The next generation saw Augustinian Canons settled in the town itself, at the Hospital (now the College) of St. John; and Benedictine nuns at the Priory of St. Radegund just beyond the King's Ditch, where their conventual church is still used as the Chapel of Jesus College. A century later, and friars of all the Orders came flocking into Cambridge; the Grey Franciscans, the Black Dominicans, the White Carmelites, the Austin Friars, the Friars of the Sack, the Friars of Bethlehem. The sites occupied by the first three of these names are to-day represented by the Colleges of Sidney, Emmanuel, and Queens'. Friars always made for the chief centres of life, and by the thirteenth century Cambridge had become emphatically such, by the rise of that institution destined to give it a perennial fame, the University. How this rise of the University came about is an as yet unsolved problem in history. As in the case of Oxford, the great name of Alfred was invoked, by unscrupulous mediaeval fabricators, as concerned in its foundation. And it is possible that there may be really traceable some distant connection with that great saint and hero. For Alfred actually did found amidst the ruins of Ely, after its sack by the Danes, a small College of priests, which lived on to be the nucleus of the restored Abbey in the days of his grandson Edgar the Peaceful. And it is also historical fact that this restored Abbey was specially renowned for the famous school attached to it--so famous as to count amongst its scholars more than one future monarch. Furthermore we know that the Ely monks taught in Cambridge also, and this may well have been the first germ of the University. At any rate it is certain that, in 1209, when the schools of Oxford were for a while closed by the Government, as the outcome of a more than usually outrageous "rag," large numbers of the students migrated to Cambridge; which seems to point to the place having already some educational repute. From henceforward, at all events, it attained European reputation in this respect, for, in 1229, we find another batch of expelled students, this time from Paris, settling themselves here, and yet another swarm of Oxonians twenty years later. The University had now become an organic body, with its Chancellor, its masters, and its scholars or "clerks," so called because, being not wholly illiterate, the Law considered them as potential members of the clerical profession, and gave them special immunities accordingly. They were not amenable to lay jurisdiction, but only to the milder "Courts Christian," in which the death-penalty was never inflicted. It seems not infrequently to have been deserved; for the earliest undergraduates were, at first, an utterly lawless lot, and made themselves most unpleasant neighbours to the "burgesses" of the Town.
