Anhalt-Harzgerode
Anhalt-Harzgerode was a principality and member of the Holy Roman Empire. It was created in 1635 following the partition of Anhalt-Bernburg with Frederick, a younger son of Christian I becoming the reigning prince. The death of Prince Frederick's son William Louis in 1709 resulted in the extinction of the ruling family and Anhalt-Harzgerode was reunited with Anhalt-Bernburg.
