Compromise of Avranches, 1176

A Post-Martyrdom Re-evaluation of Henry II’s Ecclesiastical Policy and the Constitutions of Clarendon

The reign of Henry II represents a pivotal epoch in the development of English jurisprudence, characterized by a relentless drive toward centralizing royal authority and defining the boundaries between the spiritual and temporal spheres. At the heart of this transformative period lay the Constitutions of Clarendon, a set of sixteen articles promulgated in 1164 that sought to codify the "ancestral customs" of the realm and restrict the burgeoning autonomy of the Church.1 While the murder of Thomas Becket in 1170 is often viewed as a definitive defeat for the King’s agenda, a granular analysis of the Compromise of Avranches in 1172 and the subsequent Agreement of Westminster in 1176 reveals a far more nuanced outcome. The following report examines the extent to which Henry II achieved his original aims, identifying the specific legal mechanisms through which he preserved royal prerogative despite the symbolic concessions necessitated by the archbishop’s martyrdom.

The Constitutional Framework of 1164 and the Objective of Restoration

The Constitutions of Clarendon were not presented by Henry II as a revolutionary set of new laws but rather as a "recognition" of the rights and liberties held by his grandfather, Henry I.2 This appeal to antiquity was a strategic necessity; in the medieval legal mindset, legitimacy was rooted in custom and precedent.4 Henry II inherited a kingdom still reeling from the "Anarchy" of King Stephen’s reign, a period during which the Church had significantly expanded its jurisdictional reach due to the collapse of central royal authority.5 By 1164, the King’s objective was to restore the Landeskirche model—an English church that was integral to the universal Catholic body but remained under the personal care and administrative oversight of the monarch.6

The sixteen articles were designed to address specific areas of friction where canon law had begun to encroach upon royal jurisdiction. These included the trial of "criminous clerks," the process of appeals to the Papacy, the control of ecclesiastical vacancies, and the right of advowson—the power to appoint clergy to specific benefices.1 The King argued that the lack of royal oversight had led to widespread lawlessness, citing over one hundred unpunished murders committed by clerics in the decade preceding the Council of Clarendon.1

The Sixteen Articles of the Constitutions of Clarendon

Article	Subject Matter	Intended Royal Control
1	Advowsons and Presentation	Disputes over church appointments to be settled in the King's court.1
2	Tenure of Churches	Churches of the King’s fee cannot be granted in perpetuity without his consent.1
3	Criminous Clerks	Accused clerics must answer in royal courts; once convicted, they lose Church protection.1
4	Clerical Travel	High clergy cannot leave the kingdom without the King’s permission.1
5	Excommunication	Excommunicated persons need not provide permanent pledges to the Church.7
6	Lay Accusations	Procedures for accusing laymen in episcopal courts to ensure legal standards.7
7	Tenants-in-Chief	No royal official or tenant-in-chief to be excommunicated without King’s consent.7
8	Appeals to Rome	Appeals proceed from archdeacon to bishop to King; no further without consent.1
9	Assize Utrum	Inquest of twelve men to determine if land is lay fee or ecclesiastical tenure.1
10	Royal Demesne	Procedures for citing residents of royal cities or boroughs before Church courts.7
11	Feudal Duties	Archbishops and bishops to hold their lands as baronies and perform royal services.9
12	Vacant Sees	Revenues of vacant sees belong to the King; elections to be held in his chapel.5
13	Magnates	Bringing powerful men to justice for wrongs against the Church.9
14	Forfeited Goods	Chattels under forfeiture to the King cannot be held by the Church.9
15	Pleas of Debt	Jurisdiction over debts, regardless of bond status, lies with the King.9
16	Ordination of Rustics	Sons of villeins cannot be ordained without the lord’s consent.1

The Conflict of Jurisdiction and the Martyrdom of 1170

The resistance to the Constitutions was led by Thomas Becket, who, despite his previous role as Henry’s chancellor and close ally, underwent a radical transformation upon his elevation to the See of Canterbury.6 Becket’s opposition was grounded in the emerging principles of Gregorian Reform, which asserted the total independence of the clergy from secular judgment.11 The most contentious point of the dispute centered on Article 3 regarding criminous clerks. Becket argued that subjecting a cleric to both a Church trial (leading to degradation) and a secular trial (leading to corporal punishment) constituted "double punishment," violating the theological principle that God does not judge twice in the same matter.12

