Historical Trajectory
Phase I: Rise
Anhalt-Köthen was first established in 1396 when the Principality of Anhalt-Zerbst was partitioned, creating separate lines at Dessau and Köthen. Ruled by the House of Ascania, it existed as a small territorial entity within the Holy Roman Empire. This first incarnation lasted until 1562, when Prince Joachim Ernest of Anhalt-Zerbst absorbed it into a reunited Principality of Anhalt, extinguishing the initial Köthen line.
Phase II: Zenith
The principality's most distinguished period followed its recreation in 1603. Under Leopold, Prince of Anhalt-Köthen, the court gained cultural prominence when Johann Sebastian Bach served as court Kapellmeister from 1717 to 1723, composing major instrumental works including the Brandenburg Concertos. In 1806, Napoleon's reorganization of German territories prompted an elevation of Anhalt-Köthen to the rank of duchy.
Phase III: Decline
The Anhalt-Köthen line gradually weakened through the nineteenth century, and when Duke Henry died on 23 November 1847, the ruling branch became extinct. After a period of administration, a patent of 22 May 1853 formally united Anhalt-Köthen's territories with Anhalt-Dessau. The merged state eventually consolidated further into the Duchy of Anhalt in 1863, ending Köthen's separate political identity.
