Why did the rebellions not succeed against William the conqueror?

The rebellions against William the Conqueror, particularly those like the Revolt of the Earls and the Harrying of the North, did not succeed due to several factors. William's strong military organization and his use of feudal loyalty ensured that he maintained control over his territories. Additionally, the rebellions often lacked unified leadership and sufficient resources, making it difficult for them to mount a sustained challenge. Finally, William's ruthless tactics, including widespread destruction, discouraged further resistance and solidified his power.
