When the see of Rouen next fell vacant (1067), the thoughts of the electors turned to Lanfranc.
But he declined the honour, and he was nominated to the English Primacy as Archbishop of Canterbury as soon as Stigand had been canonically deposed on 15 August 1070.
He was speedily consecrated on 29 August 1070.
The new archbishop at once began a policy of reorganisation and reform.
His first difficulties were with Thomas of Bayeux, Archbishop-elect of York, (another former pupil) who asserted that his see was independent of  Canterbury and claimed jurisdiction over the greater part of the English Midlands.
This was the beginning of a long running dispute between the sees of Canterbury and York, usually known as the Canterbury–York dispute.

Lanfranc, during a visit which he paid the pope for the purpose of receiving his pallium, obtained an order from Alexander that the disputed points should be settled by a council of the English Church.
This was held at Winchester in 1072.
At this council Lanfranc obtained the confirmation of his primacy that he sought; nonetheless he was never able to secure its formal confirmation by the papacy, possibly as a result of the succession of Pope Gregory VII to the papal throne in 1073.

Lanfranc assisted William in maintaining the independence of the English Church; and appears at one time to have favoured the idea of maintaining a neutral attitude on the subject of the quarrels between papacy and empire.
In the domestic affairs of England the archbishop showed more spiritual zeal.
His grand aim was to extricate the Church from the fetters of corruption.
He was a generous patron of monasticism.
He endeavoured to enforce celibacy upon the secular clergy.

Lanfranc obtained the king's permission to deal with the affairs of the Church in synods.
In the cases of Odo of Bayeux (1082) (see Trial of Penenden Heath) and of William of St Calais, Bishop of Durham (1088), he used his legal ingenuity to justify the trial of bishops before a lay tribunal.

Lanfranc accelerated the process of substituting Normans for Englishmen in all preferments of importance; and although his nominees were usually respectable, it cannot be said that all of them were better than the men whom they superseded.
For this admixture of secular with spiritual aims there was considerable excuse.
By long tradition the primate was entitled to a leading position in the king’s councils; and the interests of the Church demanded that Lanfranc should use his power in a manner not displeasing to the king.
On several occasions when William I was absent from England Lanfranc acted as his vicegerent.

Lanfranc's greatest political service to the Conqueror was rendered in 1075, when he detected and foiled the conspiracy which had been formed by the earls of Norfolk and Hereford.
Waltheof, 1st Earl of Northumberland, one of the rebels, soon lost heart and confessed the conspiracy to Lanfranc, who urged Earl Roger, the earl of Hereford to return to his allegiance, and finally excommunicated him and his adherents.
He interceded for Waltheof’s life and to the last spoke of the earl as an innocent sufferer for the crimes of others; he lived on terms of friendship with Bishop Wulfstan of Worcester.

On the death of the Conqueror in 1087 Lanfranc secured the succession for William Rufus, in spite of the discontent of the Anglo-Norman baronage; and in 1088 his exhortations induced the English militia to fight on the side of the new sovereign against Odo of Bayeux and the other partisans of Duke Robert.
He exacted promises of just government from Rufus, and was not afraid to remonstrate when the promises were disregarded.
So long as he lived he was a check upon the worst propensities of the king’s administration.
But his restraining hand was too soon removed.
In 1089 he was stricken with fever and he died on 24 May amidst universal lamentations.
Notwithstanding some obvious moral and intellectual defects, he was the most eminent and the most disinterested of those who had co-operated with William I in riveting Norman rule upon the English Church and peop
