Jesus College is one of the constituent colleges of the University of Oxford in England. The college was founded in 1571 by Queen Elizabeth I at the request of Hugh Price, a Welsh clergyman, 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. Women have been admitted since 1974, when the college was one of the first five men's colleges to become co-educational. Old members of Jesus College are sometimes known as Jesubites. Three Archbishops of Wales have studied at Jesus College. A. G. Edwards, the first archbishop of the Church in Wales after its disestablishment, read Literae Humaniores from 1871 to 1874, and was archbishop from 1920 to 1934. Glyn Simon, a student from 1922 to 1926, was Archbishop of Wales from 1968 to 1971. He was succeeded by Gwilym Williams, who was archbishop from 1971 to 1982. Other bishops to have held office in Wales include Francis Davies, Roy Davies, John Harris and Morgan Owen (who were all Bishops of Llandaff), Humphrey Humphreys, Daniel Lewis Lloyd and Humphrey Lloyd (who were Bishops of Bangor), William Lloyd and John Wynne (who were Bishops of St Asaph), and John Owen and William Thomas (who were Bishops of St David's). William Havard was a Welsh rugby international before becoming Bishop of St Asaph, then Bishop of St David's.
