The second Archbishop was Lorcán Ua Tuathail (Saint Laurence O'Toole), previously Abbot of Glendalough, who had previously been elected as Bishop of Glendalough but had declined that office. During his time in office, religious orders from the continent came to Ireland, and as part of this trend, Laurence installed a community of canons to minister according to the Aroasian Rule in the Cathedral of the Holy Trinity, later known as Christ Church Cathedral, Dublin. Not only was the Irish Church transformed in that 12th century by new organisation and new arrivals from abroad, but Ireland's political scene was changed permanently by the coming of the Normans and the influence of the English Crown from 1171. Saint Laurence's successor was a Norman, and from then onward to the time of the Reformation, Dublin's Archbishops were all either Norman or English. High offices in the Church were never free of political influence, and in fact many of Dublin's Archbishops exercised civil authority for the English crown. Archbishop Henry of London's name appears in the text of "Magna Carta" along with the names of English Bishops as witnesses. In 1185, the Pope had granted a petition to combine the Dioceses of Dublin and Glendalough, to take effect on the death of the then Bishop of Glendalough. The union took effect in 1216, with the approval of Innocent III, and the dioceses have remained merged ever since. Archbishop de Leche of Dublin received a Papal Bull from Clement V in 1311, authorising him to establish the Medieval University of Dublin, and this process was completed in 1320, when the university statutes were confirmed by Pope John XXII to the next Archbishop, Alexander de Bicknor. The statutes mention the Chapters of both St. Patrick's and Christ Church Cathedrals, which are granted the power to confer degrees, and the aim appears to have been to provide lectures at the former. The then Dean of St. Patrick's, William de Rodyard, was elected first Chancellor of the University, and in 1358, King Edward III issued letters patent conferring protection on the students. In 1364, a Divinity Lecture was endowed, and in 1496, the Diocesan Synod granted stipends for the lecturers of the university. It has been said that the University never properly got started; certainly it languished, due to the lack of sufficient endowments.
