After the death of the childless Henry in 1710, his domains were divided between the four duchies – Saxe-Gotha-Altenburg, Saxe-Coburg-Saalfeld, Saxe-Meiningen and Saxe-Hildburghausen. Saxe-Gotha-Altenburg took seven-twelfths of the District of Themar. Saxe-Coburg-Saalfeld had five-twelfths of the District of Themar and one-third of the District of Römhild. Two-thirds of the District of Römhild went to Saxe-Meiningen. Saxe-Hildburghausen got the rest – the winery of Behrungen, the estate of Milz and the Echter properties.
With the rearrangement of the Ernestine duchess in 1826, all the territories of the former Duchy of Saxe-Römhild were concentrated in only one duchy – Saxe-Melningen.
