The common lawso named because it was "common" to all the king's courts across Englandoriginated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066. Prior to the Norman Conquest, much of England's legal business took place in the local folk courts of its various shires and hundreds. A variety of other individual courts also existed across the land: urban boroughs and merchant fairs held their own courts, as did the universities of Oxford and Cambridge, and large landholders also held their own manorial and seigniorial courts as needed. The degree to which common law drew from earlier Anglo-Saxon traditions such as the jury, ordeals, the penalty of outlawry, and writs all of which were incorporated into the Norman common law is still a subject of much discussion. Additionally, the Catholic Church operated its own court system that adjudicated issues of canon law.
