 The Order of St Patrick initially had thirteen officers: the Prelate, the Chancellor, the Registrar, the Usher, the Secretary, the Genealogist, the King of Arms, two heralds and four pursuivants. Many of these offices were held by clergymen of the Church of Ireland, the then-established church. After the disestablishment of the Church in 1871, the ecclesiastics were allowed to remain in office until their deaths, when the offices were either abolished or reassigned to lay officials. All offices except that of Registrar and King of Arms are now vacant.
