The Anglican Archbishop of Armagh is the ecclesiastical head of the Church of Ireland, the metropolitan of the Province of Armagh and the diocesan bishop of the Diocese of Armagh. Like his counterpart the Roman Catholic Archbishop of Armagh, he bears the title Primate of All Ireland.
The diocese traces its history to Saint Patrick in the 5th century, who founded the See, and his current successor is the Most Reverend Richard Clarke, who was enthroned at St Patrick's Church of Ireland Cathedral in Armagh on 15 December 2012.
Saint Patrick, having received some grants of land from the chieftain Daire, on the hill called Ard-Macha (the Height of Macha), built a stone church on the summit and a monastery and some other religious edifices round about, and fixed on this place for his metropolitan see. In Irish times, the primacy of Armagh was questioned only by the great southern centre of the Irish Church, at Cashel. Brian Boru recognized the supremacy of Armagh, possibly in a political move to gain support from Armagh for Boru's claim to the High Kingship. Another noteworthy incumbent was St. Malachy O'Morgair (1134–37), who suffered many tribulations in trying to effect a reformation in the diocese. St. Malachy is honoured as the patron saint of the diocese. When the English kings got a footing in the country, they began to intervene in the election of bishops. The English kings also began to claim possession of the temporalities of the sees during vacancies and to insist on the newly elected bishops suing them humbly for their restitution.
