1. Control and security: Castles served as strategic strongholds for the Normans, allowing them to control key locations and maintain their dominance over the conquered Anglo-Saxon population. They provided a secure base from which the Normans could launch military campaigns and suppress any potential rebellions. Castles acted as centers of local administration, aiding in maintaining law and order in the newly established feudal system.
2. Administrative hubs: Castles functioned as administrative centers for the Norman lords and their administration. They housed important governmental officials, courts, and record-keeping facilities. The castles became focal points for the management of estates and the collection of taxes and other dues from the surrounding territories.
3. Economic assets: Castles played a significant economic role by fostering trade and commerce. They attracted merchants and artisans who settled around the castle walls, forming bustling market towns. The economic activities generated by these communities benefited both the castle's inhabitants and the surrounding region, contributing to the overall economic development of the area.
