The Bishop of Durham remained nominally in subjection to the see of York, but in reality he was often a greater man than his superior. In 1134 the Bishopric of Carlisle was founded and placed under the authority of the archbishops. Sodor and Man afterwards fell again under his jurisdiction, and in 1542 the diocese of Chester was founded. The archbishop has now authority over nine bishoprics. But to return to Thomas. In 1071 he went with Lanfranc to Rome to receive the pall. The question of precedence was there argued, and the Pope decided in favour of Canterbury. Afterwards, at a synod held by William, it was decided that the Archbishop of York should swear allegiance to Canterbury, and must be consecrated in Canterbury Cathedral, that the diocese of York from that time should not extend south of the Humber, and that the archbishop should lose his authority over the see of Worcester. On the death of Lanfranc, however, the dispute broke out again. For four years there was a vacancy to the see of Canterbury; Anselm, the new archbishop, was consecrated by Thomas, who took the opportunity to insist that Anselm should not be styled Primate of all England. The quarrel with Canterbury remained in abeyance until Thurstan was appointed Archbishop of York (1114 A.D.). He refused to make submission to Canterbury, and the Archbishop of Canterbury was determined not to consecrate him until he submitted. There was, therefore, a deadlock. Thurstan had the support of the Pope, but he was not consecrated until 1119, when the Pope Calixtus himself performed the ceremony at Rheims. Thurstan obtained a Bull from the Pope releasing him and his successors for ever from supremacy of Canterbury, and for a time York was triumphant.
In the reign of Henry II. the quarrel again broke out. This time the Archbishop of York, Roger Pont L'Eveque, the builder of the Norman choir of the minster, had the support of the king, who was engaged in the struggle with Becket. Roger, indeed, has been bitterly reviled as an accessory to the murder of Becket. He carried on the quarrel with Richard of Canterbury, Becket's successor, and at the Council of Westminster (1176 A.D.) the rivalries of the two prelates came to a head in a ridiculous scene. The papal legate was present at the council, and the Archbishop of Canterbury seated himself at his right hand. Shortly afterwards entered the Archbishop of York, who, refusing to take a lower place, sat down in the lap of Canterbury. He was seized, beaten, and kicked for his pains.