The ensuing six-year exile and the bitter diplomatic struggle involving Pope Alexander III culminated in Becket’s return to England in late 1170 and his subsequent murder in Canterbury Cathedral by four of Henry’s knights.14 This event shocked Christendom and placed the King in an untenable position, forcing him to choose between total excommunication and an interdict on his lands, or a formal reconciliation with the Papacy.6 The resulting Compromise of Avranches in 1172 was the first stage of this reconciliation, providing the platform for a renegotiated relationship between Church and State.16

The Compromise of Avranches 1172: Semantic Victory through Legal Ambiguity

The Compromise of Avranches, formalized in May 1172 at Avranches Cathedral, is frequently characterized as a total capitulation by Henry II. Under the supervision of papal legates Rotrou of Rouen and William of Santa Cecilia, the King performed public penance and swore to provide 200 knights for the defense of the Holy Land.16 However, a closer reading of the carta reconciliationis reveals that Henry managed to preserve the core of his administrative power through strategic linguistic drafting.

The most significant concession in the Compromise was the annulment of Article 8 of the Constitutions of Clarendon, which had prohibited appeals to Rome without royal consent.19 Henry swore that he would not impede such appeals in ecclesiastical causes, effectively opening the door for direct papal intervention in the English legal system.1 Yet, even here, he secured a caveat: he retained the right to require security from any "suspect" appellants to ensure they were not seeking to harm the King or the realm.7 This allowed for continued royal monitoring of the correspondence between English prelates and the Roman Curia.

The masterstroke of the Avranches settlement lay in the fourth clause, which required Henry to "utterly abrogate the customs that were introduced against the churches of your lands during your time".19 By successfully negotiating the inclusion of the phrase "during your time," Henry exploited a critical loophole. Throughout the Becket controversy, he had insisted that the Constitutions of Clarendon were not new innovations but were the "ancestral customs" of Henry I.1 Consequently, the King could argue that the vast majority of the 1164 articles were not "introduced during his time" and therefore remained in full force.2 This ambiguity allowed Henry to appear submissive to the Pope while maintaining the institutional structures he had fought to codify.

Comparison of Pre-1170 Aims and Post-1172 Reality

Aim of Henry II (1164)	Clause in 1172 Compromise	Actual Outcome/Status
Eliminate unhindered appeals to Rome (Art. 8)	Formally annulled; appeals permitted.19	Royal power restricted, but "suspect" appellants still monitored.1
Subject criminous clerks to secular punishment (Art. 3)	Renounced secular jurisdiction over most clerical crimes.21	Clerical immunity established for felonies, except forest laws.12
Assert royal control over "ancestral customs"	Abrogate "new" customs introduced in his time.19	Ambiguity allowed retention of 14 out of 16 articles.2
End the papal schism for leverage	Swear allegiance to Alexander III.19	Lost the ability to threaten defection to the antipope.22
Control of episcopal elections (Art. 12)	Not explicitly mentioned as annulled.6	Retained practical control over elections in the royal chapel.5

The Agreement of Westminster 1176: Practical Refinements

The reconciliation process continued through the 1170s, culminating in the Agreement of Westminster in 1176. This agreement provided the specific administrative details that had been left vague at Avranches, particularly concerning the limits of clerical immunity and the King’s financial interests in the Church. While Henry formally accepted the "benefit of clergy"—the principle that no clerk could be brought before a temporal judge for a crime—he secured vital exceptions that protected his most essential royal prerogatives.6

The 1176 settlement established that clerical immunity did not apply to offenses against the forest laws.12 This was a significant victory for Henry II, as the royal forests were a massive source of revenue and personal authority, often covering entire counties.23 Furthermore, the King retained jurisdiction over cases involving lay fees—lands held by the Church but for which secular service was due to the Crown.13 These exceptions ensured that the Church could not become a sanctuary for those who threatened the King’s economic or territorial interests.

Another key component of the 1176 agreement was the King's pledge not to keep vacant archbishoprics, bishoprics, or abbeys "in his hand" for more than one year, unless necessitated by an "urgent cause".13 This addressed Article 12 of the Constitutions, which had given the King control over the revenues of vacant sees.9 While this appeared to be a concession, the "urgent cause" clause provided sufficient flexibility for the King to continue exploiting these vacancies when politically or financially necessary.

