Sigismund II, Prince of Anhalt-Dessau
After the death of his father in 1405, Sigismund inherited the principality of Anhalt-Dessau with his older brothers Waldemar IV and George I and his younger brother Albert V as co-rulers. By virtue of the family of law of the House of Ascania, there was no division of territories among them.
Sigismund married Matilda (died 1443), daughter of Bernhard VI, Prince of Anhalt-Bernburg. Both spouses were direct descendants of Henry I, Count of Anhalt, through his sons Bernhard I (ancestor of Matilda), and Siegfried I (ancestor of Sigismund). The marriage was childless.
Without direct heirs at the time of his death, Sigismund was succeeded by his surviving brothers and co-rulers.
