Upon his return to England John became involved in a conflict with Pope Innocent III over the choice of an archbishop. At Hubert Walter’s death in 1205 the monks at Canterbury had secretly elected their subprior and sent him to Rome to receive the pallium from the pope. The secret got out, however, and John forced the election of one of his confidants, John de Grey, bishop of Norwich, who then was also sent to Rome. Innocent III was not a man to miss such a good opportunity to demonstrate the plenitude of papal power. He quashed both elections and engineered the election of the learned and talented cardinal Stephen Langton. John, however, refused to receive Stephen and seized the revenues of Canterbury. Since John had already quarreled with his half brother the archbishop of York, who had fled abroad, England was without either archbishop. In 1208 Innocent imposed an interdict on England, forbidding the administration of the sacraments and certain church rites. In the following year he excommunicated John. The bishops of Winchester and Norwich remained the sole support of John’s power in the church. John made the most of the opportunity to collect the revenues of the sees vacated by bishops who had gone into exile.
In theory John’s excommunication freed his vassals from their oaths of fealty to him, but there was no immediate rebellion. John was able to conduct highly successful expeditions to Scotland, Wales, and Ireland, and it was not until 1212 that a plot, involving Robert Fitzwalter and Eustace de Vesci, was first hatched against the king. John’s brilliant solution to the problem of multiple threats was to effect a reconciliation with the papacy. He agreed to accept Stephen Langton as archbishop, to reinstate the exiled clergy, and to compensate the church for his exactions. In addition he surrendered his kingdom to the pope, receiving it back as a fief from the pope. He now had an able ally at no great cost in terms of concessions on his part.
Revolt of the barons and Magna Carta
Ever since the loss of Normandy John had been building up a coalition of rulers in Germany and the Low Countries to assist him against the French king. His chief ally was Otto IV, king of Germany and Holy Roman emperor. Plans for a campaign in Poitou proved very unpopular in England, especially with the northern barons. In 1214 John’s allies were defeated at Bouvines, and the king’s own campaign in Poitou disintegrated. John had to withdraw and return home to face his disgruntled barons.
John’s efforts had been very costly, and measures such as the tax of a 13th in 1207 (which raised about £60,000) were highly unpopular. In addition John levied massive reliefs (inheritance duties) on some barons: Nicholas de Stuteville, for example, was charged 10,000 marks (about £6,666) to inherit his brother’s lands in 1205. The fact alone that John, unlike his predecessors on the throne, spent most of his time in England made his rule more oppressive. Resistance sprang chiefly from the northern barons who had opposed service in Poitou, but by the spring of 1215 many others had joined them in protest against John’s abuse or disregard of law and custom.
