Osnabruck
A city in northwestern Germany, and the seat of a Bishop from 783. In the 16th century the Bishopric and surrounding territory was converted to Protestantism, in which it remained until being recaptured by Catholic forces, then retaken by the Protestants during the 30 Years War. The treaty ending that conflict contained the unusual provision that Catholic and Protestant Bishops should alternate thereafter. Another note of interest concerns the last Bishop. When the Bishopric was mediatized in 1802, its Princely status was retained as an appanage of Hannover. The Elector (and later King) at the time was the last Bishops father, thus providing the only example I can think of off-hand of a father succeeding his son.
