In page Ansbach:

"

The counts of Öttingen ruled over Ansbach until the Hohenzollern burgrave of Nürnberg took over in 1331. The Hohenzollerns made Ansbach the seat of their dynasty until their acquisition of the Margraviate of Brandenburg in 1415. After the 1440 death of Frederick I, a cadet branch of the family established itself as the margraves of Ansbach. George the Pious introduced the Protestant Reformation to Ansbach in 1528, leading to Gumbertus Abbey's secularization in 1563.[citation needed]
