It is evident from this passage that the Schools at Oxford were by this time of considerable note and size. There was a University here now in fact if not in name or by charter. A few years later the records reveal to us the first known student in it. He was a clerk from Hungary named Nicholas, to whom Richard I. who had been born in the Palace of Beaumont, made an allowance of half a mark weekly for his support during his stay at Oxford for the purpose of study. Thus, then, by the beginning of the reign of King John, we may be sure that there was established at Oxford a University, or place of general study, and this University had attracted to itself an academic population, which was estimated by contemporaries at no less than three thousand souls. And now, just as the country won its Great Charter of Liberties from that oppressive and intolerable Angevin monarch, so documentary evidence of the independent powers of the University was first obtained, as the result of a series of events, in which the citizens of Oxford had been encouraged to commit an act of unjust revenge by their reliance on John's quarrel with the pope and the clergy. The pope had laid the whole country under an interdict; the people were forbidden to worship their God and the priests to administer the sacraments; the church-bells were silent and the dead lay unburied on the ground. The King retaliated by confiscating the land of the clergy who observed the interdict, by subjecting them in spite of their privileges to the Royal Courts, and often by leaving outrages on them unpunished. "Let him go," he said, when a Welshman was brought before him for the murder of a priest, "he has killed my enemy." Such were the political conditions, when at Oxford a woman of the town was found murdered in circumstances which pointed to the guilt of a student. The citizens were eager for vengeance, and they took the matter into their own hands (1209). The offender had fled, but the mayor and burgesses invading his hostel arrested two innocent students who lodged in the same house. They hurried them outside the walls of Oxford, and, with the ready assent of John, who was then at Woodstock, hung them forthwith. This was a defiance of ecclesiastical liberty. For it was a chief principle of the Church that all clerks and scholars, as well as all higher officials in the hierarchy, should be subject to ecclesiastical jurisdiction alone. For this principle Becket had died, and in defence of this principle a quarrel now arose between the University and the town which bade fair to end in the withdrawal of the former altogether from Oxford. In protest the masters and scholars migrated from the town, and transferred their schools to Paris, to Reading and to Cambridge. It is, indeed, to this migration that the Studium Generale on the banks of the Cam may owe its existence.
