Archdiocese of Tuam (Church of Ireland)
former archdiocese that lasted until 1839

The Archbishopric of Tuam existed from the mid twelfth century until 1839, with its seat at Tuam.
St Jarlath (c. 445–540) is considered to have founded Tuam as the seat of a bishop in about 501, and he stands first in the list of bishops of Tuam. However, the names of only two other bishops are recorded before the eleventh century, Ferdomnach (died 781) and Eugene mac Clerig (died 969).
Tuam achieved a new importance after it became the seat of the O'Connor High Kings of Ireland in the early 11th century. The O'Connors had previously been based at Cruachain, County Roscommon. The first St Mary's Cathedral on the present site was begun in the 12th century, when Turlough O'Connor (1088–1156) was High King. This marked Tuam's becoming the seat of an archbishop, following the Synod of Kells of 1152.
With the Reformation, the new Church of Ireland established its own archdiocese, which was separate from the authority of the Pope. This archdiocese became the central part of the new Province of Tuam, an ecclesiastical province of the Church of Ireland, so continuing until the nineteenth century.
