Angevin Empire
Normandy was the most administrated state of the Angevin Empire after England. Prévôts and vicomtes lost their authority to baillis, who held both judicial and executive powers. These officials were introduced during the 12th century in Normandy and cause an organisation of the duchy similar to the sheriffs in England. Ducal authority was the strongest on the frontier near the Capetian royal demesne.
