The Becket controversy or Becket dispute was the quarrel between Archbishop of Canterbury Thomas Becket and King Henry II of England from 1163 to 1170.Bartlett England Under the Norman and Angevin Kings pp. 401–402 The controversy culminated with Becket's murder in 1170,Huscroft Ruling England pp. 140–141 and was followed by Becket's canonization in 1173 and Henry's public penance at Canterbury in July 1174.Barlow Thomas Becket pp. 269–270

The dispute concerned the respective rights of crown and church. The king attempted to reassert royal prerogatives and the archbishop resisted. A significant point of contention was jurisdiction over criminal cases regarding clerics, even if only in minor orders. The matter dragged on for a number of years as both sides appealed to the pope, who attempted to bring the parties to a negotiated settlement, but to no avail. Both sides resorted to actions that escalated the dispute with the king confiscating property and the archbishop issuing excommunications.

Background

King Henry II appointed his chancellor, Thomas Becket, as Archbishop of Canterbury in 1162. This appointment was made to replace Theobald of Bec, the previous archbishop, who had died in 1161. Henry hoped that by appointing his chancellor, with whom he had very good relations, royal supremacy over the English Church would be reasserted, and royal rights over the Church would return to what they had been in the days of Henry's grandfather, King Henry I of England.Huscroft Ruling England pp. 192–195

Start of the dispute

However, shortly after Becket's consecration, the new archbishop resigned the chancellorship and changed his entire lifestyle. Previously, Becket had lived ostentatiously, but he now wore a cilice and lived like an ascetic. That said, modern Becket historian Frank Barlow argues that the stories of Becket immediately wearing a hair shirt are later embellishments.Barlow Thomas Becket p. 75 He also no longer aided the king in defending royal interests in the church, but instead began to champion ecclesiastical rights.

Although a number of small conflicts contributed to the controversy, the main source of conflict was over what to do with clergy who committed secular crimes. Because even those men who took minor orders were considered clergy, the quarrel over the so-called "criminous clerks" potentially covered up to one-fifth of the male population of England at the time. Becket held the position that all clergy, whether only in minor orders or not, were not to be dealt with by secular powers, and that only the ecclesiastical hierarchy could judge them for crimes, even those that were secular in nature (the benefit of clergy). Henry, however, felt that this position deprived him of the ability to govern effectively, and also undercut law and order in England. Henry held that the laws and customs of England supported his position, and that Theobald of Bec, the previous archbishop, had admitted in 1154 to the papacy that the English custom was to allow secular courts to try clerks accused of crimes.Alexander "Becket Controversy" Journal of British Studies pp. 2–4, 12

Among the other issues between the king and the archbishop were the actions Becket took to recover lands lost to the archdiocese, some of which he reacquired with a royal writ that authorized the archbishop to restore any alienated lands. His high-handedness caused many complaints to the king, and added to the dispute.Barlow Thomas Becket pp. 83–84 Another disagreement involved Henry's attempts to collect sheriff's aid in 1163. Becket argued that the aid was a free will offering to the sheriffs, and could not be compelled. This culminated in a heated argument at Woodstock, Oxfordshire, in July 1163.Barlow Thomas Becket pp. 88–89 Yet another contributing factor was Becket's excommunication of a royal tenant-in-chief who had resisted the archbishop's attempt to install a clerk in a church where the tenant claimed the right to name the appointment. A still later quarrel between the king and Becket resulted in Becket giving way to the king's statement that the custom of England was that no tenant-in-chief could be excommunicated without royal permission.Barlow Thomas Becket pp. 93–94

Build-up to exile

In October 1163, Henry summoned the ecclesiastical hierarchy to Westminster to hear his complaints about the governance of the English Church. At first, the bishops did not agree with the king, who then asked them if they would agree to observe the ancient customs of England. The bishops remained steadfastly behind Becket, and refused to agree to observe the customs if they conflicted with canon law. The council only met for a day, and the next day, the king took his heir, Henry the Young King, out of Becket's custody, as well as confiscating all the honours that he had formerly given to Becket. This was effectively a dismissal of Becket from royal favour.Barlow Thomas Becket p. 95

Over the next year, both sides manoeuvered to gain advantages, working on diplomatic efforts to secure allies. The king, advised by Arnulf of Lisieux, worked on the bishops and managed to swing many of them over to his viewpoint. Both sides petitioned the papacy, and Becket also sent diplomatic feelers to King Louis VII of France and Frederick Barbarossa, the Holy Roman Emperor. The pope, Alexander III, refused to take sides, and urged moderation on both sides. Becket also began to secure possible safe places of refuge on the continent, if he should need to go into exile.Barlow Thomas Becket pp. 96–98

