Apart from these considerations the objects of the rioters were of an economic nature. There was a general effort to destroy the rolls of the manor courts. These rolls, kept either in manor houses, or in the castles of great lords, or in the monasteries, were the record of the burdens and payments and disabilities of the villagers. Previous payments of heriot, relief, merchet, and fines, acknowledgments of serfdom, the obtaining of their land on burdensome conditions, were all recorded on the rolls and could be produced to prove the custom of the manor to the disadvantage of the tenant. It is true that these same rolls showed who held each piece of ground and defined the succession to it, and that they were long afterward to be recognized in the national courts as giving to the customary holder the right of retaining and of inheriting the land, so that it might seem an injury to themselves to destroy the manor court records. But in that period when tenants were in such demand their hold on their land had been in no danger of being disturbed. If these records were destroyed, the villains might well expect that they could claim to be practically owners of the houses and little groups of acres which they and their ancestors had held from time immemorial; and this without the necessity for payments and reservations to which the rolls testified. Again, lawyers and all connected with the law were the objects of special hostility on the part of insurgents. This must have been largely from the same general cause as that just mentioned. It was lawyers who acted as stewards for the great lords, it was through lawyers that the legal claims of lords of manors were enforced in the king's courts. It was also the judges and lawyers who put in force the statutes of laborers, and who so generally acted as collectors of the poll tax. More satisfactory relations with their lords were demanded by insurgents who were freeholders, as well as by those who were villains. Protests are recorded against the tolls on sales and purchases, and against attendance at the manorial courts, and a maximum limit to the rent of land is asked for. Finally, the removal of the burdens of serfdom was evidently one of the general objects of the rebels, though much of the initiative of the revolt was taken by men from Kent, where serfdom did not exist. The servitude of the peasantry is the burden of the sermon of John Ball at Blackheath, its abolition was demanded in several places by the insurgents, and the charters of emancipation as given by the king professed to make them "free from all bondage."