The Persistence of Royal Prerogative in Advowsons and Elections

Perhaps the most significant evidence of Henry II’s success is the survival of Article 1 of the Constitutions, which placed the right of advowson—the presentation of clergy to benefices—under the jurisdiction of the King’s court.1 Despite the intense pressure from the Papacy to bring these matters under canon law, Henry never relinquished this power. Control over advowsons was essential for maintaining the loyalty of the aristocracy and the lower clergy, as it allowed the King and his barons to use ecclesiastical appointments as a form of patronage and reward.5 By keeping these disputes in secular courts, Henry ensured that the material and legal foundations of the Church remained tethered to royal authority.24

Similarly, the King’s influence over episcopal elections remained largely intact. Although he abandoned the practice of formal investiture (the giving of the ring and staff), he retained the right to require "feudal homage" from elected prelates.6 The election process itself continued to take place in the royal chapel, often in the King’s presence, which allowed him to exert immense pressure on the electors to choose candidates favorable to the Crown.5 This "Revised Clarendon model" prioritized cooperation over confrontation, leading to a period of relatively amicable relations between Henry and Becket’s successor, Richard of Dover.19

The Status of Criminous Clerks: A Bifurcated Legal Reality

The treatment of "criminous clerks" after 1172 represents one of the most complex legacies of the Becket controversy. While the King formally dropped Article 3, the reality was a hybrid system where the secular and ecclesiastical courts operated in tandem. When a cleric was accused of a felony, he would be arrested by the sheriff but then "claimed" by the bishop for trial in an ecclesiastical court.12 If the clerk was found guilty, he was degraded from his orders and lost his clerical status. Under the new agreement, if that same individual committed a second crime, he was then treated as a layman and subject to the full weight of secular law, including capital punishment.2

This compromise effectively established a "first offense" immunity. While this was a victory for the Church's principle of the privilegium fori (privilege of the court), it also provided the King with a mechanism to eventually punish persistent offenders among the clergy.12 Furthermore, the secular courts were responsible for determining if the accused was indeed a clerk—often through a "reading test"—which maintained a level of royal oversight at the very start of the judicial process.13

Post-1172 Judicial Practice for Criminous Clerks

Stage of Legal Process	Jurisdiction	Procedural Detail
Arrest for Felony	Secular (Sheriff)	The King's officers were responsible for the initial apprehension.13
Verification of Status	Secular Court	The court determined if the defendant was entitled to "benefit of clergy".13
Trial for First Offense	Ecclesiastical Court	Conducted through compurgation (swearing of oaths with witnesses).12
Punishment (Guilty)	Ecclesiastical Court	Degradation, suspension, or imprisonment in a monastic cell.6
Corporal Punishment	Secular (Post-Degradation)	Only applicable if a second offense was committed after losing status.2
Exception: High Treason	Secular Court	Immunity did not apply to cases of treason or highway robbery.21
Exception: Forest Law	Secular Court	Clerics remained fully subject to the King's forest justices.12

Second and Third-Order Insights: The Institutional Evolution

Beyond the immediate legal changes, the aftermath of the Becket martyrdom triggered a profound institutional evolution in England. The King’s initial attempt to forcibly subordinate the Church in 1164 was replaced by a more sophisticated "legalistic" approach. This transition from overt aggression to administrative integration is visible in the drafting of the Tractatus de legibus et consuetudinibus regni Angliae (the Treatise on the Laws and Customs of the Kingdom of England), attributed to Ranulf de Glanvill, which was written toward the end of Henry’s reign.11

One of the most profound third-order effects of this conflict was the strengthening of the English Common Law. Henry II’s efforts to reclaim royal rights led to the development of the "Assize of Clarendon" (not to be confused with the Constitutions), which established the jury of presentment—the ancestor of the modern grand jury.5 By standardizing legal procedures to combat clerical and baronial lawlessness, the King inadvertently created a centralized judicial system that became the defining feature of the English state.5 The conflict with Becket forced the Crown to define its powers more precisely, leading to a "quiet non-aggression pact" where the two systems of law—common and canon—existed as equally normative but clearly limited in their respective scopes.11

The martyrdom itself, while a personal and political blow to Henry, acted as a catalyst for a more sustainable "working model" of Church-State relations.26 The shock of the murder forced both the Papacy and the Crown to abandon extreme positions. Alexander III, realizing the value of Henry as a bulwark against other European rivals like Frederick Barbarossa, was willing to accept a degree of ambiguity in the English settlement.22 In turn, Henry recognized that he could achieve most of his objectives through administrative control and the manipulation of legal procedure rather than through the direct legislative attack that had characterized the early 1160s.19

Synthesis of Outcomes: Success or Failure?

