To deal with the grievances of the Hungarian noblemen, Louis held a Diet in late 1351. He confirmed all but one of the provisions of the Golden Bull of 1222, declaring that all noblemen enjoyed the same liberties in his realms. He rejected only the provision that authorized noblemen who died without a son to freely bequeath their estates. Instead, he introduced an entail system, prescribing that the estates of a nobleman who had no male descendants passed to his kinsmen, or if there were no male relatives to the Crown, upon his death. At the same Diet, Louis ordered that all landowners were to collect the "ninth", that is one tenth of specified agricultural products, from the peasants who held plots on their estates. On the other hand, he confirmed the right of all peasants to freely move to another landowner's estates.
