Archbishopric
On the death of Hubert Walter, Archbishop of Canterbury, in 1205, some of the younger monks elected to the see Reginald, the subprior of Christ Church, Canterbury, while another faction under pressure from King John chose John de Grey, Bishop of Norwich. Both elections were quashed on appeal to Rome and sixteen monks of Christ Church, who had gone to Rome empowered to act for the whole chapter, were ordered to proceed to a new election in presence of the Pope. Langton was chosen and was consecrated by the Pope at Viterbo on 17 June 1207.
There followed a hard political struggle between John of England and Pope Innocent III. The King proclaimed as a public enemy anyone who recognized Stephen as Archbishop. On 15 July 1207, John expelled the Canterbury monks, who were now unanimous in support of Stephen. In March 1208, Pope Innocent III placed England under interdict and at the close of 1212, after repeated negotiations had failed, he passed sentence of deposition against John, committing the execution of the sentence to Philip II of France in January 1213.
In May 1213 King John yielded and thus in July, Stephen (who since his consecration had lived at Pontigny Abbey in Burgundy) and his fellow exiles returned to England. His first episcopal act was to absolve the King, who swore that unjust laws should be repealed and the liberties granted by Henry I should be observed—an oath which he almost immediately violated.
Stephen now became a leader in the struggle against King John. At a council of churchmen at Westminster on 25 August 1213, to which certain barons were invited, he read the text of the charter of Henry I and called for its renewal. In the sequel, Stephen's energetic leadership and the Barons' military strength forced John to sign the Magna Carta (15 June 1215).
Since King John now held his kingdom as a fief of the Holy See the Pope espoused his cause and excommunicated the barons. For refusing to publish the excommunication Stephen was suspended from all ecclesiastical functions by the papal commissioners and on 4 November this sentence was confirmed by the Pope, although Stephen appealed to him in person. He was released from suspension the following spring on condition that he keep out of England until peace was restored, and he remained abroad till May 1218. Meanwhile both Pope Innocent and King John died and all parties in England rallied to the support of Henry III.
Stephen Langton continued under Henry's reign to work for the political independence of England. In 1223 he again appeared as the leader and spokesman of the barons, who demanded that King Henry confirm the charter. He went to France on Henry's behalf to call on Louis VIII of France for the restoration of Normandy, and later he supported Henry against rebellious barons. He obtained a promise from the new pope, Honorius III, that during his lifetime no resident legate should be again sent to England, and won other concessions from the same pontiff favorable to the English Church and exalting the see of Canterbury.
Of great importance in the ecclesiastical history of England was a council which Stephen opened at Osney on 17 April 1222; its decrees, known as the Constitutions of Stephen Langton, are the earliest provincial canons which are still recognized as binding in English church courts.
