The disputes between Protestants and Catholics escalated, leading to the Thirty Years' War in 1618, and the succession dispute became part of the war as the War of the Julich Succession. Ultimately, Brandenburg received Cleves-Mark and Neuburg received Jülich-Berg, after the lands had been trampled under military several times and lost much of the fabled wealth so renowned in Duke Wilhelm's time.
Among his court servants and employees were the composer Konrad Hagius.[6]
