According to the rules of the House of Welf, Duke Magnus II Torquatus of Brunswick would have been entitled to inherit.
Emperor Charles IV, however, regarded the imperial fief as having reverted to the Empire and enfeoffed Albert of Saxe-Wittenberg and his uncle Wenceslas with the principality, which triggered the Lüneburg War of Succession.
Only after the Battle of Winsen in 1388, in which Wenceslas lost his life, did the Wittenbergers renounce their claims and the principality was finally secured for the Guelphs.
[1] The Lüneburg War of Succession had led to a great deal of power among the estates in the principality.
[2] When the dukes approached the city of Lüneburg with another financial request,[3] in exchange for a loan of 50,000 marks, an extensive contract was concluded, in which numerous privileges were given to the estates, and the dukes submitted to the jurisdiction of a council (Gremium) formed by the estates.
