In the year 1229 there broke out at Paris a feud of more than ordinary gravity between the students and the citizens, undignified enough in its cause of origin, but in the event probably marking a distinct step in the development of Cambridge University. A drunken body of students did some act of great violence to the citizens. Complaint was made to the Bishop of Paris and to the Queen Blanche. The members of the University who had not been guilty of the outrage were violently attacked and ill-treated by the police of the city. The University teachers suspended their classes and demanded satisfaction. The demand was refused, and masters and scholars dispersed. Large numbers, availing themselves of the invitation of King Henry III. to settle where they pleased in this country, migrated to the shores of England; and Cambridge, probably from its proximity to the eastern coast, and as the centre where Prince Louis, in alliance with the English baronage, but a few years before had raised the Royal standard, seems to have attracted a large majority of the students. A Royal writ, issued in the year 1231, for the better regulation of the University, probably makes reference to this migration when it speaks of the large number of students, both within the realm and "from beyond the seas," who had lately settled in Cambridge, and gives power to the Bishop of Ely "to signify rebellious clerks who would not be chastised by the Chancellor and Masters," and if necessary to invoke the aid of the Sheriff in their due punishment. Another Royal writ of the same reign expressly provides that no student shall remain in the University unless under the tuition of some Master of Arts--the earliest trace perhaps of that disciplinary organisation which the motley and turbulent crowd representing the student community of that age demanded.[19] It will be observed that in these Royal writs the term "university" occurs. But it must not be supposed that the word is used in its more modern signification, of a community or corporation devoted to learning and education formally recognised by legal authority. That is a use which appears for the first time towards the end of the fourteenth century. In the age of which we are speaking, and in the writs of Henry III., _universitas magistrorum et discipulorum_ or _scholarium_ simply means a "community of teachers and scholars." The common designation in mediæval times of such a body as we now mean by "university" was _studium generale_, or sometimes _studium_ alone. It is necessary, moreover, to remember that universities in the earliest times had not infrequently a very vigorous life as places of learning, long before they received Royal or legal recognition; and it is equally necessary not to forget that colleges for the lodging and maintenance and education of students are by no means an essential feature of the mediæval conception of a university.
