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. 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. 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.
The university is made up of 39 constituent colleges, and a range of academic departments, which are organised into four divisions. All the colleges are self-governing institutions within the university, each controlling its own membership and with its own internal structure and activities. It does not have a main campus, and its buildings and facilities are scattered throughout the city centre. Undergraduate teaching at Oxford is organised around weekly tutorials at the colleges and halls, supported by classes, lectures, seminars, and laboratory work provided by university faculties and departments; some postgraduate teaching includes tutorials organised by faculties and departments. It operates the world's oldest university museum, as well as the largest university press in the world and the largest academic library system nationwide. In the fiscal year ending 31 July 2018, the university had a total income of £2.237 billion, of which £579.1 million was from research grants and contracts. The university is quoted as among the best higher learning institutions by most international and major national league tables.
Oxford has educated many notable alumni, including 27 prime ministers of the United Kingdom and many heads of state and government around the world. As of 2019, 69 Nobel Prize winners, 3 Fields Medalists, and 6 Turing Award winners have studied, worked, or held visiting fellowships at the University of Oxford, while its alumni have won 160 Olympic medals. Oxford is the home of numerous scholarships, including the Rhodes Scholarship, which is one of the oldest international graduate scholarship programmes.
