Prince-abbot A Prince-Abbot (German: "Fürstabt" ) is a title for a cleric who is a Prince of the Church (like a Prince-Bishop), in the sense of an "ex officio" temporal lord of a feudal entity, notably a State of the Holy Roman Empire. The secular territory ruled by the head of an abbey is known as Prince-Abbacy or Abbey-principality. The holder, however, does not hold the ecclesiastical office of a Bishop.
