Louis Augustus, Duke of Anhalt-Köthen
Prince Louis Augustus was born posthumously, four days after the death of his father, on 16 September 1802.One year later, his uncle, the reigning Prince (and later Duke) Augustus Christian Frederick of Anhalt-Köthen divorced his wife after eleven years of childless union, and showed no interest in marrying again; this left Louis Augustus as his uncle's heir presumptive.Duke Leopold III of Anhalt-Dessau, as head of the whole House of Anhalt, assumed the regency on his behalf until his death in 1817, when his grandson and heir, Leopold IV, assumed guardianship of the duke.Louis Augustus died at only sixteen years of age and because he was still a minor, he never ruled on his own.With him, the main line of Anhalt-Köthen became extinct, and he was succeeded by his uncle Frederick Ferdinand, a member of the Anhalt-Köthen-Pless branch.
