William Louis, Prince of Anhalt-Köthen


William Louis of Anhalt-Köthen, was a German prince of the House of Ascania and ruler of the principality of Anhalt-Köthen.
He was the second son of Louis I, Prince of Anhalt-Köthen, but second-born son of his second wife Sophie, daughter of Simon VI, Count of Lippe.

Life

William Louis was only twelve years of age when he succeeded his father in Köthen in 1650. During his minor years, his uncle Prince Augustus of Anhalt-Plötzkau acted as regent. After the death of Augustus in 1653, his sons Lebrecht and Emmanuel took over the regency until William was formally proclaimed of age in 1659.
In Köthen on 25 August 1663 William Louis married Elisabeth Charlotte, daughter of his cousin Frederick, Prince of Anhalt-Harzgerode, and granddaughter of Christian I, Prince of Anhalt-Bernburg. The union was childless.
On his death without issue, the line of Anhalt-Köthen became extinct. His principality was inherited by his cousins and former regents, Lebrecht and Emmanuel of Anhalt-Plötzkau, who took the name of Anhalt-Köthen as the principal title of their family. Their former principality of Plötzkau was given to Victor Amadeus of the principality of Anhalt-Bernburg, from which it was originally extracted.
