Hamilton alleging that the colleges had unlawfully usurped the functions of the universities as the tutors had taken over the teaching from the professors. Royal Commissions in the 1850s led to Acts of Parliament in 1854 (for Oxford) and 1856 (for Cambridge) that, among other measures, limited the power of the colleges. Prior to these reforms, however, the first two new universities in England for over 600 years were established, both offering new versions of the collegiate university. The University of Durham was founded in 1832, taking Oxford for its model, and University College, Durham was created at the same time. This college, unlike those of Oxford and Cambridge, was not legally distinct from the university and nor was it responsible for teaching, which was carried out by university professors rather than college tutors. This restored the teaching role of the central university that had been lost at Oxford and Cambridge and the original role of the college as a residential rather than educational institution (c.f. Rashdall's comments on the Bologna colleges, above). It also pioneered the concept of residential colleges being owned by the university rather than being established as independent corporations, which provided a useful model for modern institutions looking to establish colleges. Unlike the earlier foundation of Trinity College Dublin, which had been established as "the mother of a university" but to which no other colleges had ever been added, the Durham system allowed for the university itself to found further colleges, which it did with the establishment of Hatfield College in 1846. The University of London, founded in 1836, was very different. It was, in its original form, an examining body for affiliated colleges. The first two of these - University College London (UCL; founded 1826) and King's College London (founded 1829) were already in existence and resembled non-collegiate 'unitary' universities, as found in Scotland and continental Europe, except in their lack of degree-awarding powers. There had been much dispute over UCL's attempt to gain recognition as a university, and the University of London was designed as a political solution to put an end to this dispute and to enable the students at both UCL and King's to receive degrees. It was modelled to a certain extent on Cambridge, where (at that time) the senate of the university was responsible for examinations and the colleges for the teaching, and also took on some features of the
