The Rebellion in Durham and the Building of a Castle

Following the death of Earl Robert Lee and his soldiers in Durham, the posture of the English changed from isolated local revolts to a full-scale rebellion. The Northumbrian army built a castle in Durham and strategically positioned it as a natural fortress, learning from the effectiveness of Norman castles. The rebellion in Durham was not a spontaneous act but part of a broader plan that involved gathering recruits and weakening the enemy for the larger campaign. The rebellion extended beyond Durham, as noble exiles and Scottish allies joined forces to retake England.
