What impact would William of Normandy and king John have on England?

William of Normandy, who became known as William the Conqueror, dramatically transformed England after his victory at The Battle of Hastings in 1066. He introduced feudalism, centralized governance, and commissioned the Domesday Book, which recorded land ownership and resources. King John, ruling from 1199 to 1216, is often remembered for his heavy taxation and conflicts with the nobility, which led to the signing of the Magna Carta in 1215. This document laid the foundation for constitutional governance and the principle of the rule of law, shaping the future of English democracy.
