Lanfranc: The Archbishop Who Normanised the English Church
Written by Simon Williams
Lanfranc, an Italian lawyer turned Benedictine monk, became Archbishop of Canterbury in 1070 and spent nineteen years rebuilding the English Church around Norman authority. He replaced almost every English bishop, created separate church courts, and secured Canterbury's supremacy over York, reshaping English religious life for centuries.
- Name: Lanfranc, Archbishop of Canterbury
- Born: c.1005 to 1010, Pavia, Lombardy
- Died: 24 May 1089, Canterbury
- Appointed: Consecrated Archbishop of Canterbury on 29 August 1070
- Key achievement: Confirmed Canterbury's primacy over York at the Council of Winchester, 1072
- Prior role: Prior of Bec Abbey, then first Abbot of St Stephen's, Caen
When William the Conqueror needed someone to remake the English Church in his image, he did not choose a soldier or a politician. He chose a lawyer from Pavia who had spent decades as a monk in Normandy, a man in his sixties who reportedly had to be persuaded into the job. That choice tells you almost everything about how deliberate William's approach to conquest actually was.
Lanfranc's appointment as Archbishop of Canterbury in 1070 was not a reward or an afterthought. It was the second half of the Conquest, the half that happened in cathedrals and church councils rather than on battlefields. Where William's castles physically controlled the English landscape, Lanfranc's reforms controlled its spiritual and institutional life, and the two projects ran in close parallel.
This article traces how a reluctant Italian scholar became the architect of the Normanised English Church, and why his reforms outlasted the Conquest itself by centuries.
From Pavia to Bec: Lanfranc's Path to Power

Lanfranc was born in Pavia, in Lombardy, around 1005, the son of a man who held a position roughly equivalent to a magistrate. He trained in the liberal arts in a region of Italy renowned for legal scholarship, and he practised and taught law before crossing into Normandy. Around 1039 he opened a school at Avranches, where he built a considerable reputation as a teacher.
What I find genuinely striking about Lanfranc's career is the abruptness of his turn toward monastic life. Sometime around 1042, he abandoned his teaching position and entered the small, impoverished monastery of Bec, then little more than a struggling community under its founder, Abbot Herluin. Lanfranc rose to become prior, and under his direction the school at Bec became one of the most celebrated centres of learning in Europe, drawing pupils from France, Germany, Flanders and Italy. One of those pupils, Anselm of Aosta, would eventually succeed Lanfranc as Archbishop of Canterbury.
Lanfranc's relationship with William, Duke of Normandy, began during this period and was not initially friendly. He opposed William's marriage to Matilda of Flanders in 1053 on grounds of consanguinity, but the two men reconciled and Lanfranc became one of the duke's most trusted ecclesiastical advisers. William made him the first abbot of his new foundation of St Stephen's at Caen around 1063, a position that placed Lanfranc at the centre of Norman religious and political life in the years immediately before the invasion of England.
Appointment to Canterbury

The Archbishopric of Canterbury that Lanfranc inherited in 1070 was in a state of considerable disorder. Stigand, the incumbent archbishop, had held his position through years of controversy, accused of simultaneously holding the sees of Canterbury and Winchester and never having received his pallium in a manner Rome considered fully canonical. In 1070, a papal delegation visiting England confirmed these charges, and Stigand was formally deposed and imprisoned at Winchester, where he died two years later.
William chose Lanfranc as his replacement, and by most accounts Lanfranc was genuinely reluctant to accept. He was in his sixties, already established as abbot at Caen, and it took considerable persuasion, reportedly involving direct papal instruction, before he agreed to take the post. He was consecrated Archbishop of Canterbury on 29 August 1070, in a ceremony attended by several bishops including Walkelin of Winchester and Walter of Hereford.
Once installed, Lanfranc moved quickly. He took up residence in a city and a church badly damaged during the years of conquest and rebuilt Canterbury Cathedral from the ground up, modelling the new structure on his own abbey church at Caen. The rebuilt cathedral, using imported Caen stone, stood as a physical statement of Norman authority as much as a religious one. For a fuller picture of how stone became a tool of Norman control across England more broadly, see our article on Norman Castles: How William I Used Stone to Control England, which covers the same logic applied to fortification rather than worship.
The Council of Winchester and the Primacy Dispute