In evaluating whether Henry II succeeded or failed in his aims, the distinction between symbolic surrender and administrative retention is paramount. Henry certainly failed in his goal of establishing a completely self-contained national church immune to papal appeal.19 He was forced to publicly humiliate himself through penance and to abandon his plan to punish criminous clerks in secular courts for their first offenses.14

However, in the broader context of governance and royal authority, Henry II emerged remarkably successful. By using the "ancestral customs" clause to preserve fourteen of the sixteen articles of Clarendon, he ensured that the English monarchy retained control over the most vital aspects of the Church’s temporal existence—its lands, its patronage (advowsons), and its political leadership (elections).2 The exceptions he carved out in 1176 regarding forest laws and lay fees demonstrated his ability to protect the Crown’s economic interests even while granting spiritual concessions.13

The long-term result was a "broad accommodation" between the Crown and the Mitre that characterized the rest of Henry’s reign.19 The Church became a separate estate with its own laws, but it remained firmly integrated into the feudal and administrative structures of the Angevin Empire.6 The martyrdom of Thomas Becket secured the "benefit of clergy," but it did not halt the expansion of royal jurisdiction that Henry II had initiated. In many ways, the compromise reached at Avranches and Westminster provided a more stable foundation for the English state than the rigid and confrontational articles of 1164 ever could have.26

The Status of the 16 Articles after 1176

Article Category	Post-1176 Status	Level of Royal Success
Direct Control (Art. 1, 2, 9, 15, 16)	Remained in secular courts; fully operational.1	High: These formed the backbone of royal property and debt law.
Administrative Links (Art. 4, 7, 10, 11)	Largely survived through custom and feudal duty.3	High: Bishops remained royal barons with feudal obligations.
Financial Interests (Art. 12, 14)	Modified by the "one-year" vacancy limit but revenues still captured.13	Moderate: Retained significant financial exploitation potential.
Criminal Jurisdiction (Art. 3, 5, 6, 13)	Formally dropped for first offenses; immunity granted.2	Low: The specific goal of Article 3 was explicitly renounced.
Papal Authority (Art. 8)	Annulled; appeals to Rome allowed.19	Low: Henry lost the ability to legally block contact with the Pope.

Detailed Breakdown of the Articles and the Mechanism of Compliance

The historical significance of Henry II's engagement with the Church rests not only on the outcomes of high-level diplomatic summits like Avranches but also on the daily mechanical application of the sixteen articles. To understand the extent of Henry’s success, one must delve into the specific legal processes that survived the 1170 crisis. The King’s strategy was to embed royal prerogative so deeply into the emerging common law that the Church could not extract itself without destabilizing the entire legal framework of the kingdom.

Article 1: The Sovereignty of Advowson

Disputes over the right of patronage—who held the power to present a clerk to a specific church—were fundamentally property disputes. Henry II insisted in Article 1 that these controversies be "treated of and terminated in the court of the lord king".1 This was perhaps his most enduring victory. After 1172, the King did not back down on this claim. The Church argued that because the presentation involved spiritual office, it belonged in ecclesiastical courts. Henry countered that because it involved the endowment of land (the "fee"), it was a secular matter.1 By the end of the twelfth century, the writ of Darrein Presentment and the Assize of Darrein Presentment were established parts of royal law, effectively keeping church appointments under secular oversight.24 This ensured that the King and his barons could continue to use the Church's vast network of benefices to reward loyal servants and maintain social control.5

