House of Henneberg - Disestablishment

Disestablishment

Whereas the male line of the House of Babenberg became extinct in 1246, the Counts of Henneberg lived on until 1583. In 1554 William IV of Henneberg-Schleusingen had signed a treaty of inheritance with Duke John Frederick II of Saxony. However, when the last Count George Ernest of Henneberg died, both the Ernestine and the Albertine branch of the Wettin dynasty claimed his estates, that were finally divided in 1660 among the Ernestine duchies of Saxe-Weimar and Saxe-Gotha and the Albertine duke Maurice of Saxe-Zeitz. The Lordship of Schmalkalden fell to Landgrave William IV of Hesse-Kassel according to a 1360 inheritance treaty.

After the 1815 Congress of Vienna the former Albertine parts around Schleusingen and Suhl fell to the Prussian province of Saxony. King Frederick William III of Prussia assumed the title of a Princely Count of Henneberg, which his successors from the House of Hohenzollern bear ever since.
