How did keeping some Saxon customs help William conquer England?

Keeping some Saxon customs helped William conquer England by allowing him to gain the support of the local populace and maintain stability. By integrating certain Saxon traditions and laws into his rule, William eased the transition from Saxon to Norman governance, reducing resistance. This approach also helped him legitimize his authority and foster loyalty among the Anglo-Saxon nobility, which was crucial for consolidating his power in the newly conquered territory. Ultimately, this strategy facilitated a smoother integration of Norman rule while minimizing unrest.
