Table History Elector Ernest died in 1486, and was succeeded by his son,
Frederick the Wise. Leipzig, the economic center of Saxony, as well as the seat of the only university in Saxony, was located in Albertine Saxony. Wanting a university in his lands, for example, to educate civil servants and pastors, Frederick founded the University of Wittenberg in 1502. It was there that
Martin Luther posted his 95 Theses. Frederick protected Luther, refusing to extradite him to
Rome for trial. Frederick, like other German princes, allowed Lutheran reforms to be implemented in his domain. Frederick III died in 1525; he was succeeded by his brother,
John the Steadfast (1525–1532). John was a leader in the
Schmalkaldic League of
Protestant princes in the
Holy Roman Empire. John died in 1532 and was succeeded by his son
John Frederick I. For the first ten years of his reign, John Frederick shared the rule of Ernestine Saxony with his stepbrother,
John Ernest, titularly Duke of
Saxe-Coburg, who died childless. John Frederick increasingly hardened his support of the Lutheran Reformation, while the Emperor,
Charles V, avoided direct confrontation with the Protestant princes, as he needed their support in his struggle with
France. Charles eventually came to terms with France, and turned his attention to the Protestant lands of the Holy Roman Empire. In 1546 the Schmalkaldic League raised an army. Elector John Frederick led the league's troops south, but shortly thereafter John Frederick's cousin,
Duke Maurice of Albertine Saxony (Meissen), invaded Ernestine Saxony. John Frederick hurried back to Saxony, expelled Maurice from the Ernestine lands, conquered Albertine Saxony and proceeded to invade Bohemia (held directly by Emperor Charles V's brother Ferdinand and that latter's wife
Anna of Bohemia and Hungary). Charles' forces drove the Schmalkaldic League troops back and decisively defeated them in the
Battle of Mühlberg (1547). John Frederick was wounded and taken prisoner. The Emperor condemned him to death as a rebel, but stayed the execution because he did not want to take the time to capture Wittenberg, defended by John Frederick's wife
Sybille of Cleves. To save his life, John Frederick conceded in the
Capitulation of Wittenberg to resign the Electorate and the government of his country in favor of Maurice of the Albertine Saxony, and his punishment was changed into imprisonment for life. When the newly minted Elector Maurice, having again changed sides, attacked the Emperor, Duke John Frederick was released from prison, and given back the Landgraviate of Thuringia. He established his capital in
Weimar, and started a university at
Jena (to replace the one in Wittenberg lost to Maurice) before his death in 1554. The three sons of John Frederick I shared the territory, with John Frederick II becoming head (and briefly, 1554–1556, holding the electoral title) with his seats in Eisenach and Coburg, the middle brother John William staying in Weimar (
Saxe-Weimar), and the youngest, John Frederick III (namesake of the eldest brother, which has caused much confusion in history writing) establishing residence in Gotha (
Saxe-Gotha). When John Frederick III of Gotha died unmarried and heirless in 1565, John William of Weimar tried to claim succession to Saxe-Gotha, but the sons of the imprisoned John Frederick II entered their own claim. The contenders reached agreement in 1572 in the
Division of Erfurt by which John William added the districts of
Altenburg,
Gotha and
Meiningen to Saxe-Weimar. When John William died a year later, his older son, Frederick William I received Altenburg, Gotha and Meiningen with the title of Duke of
Saxe-Altenburg, and with his several sons founding the first Saxe-Altenburg line, while
Saxe-Weimar went to the younger son John II.
John Casimir (died heirless 1633), the older son of John Frederick II, and
John Ernest (died heirless 1638), the younger son of John Frederick II, received together the territory of
Saxe-Coburg-Eisenach, but were appointed a legal guardian because they were minors. In 1596 the brothers agreed to split the duchy into
Saxe-Coburg and
Saxe-Eisenach.
Johann II, Duke of Saxe-Weimar (or John II), died young leaving eight surviving sons (including
Bernhard of Saxe-Weimar, the youngest, the famed general) and a will ordering them to rule jointly. When the eldest of them,
John Ernest I, Duke of Saxe-Weimar died in action (1626) unmarried, two more of his brothers were already deceased without children, leaving five dukes of Saxe-Weimar, with
Wilhelm the eldest. Two more died within fifteen years, including Bernhard in 1639, without heirs. 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 , the remaining brothers finally divided their patrimony, William remaining in Weimar, Albert (Albrecht) receiving seat as Duke of Eisenach and Ernest (by-named "the Pious") also got his share and became known as
Duke of Gotha.
Ernest I, Duke of Saxe-Gotha (1601–1675) had married Elisabeth Sophie, the only child of
Johann Philipp, Duke of Saxe-Altenburg 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,
primogeniture became the rule for inheritance in the Ernestine duchies, but not before the number of Ernestine duchies had risen to ten at one point. By 1826 the remaining Ernestine duchies were the Grand Duchy of
Saxe-Weimar-Eisenach (approximately three-eighths of all the Ernestine lands), and the ("Elisabeth-Sophie-line") duchies of
Saxe-Gotha-Altenburg,
Saxe-Meiningen,
Saxe-Hildburghausen and
Saxe-Coburg-Saalfeld. In 1826,
Ernest the Pious' senior line of Gotha-Altenburg became extinct. The daughter of its penultimate duke had been married with the Duke of Coburg and Saalfeld, and the couple had two sons – the younger of whom was to become
Albert, Prince Consort of the United Kingdom. The patrimony of Gotha-Altenburg was divided between the other three lines stemming from Ernest the Pious and Elisabeth Sophie, causing changes in nomenclature: onwards, they were
Saxe-Meiningen-Hildburghausen,
Saxe-Altenburg (the former Hildburghausen line) and
Saxe-Coburg and Gotha – the youngest line (originally Saalfeld line) receiving the "maternal" seat of Gotha which had been the seat of Ernest the Pious, progenitor of all these seven lines. All of the Ernestine duchies ended with the abolition of the monarchy and princely states in Germany shortly after the end of
World War I. Five of the Ernestine duchies were members of the
Upper Saxon Circle of the Holy Roman Empire: • Saxe-Weimar • Saxe-Eisenach • Saxe-Coburg • Saxe-Gotha • Saxe-Altenburg Membership in the Circle gave the ruler of a state a vote in the
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). However they were all autonomous and ultimately, with the dissolution of the
Holy Roman Empire on 6 August 1806, that issue became irrelevant. •
