The Parliament of England was the legislature of the Kingdom of England. In 1066, William of Normandy introduced what, in later centuries, became referred to as a feudal system, by which he sought the advice of a council of tenants-in-chief (a person who held land) and ecclesiastics before making laws. In 1215, the tenants-in-chief secured Magna Carta from King John, which established that the king may not levy or collect any taxes (except the feudal taxes to which they were hitherto accustomed), save with the consent of his royal council, which gradually developed into a parliament.
