Fulda
Fulda was an ecclesiastical principality of the Holy Roman Empire, centred on a Benedictine abbey on the Fulda. Its prince-abbot ruled the abbey's lands.
In 1356 Emperor Charles IV gave the prince-abbot the honorary title of Archchancellor of the Empress. Fulda became a prince-bishopric in 1752, but the monastery was dissolved in 1802 and its principality secularized in 1803 and joined to Orange-Nassau.
