The University of Oxford is a collegiate research university in Oxford, England. There is evidence of teaching as early as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation after the University of Bologna. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris.[2] After disputes between students and Oxford townsfolk in 1209, some academics fled north-east to Cambridge where they established what became the University of Cambridge.[12] The two 'ancient universities' are frequently jointly called 'Oxbridge'. The history and influence of the University of Oxford has made it one of the most prestigious universities in the world.
