing police power cases, commerce clause challenges, or municipal licensing disputes from this period should expect to find "itinerant" used as a quasi-technical statutory term with a locally-defined meaning that may not match another jurisdiction's usage.
The key trap in historical sources: an undifferentiated search for "itinerant" across a mixed corpus of English and American materials will collapse two unrelated legal institutions into one apparent concept. The judicial sense and the vendor-regulation sense share only the word. Their legal frameworks, historical periods, and research pathways are entirely separate.
For corpus researchers, note that Anderson's Dictionary of Law entry retrieved under this term appears to be a misalignment in the source data — the text provided discusses issues and pleadings, not itinerant persons. Treat any Anderson citation to this entry with caution until verified against the original source.

Historical Dictionary Support
The historical dictionaries agree on the core definition — traveling, not fixed — but weight the two senses differently. Black's (1st ed.) and Bouvier treat itinerant as primarily a judicial term, pointing to circuit-riding justices. Black's (2nd ed.) is the most practically useful of the shelf sources because it acknowledges that American statutory and municipal law had already shifted the term's operative center of gravity toward traders and vendors, and it supplies case citations and statutory references that anchor the term to real regulatory disputes.
Burrill goes back to the Latin root (itinerans) and cross-references iter, which is useful for researchers working in medieval Latin legal texts where the adjectival and nominal forms vary. Rapalje & Lawrence correctly identifies the English justices itinerant with what later became justices of assize — a point of institutional continuity worth noting for researchers tracing the lineage of the English circuit court system.
What the historical dictionaries collectively miss: none engages with the constitutional dimensions of itinerant vendor regulation that American courts actively litigated in the late nineteenth and early twentieth centuries, particularly dormant commerce clause and equal protection challenges. Researchers expecting doctrinal guidance on those questions will not find it here and should turn to encyclopedia and case law sources.

Jurisdictional Note
In English law, the itinerant justice belongs to a medieval and early modern institutional context; the eyre was effectively extinct by the fourteenth century. In American law, the regulatory sense governs. State and municipal definitions of "itinerant vendor" varied considerably — some statutes required residency thresholds, others turned on the nature of goods sold or the mode of sale. Always identify the operative statutory definition in the specific jurisdiction before applying any general definition.
