Anhalt-Bernburg
Anhalt-Bernburg was a principality of the Holy Roman Empire and a duchy of the German Confederation ruled by the House of Ascania with its residence at Bernburg in present-day Saxony-Anhalt. It emerged as a subdivision from the Principality of Anhalt from 1252 until 1468, when it fell to the Ascanian principality of Anhalt-Dessau.