In late January 1164, the king summoned his major barons as well as the bishops to Clarendon Palace for a council. Once it assembled, the king demanded that the bishops and Becket swear to uphold without reservations the customs of the church as they had been in the king's grandfather's reign. At first, Becket refused, but threats and other arguments eventually persuaded him to support the customs, and Becket then ordered the remaining bishops to assent also. The king then proposed to have a committee of barons and clerks compile these customs into a written document, which would be presented to the council. This was done, but in the middle of the recitation of the customs, Becket asked for a postponement in order for him to consult with others about the customs. He verbally assented to uphold the ancient customs, and the other bishops reluctantly did the same. The king demanded the bishops affix their personal seals to a written parchment of the Constitutions of Clarendon, which was then produced. Becket refused, stating that he promised to observe the customs but not give them this ultimate sanction. He said he needed to consult with the Pope before taking such a step.Barlow Thomas Becket pp. 98–100

In August 1164, Becket attempted to go to France without permission, which was forbidden by the Constitutions. He was caught, and then tried on 6 October 1164 at a royal court on different charges of failing to adequately address a suit brought against him by nobleman John Marshal about lands that Becket had confiscated. Once at the council, Becket was found guilty of ignoring the court summons and under pressure from the bishops, accepted the sentence of confiscation of all non-landed property pending the pleasure of the king. However, the original dispute over John Marshal's lands was decided in the archbishop's favour. The king then brought further charges and asked for an accounting of Becket's spending while the archbishop had been chancellor. Another charge was that he was not fulfilling his oath to observe the Constitutions. Becket replied that he was not prepared to answer those charges and was eventually found guilty of both. The archbishop refused to accept the sentence, and fled Northampton and took sanctuary.Barlow Thomas Becket pp. 108–114

Exile

Thomas took a ship to the continent on 2 November 1164,Barlow Thomas Becket p. 116 eventually reaching a resting spot at Sens, where both sides presented their cases to Alexander. Although Becket was not ordered back to England as the king's envoys requested, neither was the king ordered to back down. Instead, Becket went into exile at Pontigny. Afterward, the king confiscated all the benefices of the archbishop's clerks, who had accompanied him into exile. The king also ordered the exile of Becket's family and servants.Barlow Thomas Becket pp. 121–126

While in exile, Becket engaged in letter writing, writing to many English noblemen and bishops. He engaged in a series of letter exchanges with Gilbert Foliot, the Bishop of London, who was also the recipient of letters from the pope. Becket continued to attempt to resolve the dispute, but Alexander ordered the archbishop to refrain from provoking the king before spring 1166.Barlow Thomas Becket pp. 137–138 Meanwhile, Henry had delegated much of the everyday business of the English Church to Foliot, who although supportive of the king was no compliant supplicant, and was known as a supporter of papal positions. Neither Foliot nor Henry had any great desire to settle with Becket quickly.Barlow Thomas Becket p. 140

In late spring 1166, Becket began to threaten the king with ecclesiastical punishments if he did not settle with him. Henry ignored the initial warning letters, but Becket's position was strengthened by the grant to Becket of the status of a papal legate to England, dated on 2 May 1166. On Whitsun 1166, Becket excommunicated a number of Henry's advisers and clerical servants, including John of Oxford, Richard of Ilchester, Richard de Lucy, and Jocelin de Balliol, among others.Barlow Thomas Becket pp. 144–148 A bishop was also excommunicated, Josceline de Bohon, the Bishop of Salisbury.Barlow Thomas Becket pp. 149–151

The king and Foliot responded to these actions with the summoning of a council that was held at London around 24 June 1166. The council sent letters both to the pope and to Becket, appealing against the excommunications. After the dispatch of these letters, letters from the archbishop were delivered to Foliot, ordering him to publicize Becket's decisions, and disallowing any appeal to the papacy against the archbishop's sentences. Foliot and the bishops then once again sent letters to the papacy, probably from Northampton on 6 July. A more concrete effort was the appeal of the king to the Cistercian Order's general convocation in 1166, protesting at the aid the Cistercian monasteries of Pontigny, Cercamp and Rigny had given to Becket and threatening to expel the order from Henry's lands. Although the Order did not exactly expel Becket from Pontigny, a delegation of Cistercians did meet Becket, pointing out that while they would not throw him out, they felt sure that he would not wish to bring harm to the Order. Becket then secured aid from the king of France, who offered a sanctuary at Sens.Barlow Thomas Becket pp. 157–158
