Was created in 1326 under the watch system of policing to assist the shire reeve in controlling the county?

The system you are referring to is the "hundred" system, which was established in England during the medieval period, around the 13th century. It organized communities into groups for local governance and law enforcement, assisting the shire reeve (sheriff) in maintaining order. The hundred court dealt with minor offenses and local disputes, effectively aiding in the administration of justice and community control.
