Norman consolidation of power
1. Many rebellions in England against Norman rule between 1067 and 1075
2. Most of the rebellions were easy to put down as they lacked co-ordination or strong leadership
3. William's treatment of rebels became harsher over time: at first he accepted some rebels' surrender without harsh repercussions, but later he devastated parts of the country and killed rebels (such as in the Harrying of the North, 1069)
