Why was the office of justice of the peace established in 1361?

The office of justice of the peace was established by statute in 1361 during the reign of Edward III to address ongoing challenges in maintaining law and order.

Throughout the 14th century, England faced significant instability, including gang warfare and a major crime wave in 1346–47, which was exacerbated by soldiers returning from France. Previous attempts to manage these issues—such as extending the jurisdiction of the king’s bench or utilizing broad accusations of treason—were met with resistance from the Commons, who argued these methods were ineffective and impoverished the populace.1

The creation of the justice of the peace marked a success for the Commons, who had long favored locally appointed officials over the centralization of judicial authority. By formalizing this office, the 1361 act began the process of centralizing the administration of justice while transitioning away from the older system of community-based, obligatory policing. These officials were granted police, judicial, and administrative duties, deriving their authority directly from the monarch.12
