University of Cambridge established only for women. Darwin College, the first wholly graduate college of the university, matriculated both men and women students from its inception in 1964 – and elected a mixed fellowship. Of the undergraduate colleges, starting with Churchill, Clare and King's Colleges, the former men's colleges began to admit women between 1972 and 1988. One of the female-only colleges, Girton, also began to admit male students from 1979, but the other female-only colleges did not do likewise. As a result of St Hilda's College, Oxford, ending its ban on male students in 2008, Cambridge is now the only remaining United
University of Cambridge gave graduates from Cambridge the right to teach "everywhere in Christendom". After Cambridge was described as a "studium generale" in a letter by Pope Nicholas IV in 1290, and confirmed as such in a bull by Pope John XXII in 1318, it became common for researchers from other European medieval universities to visit Cambridge to study or to give lecture courses. The colleges at the University of Cambridge were originally an incidental feature of the system. No college is as old as the university itself. The colleges were endowed fellowships of scholars. There were also institutions without endowments, called hostels.
