Overview
A constable is a person holding a particular office, most commonly in criminal law enforcement. The office of constable can vary significantly in different jurisdictions. A constable is commonly the rank of an officer within the police. Other people may be granted powers of a constable without holding this title.
Etymology
Historically, the title comes from the Latin comes stabuli (attendant to the stables, literally count of the stable) and originated from the Roman Empire; originally, the constable was the officer responsible for keeping the horses of a lord or monarch.
The title was imported to the monarchies of medieval Europe, and in many countries developed into a high military rank and great officer of State (e.g. the Constable of France, in French Connétable de France, who was the commander-in-chief of all royal armed forces (second to the king) until prime minister Cardinal Richelieu abolished the charge in 1627).
