Pre-Reformation , including the cathedral, the episcopal seat of the pre-Reformation archbishops. In 1118, the
metropolitan archbishoprics of
Armagh and Cashel were established at the
Synod of Ráth Breasail. The archbishop of Cashel had
metropolitan jurisdiction over the southern half of Ireland, known as
Leth Moga. At the
Synod of Kells in 1152, the metropolitan see of Cashel lost territory on the creation of the metropolitan archbishoprics of
Dublin and
Tuam. Under the
Church Temporalities (Ireland) Act 1833 (
3 & 4 Will. 4. c. 37), the
bishopric of Waterford and Lismore was united to the archbishopric of Cashel and Emly on 14 August 1833. On the death of Archbishop Laurence in 1838, the archepiscopal see lost its
metropolitan status and became the
bishopric of Cashel and Waterford in the
Church of Ireland Province of Dublin. Through reorganisation in the Church of Ireland in 1976, the bishopric of Emly was transferred to the
bishopric of Limerick and Killaloe; the remainder was united with other sees to become the
bishopric of Cashel and Ossory.
Catholic Church , the episcopal seat of the Catholic archbishops. In the Catholic Church, the archepiscopal see of Cashel had an unsettled history between the 1560s and the late 17th century. While some archbishops were appointed, there were periods when the see was vacant or administered by
vicars apostolic. From the 18th century onwards, a relaxation in the
Penal Laws permitted a consistent succession of archbishops. Since 10 May 1718, the archbishops of Cashel have also been
bishops of Emly when the two titles were united. On 22 November 2014,
Pope Francis accepted the resignation of the Most Reverend
Dermot Clifford from the
pastoral government of the
Metropolitan Archdiocese of Cashel and Emly, in accordance with
1983 Code of Canon Law on age grounds. On the same day, the Most Reverend
Kieran O'Reilly,
Bishop of Killaloe, was
appointed to be the next
Metropolitan Archbishop of Cashel and apostolic administrator of Emly. ==Pre-Reformation archbishops==
