Oxford University. Legend has it that Oxford University was founded by King Alfred in 872. A more likely scenario is that it grew out of efforts begun by Alfred to encourage education and establish schools throughout his territory. There may have been a grammar school there in the 9th century. A grammar school was exactly what it sounds like; a place for teaching Latin grammar. The University as we know it actually began in the 12th century as gatherings of students around popular masters. The university consisted of people, not buildings. The buildings came later as a recognition of something that already existed. In a way, Oxford was never founded; it grew.
Cambridge University was founded by students fleeing from Oxford after one of the many episodes of violence between the university and the town of Oxford.
Students. University students chose their own course of studies, hired their own professors, and picked their own hours of study. They were free to leave one professor if they tired of him, and join another, attending several lectures before deciding whether to pay him or not. The only books were the professors, and students wrote notes on parchment or, more commonly, on wax tablets.
