How did William I limit the pope’s authority in England?

William I maintained firm control over the English church and actively resisted the claims of papal supremacy asserted by Pope Gregory VII. To limit the pope’s authority within his realm, William established several royal decrees that effectively curtailed direct ecclesiastical interference from Rome:1

• Recognition of the Pope: No pope could be recognized in England without the king’s prior consent.1
• Papal Correspondence: No letters or communications from the pope could be received in England without royal approval.1
• Legislative Control: No church council was permitted to legislate without the king’s authorization.1
• Excommunication: No baron or royal official could be excommunicated by the church without the king’s permission.1

Additionally, William denied that he owed homage or fealty to the pope for his English lands. By keeping the upper ranks of the clergy under strict royal control—where bishops received their lands and symbols of office directly from him—William ensured that the English church remained subordinate to the crown rather than the papacy.1
