The barons insisted that the old feudal contract should be reinstated and that the king should abide by the laws that the rest of the population did. The feudal contract allowed the barons to run their own lands, renting it from the king but paying rent by supplying knights rather than money. This feudal system had been set up by William the Conqueror. |
