On March 26, 1675, Ernst I, Duke of Saxe-Gotha-Altenburg died. Initially, his sons governed the Duchy of Saxe-Gotha-Altenburg, as set out in their father’s will. On February 24, 1680, the seven brothers concluded a treaty of separation, with each brother getting a portion of the Duchy of Saxe-Gotha Altenburg and becoming a Duke.
- Friedrich I became Duke of Saxe-Gotha-Altenburg
- Albrecht became Duke of Saxe-Coburg
- Bernhard I became Duke of Saxe-Meiningen
- Heinrich became Duke of Saxe-Römhild
- Christian became Duke of Saxe-Eisenberg
- Ernst became Duke of Saxe-Hildburghausen
- Johann Ernst IV became Duke of Saxe-Saalfeld
Albrecht of Saxe-Coburg and Heinrich of Saxe-Römhild died without male heirs. Upon their deaths, Johann Ernest took possession of Coburg (in 1699) and Römhild (in 1714). In 1699, Johann Ernst became Duke of Saxe-Coburg-Saalfeld.
In 1825, 145 years after the initial split, the House of Saxe-Gotha-Altenburg became extinct and the Duchy of Saxe-Gotha-Altenburg was split. Saxe-Gotha passed to the Duke of Saxe-Coburg-Saalfeld who in turn gave Saalfeld to the Duke of Saxe-Meiningen. The Duke of Saxe-Hildburghausen received Saxe-Altenburg and gave the district of Hildburghausen to Saxe-Meiningen.
As a result:
- Ernst III, Duke of Saxe-Coburg-Saalfeld became Ernst I, Duke of Saxe-Coburg and Gotha. Ernst I had two sons: his heir, the future Ernst II, Duke of Saxe-Coburg and Gotha and Prince Albert of Saxe-Coburg and Gotha, the husband of Queen Victoria.
- The Duchy of Saxe-Hildburghausen ceased to exist. Friedrich, Duke of Saxe-Hildburghausen became Friedrich, Duke of Saxe-Altenburg.
- Bernhard II, Duke of Saxe-Meinigen remained Duke of Saxe-Meiningen but had the additional land that encompassed Hildburghausen and also Saalfeld.
- The Duchies of Saxe-Coburg and Gotha, Saxe-Altenburg, and Saxe-Meiningen continued to remain the same until the abolition of the German monarchies after World War I.
The territory that encompassed the Duchy of Saxe-Coburg and Gotha in now in the German states of Bavaria and Thuringia.
