In 1638, the senior Coburg-Eisenach line became extinct and its possessions were divided between the Altenburgs and the Weimars, this doubled the Saxe-Weimar possessions and made it again feasible to be divided. In c. 1640, the remaining brothers finally divided their patrimony, William remaining in Weimar, Albert (Albrecht) receiving seat as

and Gotha (1597–1638), the eldest son of Frederick William I. When Elisabeth Sophie's cousin Frederick William III, Duke of Altenburg, died unmarried 1672, the entire first Altenburg line became extinct in male line, opening a succession strife. Ultimately, Ernest and Elisabeth Sophie's sons received the lion's share of Altenburg inheritance, on basis of Duke John Philip's testament (as it was ultimately recognized that the Salic law does not prevent an agnate to will all his possessions to those other agnates of the house he desires to make his heirs, leaving other agnates without; and if those favored agnates also happened to be the testator's son-in-law and maternal grandsons, that is in no way prohibited), but a portion (one-fourth of the original Altenburg moiety) passed to the Saxe-Weimar branch. These two lines: Weimar and Gotha(-Altenburg) form the basis of future Ernestine lines, and both have surviving male lineage up to today. After the division of the inheritance of the first Altenburg line, the senior, Weimar, line held somewhat less than half of the Ernestine lands, and the junior, Gotha-Altenburg, line held more than half. Gotha-Altenburg line subdivided more and Weimar line not so much, and ultimately all the said Weimar line's possessions were concentrated in primogenitural hands in 1741 and in 1815 were raised to grand ducal title of Weimar.
Duke Ernest of Gotha and Duchess Elisabeth Sophie's numerous sons divided the inheritance (five-eighths of all Ernestine lands) initially to seven parts: Gotha-Altenburg, Coburg, Meiningen, Römhild, Eisenberg, Hildburghausen and Saalfeld. Of them, Coburg, Römhild and Eisenberg did not survive past that one generation and were apportioned between the four persevering lines.
The Ernestine territories in Thuringia were thus divided and recombined many times as Dukes left more than one son to inherit, and as various lines of the Ducal Ernestines died out in male line. Eventually,

Imperial Diet. In the
1792 session of the Imperial Diet, the Duke of Saxe-Weimar was also the Duke of Saxe-Eisenach, and had two votes (as well as three-eights of all the Ernestine lands); the Duke of Saxe-Altenburg was also the Duke of Saxe-Gotha (as senior heir of both Duke John Philip and Duke Ernest the Pious), and had two votes; and the Duke of Saxe-Coburg had one vote.
The other Ernestine duchies were never members of the Imperial Circle, and did not have the right to vote in the Imperial Diet as the five duchies that the other duchies did (for example, the principalities of Meiningen and Hildburghausen were such; that was one reason why Duke of Saxe-Hildburghausen exchanged his patrimony to that of Altenburg).
