The '''bishop of Killala''' ({{Langx|ga|Easpag Chill Ala}}) is an [[Episcopal polity|episcopal]] title which takes its name after the village of [[Killala]] in [[County Mayo]], [[Republic of Ireland|Ireland]]. In the [[Roman Catholic Church]] it remains a separate title, but in the [[Church of Ireland]] it has been united with other bishoprics.
==History== The foundation of the [[Episcopal see]] of Killala dates to the time of [[Saint Patrick]] who had a church built there ([[St Patrick's Cathedral, Killala|Killala Cathedral]]), over which he placed one of his disciples, [[Muiredach of Killala|Saint Muredach]], as its first bishop.<ref>{{cite web |url=http://www.killalacathedral.killala.anglican.org/ |title=Welcome to the Cathedral Church of St Patrick, Killala |website=anglican.org |access-date=10 December 2014 |url-status=dead |archive-url=https://web.archive.org/web/20120404174822/http://www.killalacathedral.killala.anglican.org/ |archive-date=4 April 2012 }}</ref> Another of early bishop is believed to have been [[Cellach of Killala|Saint Cellach of Killala]].<ref>{{DNB|no-icon=1|prescript=|wstitle=Cellach}}</ref> The see was often called the bishopric of [[Uí Fiachrach Muaidhe]] or Tir Amalghaid ([[Tirawley]]) in the [[Irish annals]].<ref name=irishdioceseterritory>{{cite web | last = Walsh | first = Dennis |title=The Dioceses of Ireland: Territorial History |url=http://www.rootsweb.ancestry.com/~irlkik/ihm/diocese.htm |publisher=RootsWeb |access-date=2009-05-18}}</ref> Although the bishopric was founded in the 5th century, it wasn't until [[1111 in Ireland|AD 1111]] that the Diocese of Killala was established by the [[Synod of Ráth Breasail]].<ref name=irishdioceseterritory/> Its boundaries comprises the north-eastern portion of [[County Mayo]] and the [[Barony (Ireland)|barony]] of [[Tireragh]] in [[County Sligo]].<ref name=irishdioceseterritory/> After Bishop Ó Coineóil was restored in 1439, there were a number of rival candidates who were appointed but never took effect.<ref>{{Harvnb|Fryde|Greenway|Porter|Roy|1986}}, ''Handbook of British Chronology'', p. 359.</ref><ref>{{Harvnb|Moody|Martin|Byrne|1984}}, ''A New History of Ireland'', volume IX, pp. 329–330.</ref>
After the [[Reformation in Ireland|Reformation]], there were parallel [[apostolic succession]]s: one of the [[Church of Ireland]] and the other of the [[Roman Catholic Church]].
In the Church of Ireland, Killala continued as a separate title until 1622 when it was combined with [[Bishop of Achonry|Achonry]] to form the united [[Bishop of Killala and Achonry|bishopric of Killala and Achonry]].<ref>{{Harvnb|Fryde|Greenway|Porter|Roy|1986}}, ''Handbook of British Chronology'', p. 378.</ref> Under the [[Church Temporalities (Ireland) Act 1833]] ([[3 & 4 Will. 4]]. c. 37), the combined [[Episcopal see|sees]] of Killala and Achonry became part of the [[Archbishop of Tuam|archbishopric of Tuam]] in 1834. On the death of [[Power Le Poer Trench|Archbishop Le Poer Trench]] in 1839, the [[Ecclesiastical Province]] of Tuam lost its [[Metropolitan bishop|metropolitan status]] and became the united [[Bishop of Tuam, Killala and Achonry|bishopric of Tuam, Killala and Achonry]] in the [[Province of Armagh (Church of Ireland)|Ecclesiastical Province of Armagh]].<ref>{{Harvnb|Fryde|Greenway|Porter|Roy|1986}}, ''Handbook of British Chronology'', p. 407.</ref><ref>{{Harvnb|Moody|Martin|Byrne|1984}}, ''A New History of Ireland'', volume IX, p. 438.</ref>
