Prince-Bishopric of Liège
The Prince-Bishopric of Liège or Principality of Liège was an ecclesiastical principality of the Holy Roman Empire situated for the most part in present-day Belgium. It was an Imperial Estate, so the bishop of Liège, as its prince, had a seat and a vote in the Imperial Diet. The Prince-Bishopric of Liège should not be confused with the Diocese of Liège, which was larger and over which the prince-bishop exercised only the usual responsibilities of a bishop.
