Princess Gisela Agnes of Anhalt-Köthen

Gisela Agnes was the only surviving child of Prince Leopold of Anhalt-Köthen (1694–1728) from his first marriage to Friederike Henriette (1702–1723), daughter of Prince Charles Frederick of Anhalt-Bernburg.

When her father died without leaving a male heir, he was succeeded as Prince of Anhalt-Köthen by her uncle Augustus Louis of Anhalt-Köthen. However, Gisela Agnes claimed her allodial title and took the case to the Reichskammergericht. Prince John Augustus of Anhalt-Zerbst mediated and a compromise was reached. Gisela was compensated with a sum of 100000taler plus and annual pension until her marriage. She also received her father's collection of guns and coins and another 32000taler for the estates of Prosigk, Klepzig and Köthen.

She married on 25 May 1737 in Bernburg her cousin, Prince Leopold II Maximilian of Anhalt-Dessau (1700–1751). The marriage was described as very happy. The death of his wife hit Leopold II so hard that he, already in delicate health, died only eight months later. She was buried in the St. Mary's Church in Dessau.
