Why was William 1 not popular?

William I, also known as William the Conqueror, faced unpopularity due to his harsh rule and the imposition of Norman culture on the Anglo-Saxon population after the Norman Conquest of 1066. His heavy taxation, confiscation of lands, and the establishment of a feudal system alienated many of his subjects. Additionally, the violence and destruction associated with his conquest bred resentment among the Anglo-Saxons, leading to ongoing rebellions and a lack of loyalty to his rule.
