 For example, regions, that used to be under the care of the bishoprics of Bamberg, Würzburg and Eichstätt, are mainly Catholic today.On the other hand, all former territories of the imperial cities and the margraviates of Ansbach and Bayreuth have remained mainly Lutheran.The region around the city of Erlangen, which belonged to the Margraviate of Bayreuth, was a refuge for the Huguenots who fled there after the St. Bartholomew's Day massacre in France.
