マイセン辺境伯
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.
