The University of Oxford (informally "Oxford University" or "Oxford"), located in the English city of Oxford, is the oldest surviving university in the English-speaking world and is regarded as one of the world's leading academic institutions. Although the exact date of foundation remains unclear, there is evidence of teaching there as far back as the 11th century. 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" have many common features and are sometimes collectively and colloquially referred to as "Oxbridge". For more than a century, Oxford has served as the home of the Rhodes Scholarship, which brings students from a number of countries to study at Oxford as postgraduates. (more about the university...)
The colleges of the university, of which there are 38, are autonomous self-governing institutions. All students and teaching staff belong to one of the colleges, or to one of the six Permanent Private Halls (religious foundations that admit students to study at Oxford). The colleges provide tutorials and classes for students, while the university provides lectures and laboratories, and sets the degree examinations. Most colleges accept undergraduate and postgraduate students, although some are for graduate students only; All Souls does not have students, only Fellows, while Harris Manchester is for students over the age of 21. All the colleges now admit both men and women: the last single-sex college, St Hilda's, began to admit men in 2008. The oldest colleges are University, Balliol, and Merton, established between 1249 and 1264, although there is dispute over when each began teaching. The most recent new foundation is Kellogg College, founded in 1990, while the most recent overall is Green Templeton College, formed in 2008 as the result of a merger of two existing colleges.
