Despite the submission of the English nobles, resistance continued for several years. There were rebellions in Exeter in late 1067, an invasion by Harold's sons in mid-1068, and an uprising in Northumbria in 1068. In 1069 William faced more troubles from Northumbrian rebels, an invading Danish fleet, and rebellions in the south and west of England. He ruthlessly put down the various risings, culminating in the Harrying of the North in late 1069 and early 1070 that devastated parts of northern England. A further rebellion in 1070 by Hereward the Wake was also defeated by the king, at Ely.

Key Findings:

• Over the following 88 years, four Norman rulers dominated and ruled the kingdom, profoundly altering England's social, political, and physical landscape.;
• The Norman conquest was especially damaging to the Anglo-Saxon elite.
• As a result of the Norman Conquest, castles are brought in. Prior to 1066, England had around six castles; by the time William died, it had several hundred.
• The Normans also had diverse notions about architecture. They demolished most of the Anglo-Saxon abbeys and cathedrals and replaced them with massive new Romanesque structures. They even had opposing views on human existence.
• Within a generation or two following the conquest, the 15 to 20% of English society who had been kept as slaves were freed.
