 The final normalization of the relations between Bolko II and the new Holy Roman Emperor and German King Charles IV (also King of Bohemia after he succeeded his father) only occurred as a result of the mediation of Duke Albert II of Austria on 16 August 1350.After the signing of the treaty of 1350, Bolko II began the process of rapprochement with the House of Luxembourg.This was done without sacrificing his good relations with the Kings Casimir III of Poland and Louis I of Hungary.
