Fulda
From its foundation, the abbey Fulda and its territory was subject only to the German emperor, not to the control of the local lords. Fulda was made a bishopric in 1752 and the prince-abbots were given the additional title of prince-bishop. The prince-abbots (and later prince-bishops) ruled Fulda and the surrounding region until the bishopric was forcibly dissolved by Napoleon in 1802.
