The Presbyterian Church in Ireland, closely -but not formally - linked to the Church of Scotland in terms of theology and history, is the second-largest church and largest Protestant denomination. It is followed by the Anglican Church of Ireland, which was the state church of Ireland until it was disestablished by the Irish Church Act 1869.
