The twelfth century produced in Europe a renewal of interest and a revival of learning, brought about partly by the influence of great thinkers like St Anselm and Abelard, and partly by the discovery of lost works of Aristotle. The impulse thus given to study resulted in an increase in the numbers of students, and students were naturally attracted to schools where masters and teachers possessed, or had left behind them, great names. At Bologna there was a great teacher of the Civil Law in the first quarter of the twelfth century, and a great writer on Canon Law lived there in the middle of the same century. To Bologna, therefore, there flocked students of law, though not of law alone. In the schools of Paris there were great masters of philosophy and theology to whom students crowded from all parts of Europe. Many of the foreign students at Paris were Englishmen, and when, at the time of Becket's quarrel with Henry II., the disputes between the sovereigns of England and France led to the recall of English students from the domain of their King's enemy, there grew up at Oxford a great school or Studium, which acquired something of the fame of Paris and Bologna. A struggle between the clerks who studied at Oxford and the people of the town broke out at the time of John's defiance of the (p. 007) Papacy, when the King outlawed the clergy of England, and this struggle led to the rise of a school at Cambridge. In Italy the institutions of the Studium at Bologna were copied at Modena, at Reggio, at Vicenza, at Arezzo, at Padua, and elsewhere, and in 1244 or 1245 Pope Innocent IV. founded a Studium of a different constitution, in dependence upon the Papal Court. In Spain great schools grew up at Palencia, Salamanca, and Valladolid; in France at Montpellier, Orleans, Angers, and Toulouse, and at Lyons and Reims. The impulse given by Bologna and Paris was thus leading to the foundation of new Studia or the development of old ones, for there were schools of repute at many of the places we have mentioned before the period with which we are now dealing (_c._ 1170-1250). It was inevitable that there should be a rivalry among these numerous schools, a rivalry which was accentuated as small and insignificant Studia came to claim for themselves equality of status with their older and greater contemporaries. Thus, in the latter half of the thirteenth century, there arose a necessity for a definition and a restriction of the term Studium Generale. The desirability of a definition was enhanced by the practice of granting to ecclesiastics dispensations from residence in their benefices for purposes of study; to prevent abuses it was essential that such permission should be limited to a number of (p. 008) recognised Studia Generalia.
