There was an independent principality called Anhalt-Bernburg following the subdivision of the principality of Anhalt in 1603. This mini state was elevated to the rank of a duchy in 1806, and merged once more with the other parts to form a united duchy of Anhalt again in 1863.
The arms display a bear walking on a red wall. The bear is the heraldic animal of Bernburg and Anhalt. The arms are similar to the old arms of the medieval state of Anhalt-Bernburg and the province of Anhalt within the Weimar Republic.
