When in 1638 the Ernestine Saxe-Eisenach and Saxe-Coburg branch became extinct upon the death of Duke John Ernest, Wilhelm of Saxe-Weimar inherited large parts of his estates. In 1640 however he had to involve his younger brothers Ernest I and Albert IV , thereby (re-)establishing the Duchies of Saxe-Gotha and short-lived Saxe-Eisenach , which was again dissolved upon Duke Albert's death in 1644.
When Emperor Frederick Barbarossa deposed the Saxon duke, Henry the Lion in 1180, the Wittenberg lands belonged to Albert's youngest son, Count Bernhard of Anhalt, who assumed the Saxon ducal title. Bernard's eldest son, Albert I , ceded the territory known as Anhalt to his younger brother, Henry , retaining the ducal title and attached to this territory the lordship of Lauenburg .
