Louis VI the Roman, Brandeburg margrave between 1351 and 1365, had to re-establish the Wittelsbach rule against the opposition of the Ascanians, which he accomplished by 1355. During this process, the Brandenburg-Pomeranian border in the Uckermark was finally settled in 1354. With the Golden Bull of 1356, only the Palatinate branch of the Wittelsbach family and Louis VI the Roman as Margrave of Brandenburg were invested with the electoral dignity, which caused a new conflict between Louis V and Charles IV.
