| 1069 | 1070 | Harrying of the North |  William I of England |  House of Wessex | Internal Conflict, William was Victorious An uprising which started 4 years after the Norman Conquest. Edgar Ætheling, the grandson of Edmund Ironside and the last notable heir to the House of Wessex, fought with the support of the King of Denmark Sweyn II, Anglo-Saxons, and Anglo-Scandinavians. It ended in defeat for the Anglo-Saxons & Anglo-Scandinavians. William the Conqueror paid Sweyn and his Danish fleet to go home, but the remaining rebels refused to meet him in battle, and he decided to starve them out by laying waste to the northern shires using scorched earth tactics. The Norman campaign to reconquer Northern England resulted in a genocide against the people living there. |
