Durham University is a collegiate public research university in Durham, England, founded by an Act of Parliament in 1832 and incorporated by royal charter in 1837. It was the first recognised university to open in England for more than 600 years, after Oxford and Cambridge, and is thus the third-oldest university in England. As a collegiate university, its main functions are divided between the academic departments of the university and its 17 colleges. In general, the departments perform research and provide teaching to students, while the colleges are responsible for their domestic arrangements and welfare.

A collegiate university is a university in which functions are divided between a central administration and a number of constituent colleges. Historically, the first collegiate university was the University of Paris and its first college was the Collège des Dix-Huit. The two principal forms are residential college universities, where the central university is responsible for teaching and colleges may deliver some teaching but are primarily residential communities, and federal universities where the central university has an administrative role and the colleges may be residential but are primarily teaching institutions. The larger colleges or campuses of federal universities, such as University College London and University of California, Berkeley, may be effectively universities in their own right and often have their own student unions.
