The Division of Altenburg (German: Altenburger Teilung) was the plan for the division of the Meissen lands [1] agreed upon by the two hostile Wettin brothers Elector Frederick II of Saxony and William III on 16 July 1445 at Altenburg. [2] The brothers had attempted to reconcile, but eventually the division led the Saxon Fratricidal War (German: Sächsischer Bruderkrieg), [3] which began in 1446 and lasted for five years, until the Peace of Naumburg was negotiated in 1451. [3] Following the peace, the subsequent Treaty of Eger in 1459, [4] 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.
By the 15th century, the noble house of Wettin and its line of Upper Saxon princes had gained a large amount of land over the years mainly through inheritance, including the Margraviate of Meissen and the Duchy of Saxe-Wittenberg, which was elevated to the Electorate of Saxony according to the Golden Bull of 1356. Margrave Frederick IV of Meissen became Saxon elector (as Frederick I) in 1423. Upon the death of his younger brother William II in 1425, he ruled over all Wettin lands except for the Landgraviate of Thuringia, held by his cousin Frederick the Peaceful. [5]
Elector Frederick ruled over his lands until his death in 1428. With his death, his four sons Frederick, William, Henry, and Sigismund took control. While Henry died in 1435 and Sigismund was forced to renounce his claims to become Bishop of Würzburg in 1440, only two sons, Frederick and William, now ruled over their family's land. As the eldest, Frederick II held the Electorate of Saxony and some land around Wittenberg in his own right, while he controlled the remainder of the land jointly with William. This continued peacefully and without serious incident until 1440, when their uncle Landgrave Frederick of Thuringia died childless and the two brothers inherited his extensive lands as well as the title of Landgrave of Thuringia. [6]
The brothers quarreled over the division of this new land in Thuringia and on 16 July 1445 the Saxon estates tried to reconcile them in the Division of Altenburg: Frederick II should retain the electoral dignity and the Margraviate of Meissen, while the younger William II should rule the –highly indebted– Landgrave of Thuringia up to the Osterland region in the east. However, when Frederick chose the western part and not the Margraviate of Meissen on 26 September 1445 in Leipzig, William furiously rejected the division. On December 11 of the same year the brothers again attempted to reconcile in the monastery of Neuwerk in Halle in what was known as the Hallescher Machtspruch (Halle Dictum). Archbishop Frederick III of Magdeburg, Elector Frederick II of Brandenburg and Landgrave Louis II of Hesse actively participated as judges. The division was even confirmed by the Habsburg king Frederick III, however the two brothers ultimately failed to reach a peaceful resolution.
In June 1446, one day after William's marriage with the Habsburg princess Anne of Austria, the split led to a war between the two brothers known as the Saxon Fratricidal War (Sächsischer Bruderkrieg). [3] The brothers continued fighting until peace was reached in a meeting at Naumburg on 27 January 1451. [3] Later, in the 1459 Treaty of Eger, Elector Frederick II, his brother Duke William III, and King George of Poděbrady fixed the borders between the Kingdom of Bohemia and the Saxon electorate. This border along the crest of the Ore Mountains is still current and is one of the oldest existing borders in Central Europe.
After Frederick's death in 1464, [7] his two sons Ernest and Albert III inherited his land. When Duke William III died in 1482, Ernest annexed Thuringia and returned it to Frederick's original line. Ernest then shared many of his lands in a second division with his brother, Albert, because of the Treaty of Leipzig on 26 August 1485. [8] [7] In this second division of the Wettin lands between Ernest and Albert, also known as the Division of Leipzig (Leipziger Teilung), Altenburg fell to Ernest, together with the electoral lands around Wittenberg, the Grimma estates, the Mutschener Pflege, Leisnig, large parts of Thuringia, and the Vogtland region around Plauen. From this time on, Altenburg was historically connected with Thuringia.
Following the multiple divisions and the Saxon Fratricidal War, the Wettins lost much of their power among the leading German noble families and houses, [5] most notably in favour of the rising Habsburg and Hohenzollern dynasties.
The House of Wettin is a dynasty of German counts, dukes, prince-electors and kings that once ruled territories in the present-day German states of Saxony, Saxony-Anhalt and Thuringia. The dynasty is one of the oldest in Europe, and its origins can be traced back to the town of Wettin, Saxony-Anhalt. The Wettins gradually rose to power within the Holy Roman Empire. Members of the family became the rulers of several medieval states, starting with the Saxon Eastern March in 1030. Other states they gained were Meissen in 1089, Thuringia in 1263, and Saxony in 1423. These areas cover large parts of Central Germany as a cultural area of Germany.
Saxe-Coburg was a duchy held by the Ernestine branch of the Wettin dynasty in today's Bavaria, Germany.
Saxe-Weimar was one of the Saxon duchies held by the Ernestine branch of the Wettin dynasty in present-day Thuringia. The chief town and capital was Weimar. The Weimar branch was the most genealogically senior extant branch of the House of Wettin.
Frederick II, The Gentle was Elector of Saxony (1428–1464) and was Landgrave of Thuringia (1440–1445).
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.
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.
Saxe-Eisenach was an Ernestine duchy ruled by the Saxon House of Wettin. The state intermittently existed at three different times in the Thuringian region of the Holy Roman Empire. The chief town and capital of all three duchies was Eisenach.
The Ernestine duchies, also known as the Saxon duchies, were a changing number of small states that were largely located in the present-day German state of Thuringia and governed by dukes of the Ernestine line of the House of Wettin.
The Electorate of Saxony was a state of the Holy Roman Empire established when Emperor Charles IV raised the Ascanian duchy of Saxe-Wittenberg to the status of an Electorate by the Golden Bull of 1356. It comprised a territory of some 40,000 square kilometers. Upon the extinction of the House of Ascania, it was feoffed to the Margraves of Meissen from the Wettin dynasty in 1423, who moved the ducal residence up the river Elbe to Dresden. After the Empire's dissolution in 1806, the Wettin Electors raised Saxony to a territorially reduced kingdom.
The Duchy of Saxe-Wittenberg was a medieval duchy of the Holy Roman Empire centered at Wittenberg, which emerged after the dissolution of the stem duchy of Saxony. The Ascanian dukes prevailed in obtaining the Saxon electoral dignity until their duchy was finally elevated to the Electorate of Saxony by the Golden Bull of 1356.
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 March or Margraviate of Lusatia was as an eastern border march of the Holy Roman Empire in the lands settled by Polabian Slavs. It arose in 965 in the course of the partition of the vast Marca Geronis. Ruled by several Saxon margravial dynasties, among them the House of Wettin, the lordship was contested by the Polish kings as well as by the Ascanian margraves of Brandenburg. The remaining territory was finally incorporated into the Lands of the Bohemian Crown in 1367.
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.
Margaret of Austria, a member of the House of Habsburg, was Electress of Saxony from 1431 until 1464 by her marriage with the Wettin elector Frederick II. She was a sister of Emperor Frederick III.
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.
