Herzogtum Liegnitz
In March 1409 Duke Wenceslaus II of Legnica, Bishop of Wroclaw, declared Louis II as his heir over the Duchy of Legnica and the half of Złotoryja. The rights over the other half of Złotoryja and a rent of 6,000 fines were assigned to Henryk IX. Wenceslaus II also decided also that both brothers had the option to take control over all Złotoryja if one pay the other in compensation. In the same year Louis II purchased to Henry IX his part of Złotoryja. At this point, the Duke of Lubin (already infuriated by the favoritism of Wenceslaus II over Louis II) and his younger brother broke their friendly relations. Soon the dispute turned into an open war, issued by Henry IX, which is going during the years 1411-1414. The war continue despite the mediation of Wenceslaus II, who tried to persuade Henry IX to stop. The dispute only ended thanks to the action of King Wenceslaus IV, who forbade his vassals to fight. The brothers were finally reconciled and issued a document on mutual help. The residents of the Duchy of Legnica-Złotoryja were obliged to paid homage to both Dukes. Henry IX died between 1419 and 1420. The place of his burial is unknown.
