Sweyn II of Denmark
The people of the North rebelled against the Normans in September 1069 AD, enlisting Sweyn II of Denmark. They tried to take back York, but the Normans burnt it before they could. What followed was the Harrying of the North ordered by William. From York to Durham, crops, domestic animals, and farming tools were scorched. Many villages between the towns were burnt and local northerners were indiscriminately murdered. During the winter that followed, families starved to death and thousands of peasants died of cold and hunger. Orderic Vitalis estimated that "more than 100,000" people from the North died from hunger.
