Politics and world events



First documentary mentions


  • Arnold II von Wied is elected Archbishop of Cologne by the clergy and the people . He takes over the office in an extremely difficult situation: The Archbishopric of Cologne is heavily in debt and weakened by feuds. Therefore Arnold declares himself unable to lead the archbishopric and only wants to accept the election with the express consent of the emperor and pope. It plays a role that he fears that his private fortune will be used to reduce the debts of the archbishopric. Arnold meets with King Konrad in the church of Schwarzrheindorf. There the altars of the lower church are consecrated by Albrecht I of Meissen and Heinrich von Lüttich . Arnold himself consecrates the altar of the upper church. Arnold and Konrad travel by ship to Cologne, where they receive an enthusiastic reception. In Cologne Cathedral , King Arnold gives the regalia and he is also granted ducal rights to the extinct Lorraine ducat. In the late summer Arnold travels to Rome with Wibald from Stablo .
