WHAT YOU'LL LEARN
The Norman Church
The Norman Conquest transformed the English Church as completely as it transformed the English aristocracy. Within twenty years, almost every bishop and abbot in England had been replaced by a Norman or Continental churchman. Archbishop Lanfranc systematically reformed the Church's organisation, discipline and buildings. New cathedrals rose across the country. But the Normans also introduced new tensions — between the Church and the Crown, and between England and the Papacy — that would define English religious politics for the next four centuries.
The Anglo-Saxon Church before 1066
Before we can understand what the Normans changed, we need to know what they found. The Anglo-Saxon Church was not corrupt or incompetent — it had produced serious scholars, active missionaries, and fine manuscript art. But from a Continental perspective, it had some problems.
The Anglo-Saxon Church was closely tied to local and royal power. Bishops were often appointed by the king or by powerful nobles, and some combined ecclesiastical and secular roles in ways that Continental reformers found improper. Some clergy were married — technically forbidden, but widely tolerated. The papacy in Rome had relatively little direct influence over English church affairs. From the perspective of the reform movement that was sweeping the Continent in the mid-eleventh century, the English Church needed modernising.
William used this as part of his justification for conquest. The Pope had supported his invasion partly because he promised to reform the English Church and bring it into closer alignment with Rome. When William arrived, he kept that promise — and Lanfranc was his instrument.
Archbishop Lanfranc and the reform of the English Church
Lanfranc (c1005–1089) was an Italian-born scholar who had become Prior of the monastery at Bec in Normandy, then Abbot of William's great foundation at Caen. He was one of the finest theologians in Europe and a brilliant administrator. William appointed him Archbishop of Canterbury in 1070 — the most senior position in the English Church.
Lanfranc's reforms were systematic and far-reaching:
Replacing the leadership: Almost all the existing Anglo-Saxon bishops and abbots were replaced with Normans or Continentals — men loyal to William and educated in Continental reform traditions. By the time of William's death in 1087, there were only two English-born bishops remaining in England.
Building programme: Lanfranc almost immediately demolished the Anglo-Saxon cathedral at Canterbury and began rebuilding it in the Norman Romanesque style. This pattern was repeated across England — at Durham, Winchester, Lincoln, York, Worcester and many other centres. These were not simply replacements: they were enormous, ambitious buildings designed to express the power and permanence of Norman Christianity.
Church organisation: Lanfranc held councils of the English Church, clarified the rules governing clergy, enforced clerical celibacy more strictly, and organised the Church's administrative hierarchy more clearly.
Separating Church courts: One of the most significant changes: Lanfranc (with William's support) separated the Church's legal jurisdiction from the secular courts. Before 1066, ecclesiastical and secular cases had often been heard in the same court. After the reform, the Church had its own courts dealing with matters of sin, marriage, wills, and clerical offences. This created a dual legal system that would generate conflict between Church and Crown for centuries.
Key individual
Archbishop Lanfranc (c1005–1089)
Born in Pavia in northern Italy, Lanfranc was one of the foremost scholars of the eleventh century — his teaching at Bec attracted students from across Europe. He became close to William and served as his chief advisor in Normandy before the Conquest. As Archbishop of Canterbury from 1070 until his death in 1089, he transformed the English Church: new leadership, new buildings, new administrative structures. He was also a pragmatist: he maintained good relations with William while supporting Church reform, navigating the tension between royal and papal authority with considerable skill. His death in 1089 left William II without that steadying influence — with consequences that became clear in the conflicts that followed.
The wealth of the Church
The Normans dramatically increased the economic power of the Church. The Domesday Book records that the Church held approximately one quarter to one third of all land in England — making it by far the largest collective landowner after the Crown.
This wealth came from several sources: royal gifts, grants from pious nobles seeking prayers for their souls, and the acquisition of land through bequests. The Normans were generous donors to the Church, particularly to monasteries — partly out of genuine piety, partly because monks prayed for the souls of the living and the dead, and partly because founding a monastery was a prestigious act that demonstrated a family's power and godliness.
The Church's wealth also meant the Church was deeply embedded in the feudal system. Bishops and abbots held land from the king as tenants-in-chief, and therefore owed the same feudal obligations — including, controversially, military service. The tension between a bishop's spiritual role and his feudal military obligations was one of the defining problems of the medieval Church.
William II and the Church: a stormier relationship
William II (William Rufus, reigned 1087–1100) had a far more difficult relationship with the Church than his father. He was irreligious by temperament, and he found in the Church's wealth an irresistible source of income.
When a bishop died, the king had the right to manage the diocese — and collect its revenues — until a new bishop was appointed. William II exploited this extensively, keeping bishoprics and abbacies vacant for long periods to maximise his income. When Lanfranc died in 1089, William left the archbishopric of Canterbury vacant for four years.
When he finally appointed Anselm of Bec as Archbishop of Canterbury in 1093 (under pressure when he thought he was dying), the conflict intensified. Anselm was a principled reformer who refused to compromise on Church independence. The two clashed repeatedly — over papal authority, over who had the right to appoint bishops, and over Church courts.
Key controversy
The Investiture Controversy
At the heart of the Church-Crown conflict was a question: who has the right to appoint bishops — the Pope or the king? This was the Investiture Controversy, which was raging across Western Europe in the late eleventh century. "Investiture" referred to the ceremony by which a bishop was given the symbols of his office (a ring and a staff). The reforming papacy argued that only the Pope could invest bishops, because they were spiritual officers. Kings argued that because bishops held land from the Crown and owed feudal service, the king had to be involved. In England, the controversy came to a head under William II and continued into Henry I's reign, only resolved by the Concordat of London in 1107.

- Describe the Norman cathedral-building programme. Why was it significant beyond simply replacing old buildings?
- Why did Lanfranc separate Church courts from secular courts? What was the long-term significance of this change?
- How much land did the Church hold in Norman England? Why did this create tensions?
- How did William II's relationship with the Church differ from his father's?
- What was the Investiture Controversy? What was at stake?
- Overall, how much did the Norman Conquest change the English Church?

Title: Lanfranc's revolution — how the Normans reformed the English Church
When William conquered England, he replaced almost the entire Church leadership with Normans — starting with Archbishop Lanfranc at Canterbury. The result was one of the most sweeping reforms of the medieval Church: new buildings, new organisation, and a new relationship between the crown and Rome. This page explains what changed, what didn't, and why the Investiture Controversy mattered.