Lanfranc's first serious institutional battle was not with the English but with a fellow Norman appointee. Thomas of Bayeux, installed as Archbishop of York in 1070, argued that his see was entirely independent of Canterbury and claimed jurisdiction over a substantial portion of the English Midlands. This dispute, which became known as the Canterbury to York primacy dispute, threatened to undermine the unified Church structure William needed to govern effectively.
Lanfranc travelled to Rome to receive his pallium and used the visit to secure an order from Pope Alexander II that the dispute be resolved by a council of the English Church. That council met at Winchester in 1072. Here Lanfranc obtained formal confirmation of Canterbury's primacy over York, establishing a hierarchy that would structure English ecclesiastical governance for the rest of the medieval period. He was never able to secure the papacy's own formal ratification of this primacy, in part due to the accession of the far more assertive Pope Gregory VII in 1073, but the practical authority the Council of Winchester granted him within England went largely unchallenged for the remainder of his tenure.
The Council of Winchester also formed part of a broader pattern of church councils through which Lanfranc reorganised English ecclesiastical structure, including a later council that relocated several English bishoprics from rural Anglo-Saxon sites to more prominent towns, moving the sees of Sherborne and Wilton to Old Sarum and Selsey to Chichester.
Normanising the English Church
The most consequential and, from an English perspective, most disruptive aspect of Lanfranc's tenure was his systematic replacement of the English episcopate with Norman appointees. Within a few years of his own appointment, Wulfstan of Worcester remained the only English born bishop still holding office in the entire country. This is the detail that changes everything about how we should read Lanfranc's reforms: they were not simply spiritual renewal, they were an instrument of conquest, extending Norman control into every diocese in England.
Notably, Lanfranc maintained a genuine and lasting friendship with Wulfstan, the one English bishop he did not remove, which suggests his policy of replacement was driven by political necessity and trust in his own Norman network rather than blanket hostility to English clergy as individuals.
Lanfranc's reforms extended well beyond personnel. In an ordinance issued around 1076, he formally separated secular courts from ecclesiastical courts, establishing church courts with jurisdiction over clerical matters independent of the king's own justice system. This was a genuinely significant legal innovation, one that historians consider an important early step in the development of a distinct canon law tradition in England, separate from but coexisting with the developing common law. Readers interested in how this ecclesiastical legal authority intersected with royal justice more broadly may find our article on The Role of the Church in Medieval Justice useful for tracing this thread forward into the thirteenth century.
Lanfranc as Statesman and Royal Adviser

Lanfranc's influence was never confined to purely ecclesiastical matters. William trusted him to govern England as a viceroy during the king's frequent absences in Normandy, a role that made Lanfranc, in practical terms, one of the most powerful men in the kingdom whenever William was overseas. He is credited with detecting the conspiracy formed against William in 1075 by the Earls of Norfolk and Hereford, intelligence that allowed the rebellion to be crushed before it could gather serious momentum.
His political judgement proved decisive again at the very end of William's reign. On the Conqueror's death in 1087, Lanfranc used his considerable influence to secure the English succession for William Rufus over his elder brother Robert Curthose, persuading the English militia to back Rufus's claim. Lanfranc personally crowned Rufus at Westminster Abbey less than three weeks after the Conqueror's death, a coronation that effectively settled a succession question that could otherwise have plunged England back into civil conflict.
What strikes me most about Lanfranc's career is how completely his personal authority substituted for formal institutional power. He held no crown and commanded no army, yet his judgement shaped English royal succession twice within a single generation. That is not a small legacy for a reluctant archbishop who had to be talked into the job.

When was Lanfranc appointed Archbishop of Canterbury?
Lanfranc was consecrated Archbishop of Canterbury on 29 August 1070, following the formal deposition of his predecessor Stigand earlier that year on charges relating to the canonical irregularity of his appointment. William the Conqueror had personally selected Lanfranc, who was by most accounts initially reluctant to accept the position given his existing role as Abbot of St Stephen's, Caen.
What was the Council of Winchester and why did it matter?
The Council of Winchester met in 1072 to resolve a jurisdictional dispute between Lanfranc and Thomas of Bayeux, the newly appointed Archbishop of York, over whether York's see was independent of Canterbury. The council confirmed Canterbury's primacy over York, establishing a hierarchy within the English Church that Lanfranc used to unify ecclesiastical governance under his own authority for the rest of his tenure.
Why did Lanfranc replace English bishops with Normans?
Lanfranc's replacement of the English episcopate with Norman appointees was part of William the Conqueror's broader strategy to secure control over England following the Conquest. Within a few years, Wulfstan of Worcester was the only remaining English born bishop in the country. This policy extended Norman authority into every diocese, mirroring the secular replacement of the English landholding aristocracy happening at the same time.
What did Lanfranc's 1076 ordinance actually do?
Lanfranc's ordinance of around 1076 formally separated ecclesiastical courts from secular royal courts in England, giving church courts independent jurisdiction over clerical and religious matters. This was a significant legal development, laying groundwork for a distinct canon law tradition in England that operated alongside, rather than within, the developing royal common law system.
How influential was Lanfranc beyond church affairs?
Lanfranc served as William the Conqueror's trusted viceroy during the king's frequent absences in Normandy, governing England in his stead. He is credited with detecting the 1075 conspiracy of the Earls of Norfolk and Hereford before it could threaten William's rule, and after the Conqueror's death in 1087 he used his authority to secure the English throne for William Rufus, whom he personally crowned at Westminster Abbey.
Did Lanfranc get along with any English clergy?
Yes. Despite his broader policy of replacing English bishops with Normans, Lanfranc maintained a close and lasting friendship with Wulfstan of Worcester, the one English bishop who kept his position throughout Lanfranc's tenure. This relationship suggests Lanfranc's replacement policy was rooted in political necessity rather than a blanket hostility toward English churchmen as individuals.
