Royal judges spread a single legal system throughout medieval England primarily by establishing a centralized judiciary that extended the reach of the Kingās Court (Curia Regis) beyond Westminster.12
Key methods included:
- Circuit Courts: Royal judges traveled "on circuit" to provincial towns, bringing the law of Westminster to both civil and criminal cases across the country.13
- Control of Local Customs: While local customs existed, royal courts asserted authority over them, often rejecting those deemed unreasonable or unproved. The common law was presumed to apply everywhere unless a specific local custom could be proven.1
- The Writ System: The central court machinery utilized writsāwritten orders issued from the chancery in the kingās nameāto compel defendants to appear in royal courts or to ensure justice was administered in inferior courts.1
- Uniformity: By the 13th century, central courts like the Exchequer, Common Pleas, and Kingās Bench applied the same common law, further solidifying a consistent legal standard throughout the realm.1