Article 9: The Assize Utrum and Jurisdictional Thresholds

Article 9 introduced a revolutionary procedural mechanism: the recognition of twelve "lawful men" to determine whether a particular tenement was "alms" (held by the church in free alms) or a "lay fee".1 This became known as the Assize Utrum. Even after Becket’s death, this article remained a cornerstone of English law. It established the King's court as the gateway to jurisdiction; only after the royal inquest determined the nature of the tenure could the case proceed to either the ecclesiastical or royal court.1 This allowed the Crown to act as the primary arbiter of legal categorization, a massive third-order success that effectively capped the expansion of Church landholdings under protected spiritual tenures.11

Article 12: Financial Extraction and the Revised Clarendon Model

One of the primary drivers of Henry’s policy was financial necessity.27 Article 12 explicitly stated that when an archbishopric, bishopric, or abbey fell vacant, it should be in the King's hand, and he should receive all the rents and revenues from it.1 While the Agreement of Westminster in 1176 appeared to limit this by promising not to hold vacancies for more than a year, the King successfully negotiated an exception for "urgent cause".13 Historians such as W.L. Warren have noted that Henry continued to use these revenues to fund his vast military and administrative needs.22 Furthermore, by requiring the election to take place in the royal chapel with the King’s consent, Henry ensured that the new prelate was someone who had already performed "feudal homage" and "allegiance" to the Crown, effectively neutralizing the independence of the high clergy.5

The Evolution of Clerical Immunity: From Article 3 to Benefit of Clergy

The most dramatic area of "failure" for Henry was Article 3, which had proposed that criminous clerks be tried in secular courts and handed over for punishment like any other felon.1 Becket's martyrdom made this politically impossible to enforce in its original form. However, the resulting evolution of "benefit of clergy" was a testament to Henry’s ability to compromise without losing total control.

The 1176 Agreement of Westminster mandated that no clerk be brought in person before a temporal judge for any crime.13 Yet, the mechanism of this immunity was highly structured. The secular court would first arrest the individual and then hand them over to the bishop only after their clerical status was confirmed.13 If the clerk committed a second offense after being degraded, the King's court could then execute him.2 This created a bifurcated reality: the Church won the battle over the cleric's body for the first offense, but the King won the battle over the law of the land by ensuring that "lawlessness" could still be eventually met with the sword.1

Furthermore, the forest law exception was a massive strategic victory for the Crown. The King’s forests were not merely ecological zones but a parallel legal system where royal will was absolute.23 By keeping clerics subject to the forest justices, Henry ensured that a huge portion of his subjects (including the clergy who frequently hunted or harvested wood) remained directly answerable to royal authority.12

The Role of International Diplomacy and the Papal Schism

The extent of Henry's success cannot be analyzed in isolation from the broader European political landscape. Pope Alexander III was locked in a bitter schism with Emperor Frederick Barbarossa, who supported a series of antipopes.22 Henry used this to his advantage, frequently threatening to transfer his allegiance to the antipope if Alexander did not rein in Becket.22 Before 1170, this leverage was highly effective, forcing the Pope to walk a fine line between supporting his archbishop and not alienating a powerful King.6

The martyrdom of 1170 momentarily destroyed this leverage. Henry was forced to swear an oath of allegiance to Alexander III and his successors, effectively closing the door on any further flirtation with the German schismatics.19 However, once the initial heat of the martyrdom cooled, the Pope’s own pragmatic needs resurfaced. Alexander was eager to bring England back into the fold to stabilize his own position in Europe. This led to the "Revised Clarendon" model where the Pope became an "optional participant" in English ecclesiastical affairs rather than a constant interventionist.31 The Papacy often agreed to Henry’s royal appointments in exchange for his continued support of the Roman Curia.32

Conclusion: The Nuanced Victory of the Angevin State

Henry II’s achievement regarding the Constitutions of Clarendon after 1170 was a triumph of pragmatic statecraft over ideological purity. While the martyrdom of Thomas Becket forced a tactical retreat on the high-profile issues of "criminous clerks" and "appeals to Rome," the King successfully protected the "ancestral customs" that defined the underlying power structure of the realm. The Compromise of Avranches was not the end of Henry’s ecclesiastical policy but the beginning of its maturation. By incorporating the Church into the burgeoning Common Law system through writs, inquests, and jurisdictional boundaries, Henry II ensured that the English Crown would remain the ultimate arbiter of earthly affairs within its dominions. The ultimate legacy of the conflict was not the defeat of the King, but the creation of a more resilient, legalistic, and centralized monarchy that would define the English constitutional landscape for centuries to come.
