There were about 1,500 students in Oxford. They drank, played dice, quarreled a lot and begged at street corners. There were mob fights between students from the north and students from the south and between students and townsmen. But when the mayor of Oxford hanged two students accused of being involved in the killing of a townswoman, many masters and students left for Cambridge. In 1214, a charter created the office of Chancellor of the university at Oxford. He was responsible for law and order and, through his court, could fine, imprison, and excommunicate offenders and expel undesirables such as prostitutes from the town. He had authority over all crimes involving scholars, except murder and mayhem. The Chancellor summoned and presided over meetings of the masters and came to be elected by indirect vote by the masters who had schools, usually no more than a room or hall with a central hearth which was hired for lectures. Students paid for meals there. Corners of the room were often partitioned off for private study. At night, some students slept on the straw on the floor. Six hours of sleep were considered sufficient. In 1231, the king ordered that every student must have his name on the roll of a master and the masters had to keep a list of those attending his lectures. In 1221 the friars established their chief school at Oxford. They were bound by oaths of poverty, obedience, and chastity, but were not confined within the walls of a monastery. They walked barefoot from place to lace preaching. They begged for their food and lodgings. They replaced monks, who had become self-indulgent, as the most vital spiritual force among the people. The first college was founded in 1264 by Walter de Merton, former Chancellor to the King, at Oxford. A college had the living arrangements of a Hall, with the addition of monastic-type rules. A warden and about 30 scholars lived and ate meals together in the college buildings. Merton College's founding documents provided that: [1] "The house shall be called the House of the Scholars of Merton, and it shall be the residence of the Scholars forever. [2] There shall be a constant succession of scholars devoted to the study of letters, who shall be bound to employ themselves in the study of Arts or Philosophy, the Canons or Theology. Let there also be one member of the collegiate body, who shall be a grammarian, and must entirely devote himself to the study of grammar; let him have the care of the students in grammar, and to him also let the more advanced have recourse without a blush, when doubts arise in their faculty. [3] There is to be one person in every chamber, where Scholars are resident, of more mature age than the others, who is to make his report of their morals and advancement in learning to the Warden [4] The Scholars who are appointed to the duty of studying in the House are to have a common table, and a dress as nearly alike as possible.
