Definition
An arrayer was a medieval English officer commissioned by the Crown to muster, inspect, and organize the able-bodied inhabitants of a county for military service. The arrayer acted under a commission of array — a royal directive authorizing the selection and preparation of local men for the king's forces. The arrayer's duties included reviewing the fitness and equipment of prospective soldiers, ensuring they were properly armed and accoutered, and reporting on the military readiness of a given region. The office was not permanent; arrayers were appointed as needed, typically in anticipation of war or civil unrest.
Common Language
Modern common usage (Wiktionary): One who arrays; an officer who provided soldiers with armor and took care of it.
Historical common usage (Webster's 1913): One who arrays; in some early English statutes, applied to an officer who had care of the soldiers' armor and saw them duly accoutered.
The common definitions are not wrong, but they are narrower than the full legal picture. The legal role of the arrayer was primarily organizational and governmental — a Crown-appointed official exercising quasi-military authority over civilian populations — not merely a quartermaster or equipment keeper. The armor-care function was incidental to the core duty of mustering and arraying men for service.
Why It Matters in Research
ARRAYER is a term of purely historical significance, relevant only to research touching medieval and early modern English military administration, constitutional history, or the origins of conscription and militia law. Researchers are unlikely to encounter it outside primary sources, year books, or treatises addressing the feudal and early common law period.
The key connection for legal research is the commission of array, the instrument under which arrayers operated. The commissions of array were a source of significant constitutional controversy in seventeenth-century England, particularly in the period leading up to the English Civil War, when Parliament disputed the Crown's authority to raise forces by commission rather than statute. A researcher tracing the history of militia law, the Petition of Right, or the constitutional debates of the 1640s will find ARRAYER appearing in the background of those disputes.
The term appears rarely in legal dictionaries and is essentially absent from modern legal writing. Its presence in Bouvier and Burrill reflects those works' comprehensive treatment of historical English law rather than any continuing legal relevance. Researchers working in digitized primary source collections should note that variant spellings — including ARAYER (the Law French form referenced by Burrill) and ARRAIER — may appear in manuscript and early printed sources.
Historical Dictionary Support
Bouvier and Burrill agree on the essential function of the arrayer but approach the term from different angles. Bouvier provides the more complete practical description, situating the arrayer within the county-level structure of medieval military administration and explicitly linking the office to the commission of array. Burrill's entry is skeletal, directing the reader to the Law French form ARAYER, which reflects the linguistic origins of the term in the Anglo-Norman administrative vocabulary of medieval England.
Neither dictionary addresses the constitutional dimension of the commission of array in any depth — understandable given their focus on definition rather than history. Researchers seeking that context must look beyond the dictionary shelf to historical and constitutional sources. Webster's 1913 aligns closely with the legal dictionaries on the armor-care function but does not capture the broader mustering and organizing role that made the arrayer a legally significant officer rather than a mere servant of military logistics.
