Law in England during all this period was chiefly a system of oppression, proceeding stage by stage from the highest to the lowest. The revenues of the crown were obtained by extravagant rents, forfeits, taxes, reliefs, fines, aids, and other devices which show the amazing ingenuity of the extortioners. The result was that most tyrannical exactions were made in turn by the feudal lords, and the dependents groaned for six centuries under these lawless yet legalised oppressions. Personal property was at the mercy of the lords, who adopted the most cruel means to enforce their "rights." They, in turn, could be the victim of extortions, as was proved in the case of Roger of Dudley, who was summoned to receive the honour of knighthood in 1233. He found the honour so expensive that he declined to appear, whereupon a writ was issued--"Because Roger de Someri, at the feast of Pentecost last past, has not appeared before the King to be girded with the military girdle, the Sheriff of Worcestershire is hereby commanded to seize on the house of Dudley and all other lands of the said Roger within his jurisdiction, for the King's use; and to keep them with all the cattle found upon them, so that nothing may be moved off without the King's permission." The same Roger had a twelve years' dispute with William de Birmingham touching the service due for the manor of Birmingham, for which the latter was required to perform the service of eight knights' fees, a half and a fourth part, and also to do suit to the court at Dudley once every three weeks. In such wise did these cheftains rule. Another curious piece of law relating to the Dudley lands is told by Leland:--"The lorde Powis, grauntfather that is now, being in a controversy for asawte made upon hym goying to London by the lord Dudeley, Dudeley castelle condesended by entreaty, that his son and heir should mary the olde lorde of Dudleis' daughter." A very amiable method of atoning for personal violence.
