The Division of Chemnitz settled the succession in the Landgraviate of Thuringia.
After the death of Frederick the Severe, Margrave of Meissen and Landgrave of Thuringia, the five heirs of the House of Wettin decided to divide the country. On 13 November 1382 they met in Chemnitz (probably at the local Benedictine monastery) and divided the land among themselves as follows:
First Part - Balthasar, brother of the deceased, received much of the Landgraviate of Thuringia: Wartburg, Eisenach, Creuzburg, Markgrafenstein, Salzungen, Lichtenberg, Tenneberg, Gotha, Wachsenburg Castle, Mehlis, Elgersburg, Schwarzwald, Liebenstein, Ballhausen, Grüningen, Weißensee, Tennstedt, Herbsleben, Salza, Thamsbrück, Bischofsgottern, Weimar, Eckartsberga, Finne, Neumark, Buttelstedt, the area around Erfurt, the bailiwick of Nordhausen, Wiehe, Schönwerda, Buttstädt, Sangerhausen, Grillenburg, Brandenberg, Großfurra, Brücken, Bendeleben, Rothenburg, Kyffhausen, Schlotheim, Treffurt, Breitenbach, the forest of Gerstungen, Beyernaumburg, Gebesee and Sittichenbach Abbey.
Second Part - William I the one-eyed, brother of the deceased, received the Margraviate of Meissen.
Third Part - Frederick I, the Belligerent, William II, the Rich and George, sons of the deceased (all three until 1390 under guardianship of their mother Catherine of Henneberg), received the Osterland, Landsberg, Pleissnerland, Orlamünde, Kahla, Jena and Naumburg.
Freiberg was to be ruled jointly.
After the death of William I the one-eyed in 1407 the Margraviate of Meissen was inherited by his nephews Frederick I the Belligerent and William II the Rich.
Frederick I, the Belligerent or the Warlike, a member of the House of Wettin, ruled as Margrave of Meissen from 1407 and Elector of Saxony from 1423 until his death.
Frederick III, the Strict, Landgrave of Thuringia and Margrave of Meissen, was the son of Frederick II, Margrave of Meissen and Mathilde of Bavaria.
Frederick II was the margrave of Meissen from 1323 until his death.
Frederick I, called the Brave or the Bitten was Margrave of Meissen and Landgrave of Thuringia.
Albert II, the Degenerate was a Margrave of Meissen, Landgrave of Thuringia and Count Palatine of Saxony. He was a member of the House of Wettin.
Henry III, called Henry the Illustrious from the House of Wettin was Margrave of Meissen and last Margrave of Lusatia from 1221 until his death; from 1242 also Landgrave of Thuringia.
The Margravate or Margraviate of Meissen was a medieval principality in the area of the modern German state of Saxony. It originally was a frontier march of the Holy Roman Empire, created out of the vast Marca Geronis in 965. Under the rule of the Wettin dynasty, the margravate finally merged with the former Duchy of Saxe-Wittenberg into the Saxon Electorate by 1423.
The Ernestine duchies, also known as the Saxon duchies, were a group of small states whose number varied, which were largely located in the present-day German state of Thuringia and governed by dukes of the Ernestine line of the House of Wettin.
Theodoric I, called the Oppressed, was the Margrave of Meissen from 1198 until his death. He was the second son of Otto II, Margrave of Meissen and Hedwig of Brandenburg.
The Treaty of Leipzig or Partition of Leipzig was signed on 11 November 1485 between Elector Ernest of Saxony and his younger brother Albert III, the sons of Elector Frederick II of Saxony from the House of Wettin. The agreement perpetuated the division of the Wettin lands into a Saxon and a Thuringian part, which in the long run obstructed the further development of a Central German hegemonic power in favour of Brandenburg-Prussia.
The Division of Altenburg was the plan for the division of the Meissen lands agreed upon by the two hostile Wettin brothers Elector Frederick II of Saxony and William III on 16 July 1445 at Altenburg. The brothers had attempted to reconcile, but eventually the division led the Saxon Fratricidal War, which began in 1446 and lasted for five years, until the Peace of Naumburg was negotiated in 1451. Following the peace, the subsequent Treaty of Eger in 1459, and the deaths of Frederick II and William III, the two sons of Frederick II eventually gained control of the land of both their father and William III.
The Saxon Fratricidal War was a war fought between the two brothers Frederick II, Elector of Saxony and Duke William III over Wettin ruled areas from 1446 to 1451. After a dispute over the division of certain family lands between Frederick II and William III, the Division of Altenburg eventually led to growing tensions between the two brothers and an inability to agree on who ruled which areas. After failed attempts at reconciliation, the war broke out and lasted for five years. The war was destructive and had no clear winner before being ended with a peace treaty at Naumburg. Following the war and subsequent divisions the Saxons lost much of their former power and influence within the different German states and families.
The Treaty of Eger, also called Main Compromise of Eger or Peace of Eger was concluded on 25 April 1459 in the Imperial City of Eger (Cheb), administrative seat of the immediate pawn of Egerland. The treaty established the border between the Kingdom of Bohemia and the Electorate of Saxony on the main ridge of the Ore Mountains stretching from Eger to the River Elbe. The border remains largely unchanged up to today, separating the Czech Republic and Germany, and is thus one of the oldest still extant borders in Europe.
The Duchy of Thuringia was an eastern frontier march of the Merovingian kingdom of Austrasia, established about 631 by King Dagobert I after his troops had been defeated by the forces of the Slavic confederation of Samo at the Battle of Wogastisburg. It was recreated in the Carolingian Empire and its dukes were appointed by the king until it was absorbed by the Saxon dukes in 908. From about 1111/12 the territory was ruled by the Landgraves of Thuringia as Princes of the Holy Roman Empire. When Frederick IV, the last independent ruler of Thuringia died in 1440, the territory passed to his nephew, the Saxon elector Frederick II.
Wilhelm II, the Rich was the second son of Margrave Frederick the Strict of Meissen and Catherine of Henneberg.
William I, the One-Eyed was Margrave of Meissen. His nickname is related to the legend that Saint Benno appeared to him because of his disputes with the Church in a dream and he had an eye gouged out.
Landgrave Balthasar of Thuringia was Margrave of Meissen and Landgrave of Thuringia from the House of Wettin.
Frederick IV, nicknamed the Peaceful or the Simple, was a member of the House of Wettin and Margrave of Meissen who ruled as the last independent Landgrave of Thuringia from 1406 until his death.
