The
diocese of Dublin was formally established by
Sigtrygg (Sitric) Silkbeard,
King of Dublin in 1028, and the first bishop,
Dúnán, was consecrated in about the same year. The diocese of Dublin was subject to the
Province of Canterbury until 1152. At the
Synod of Kells, held in March 1152, Dublin was raised to an
ecclesiastical province with the archbishop of Dublin having the jurisdiction over the bishops of
Ferns,
Glendalough,
Kildare,
Leighlin and
Ossory. In 1214, the dioceses of Dublin and Glendalough were united, which was confirmed by
Pope Innocent III on 25 February 1216 and by
Pope Honorius III on 6 October 1216. After the
Reformation, there are
apostolic successions of Church of Ireland and Roman Catholic archbishops.
In the Church of Ireland From 1846 to 1977, the Church of Ireland diocese of Dublin and Glendalough was united with the see of
Kildare. The current
Church of Ireland archbishop is
Michael Jackson, Archbishop of the
Diocese of Dublin and Glendalough.
In the Catholic Church Sometime after the Reformation, Glendalough was dropped from the Catholic archdiocese title. The current
Catholic archbishop is
Dermot Farrell, Archbishop of the
Archdiocese of Dublin, who was appointed to the title on 29 December 2020 and installed at
St Mary's Cathedral, Dublin on 2 February 2021. ==Pre-Reformation bishops and archbishops==
