Jesus College is one of the constituent colleges of the University of Oxford in England. Its alumni include politicians, lawyers, bishops, poets, and academics. Some went on to become fellows of the college; 14 students later became principal of the college. It was founded in 1571 by Queen Elizabeth I, at the request of a Welsh clergyman, Hugh Price, who was Treasurer of St David's Cathedral in Pembrokeshire. The college still has strong links with Wales, and about 15% of students are Welsh. There are 340 undergraduates and 190 students carrying out postgraduate studies. Old members of Jesus College are sometimes known as Jesubites. From the world of politics, the college's alumni include two Prime Ministers (Harold Wilson of Britain and Norman Manley of Jamaica), one Speaker of the House of Commons (Sir William Williams), a co-founder of Plaid Cymru (D. J. Williams) and a co-founder of the African National Congress (Pixley ka Isaka Seme). Members of Parliament from the three main political parties in the United Kingdom have attended the college, as have politicians from Australia (Neal Blewett), New Zealand (Harold Rushworth), Sri Lanka (Lalith Athulathmudali) and the United States (Heather Wilson). The list of lawyers include one Lord Chancellor (Lord Sankey) and one Law Lord (Lord du Parcq). The list of clergy includes three Archbishops of Wales (A. G. Edwards, Glyn Simon and Gwilym Williams). Celticists associated with the college include Sir John Morris-Jones, Sir Thomas (T. H.) Parry-Williams and William John Gruffydd, whilst the list of historians includes the college's first graduate, David Powel, who published the first printed history of Wales in 1584, and the Victorian historian John Richard Green.
