Вацлав IV
Despite his clergy state, Konrad IV also was interested in politics. Already in 1402 he joined to the newly alliance between the Silesian princes. In 1409 he stood with his father at the side of King Wenceslaus IV of Bohemia in the conclusion of a truce between Poland and the Teutonic Knights. In 1412 Konrad IV acted as mediator in the conflicts between the Dukes of Opole, King Wenceslaus IV and the city of Wrocław. Finally, in 1416 together with his brothers, he joined the alliance with the Master of the Teutonic Knights, Michael Küchmeister von Sternberg, against Poland.
