History of reform of the House of Lords
Though the religion of a minority of Irish people at the time, the Church of Ireland remained the official, established religion of Ireland, until its disestablishment by the Irish Church Act 1869 came into effect in 1871. The representation of the Church in the House of Lords also ceased.
