Wenceslaus IV of Bohemia
The Free imperial cities in the south of the Holy Roman Empire aimed towards defending their liberties against the territorial expanding states of Bavaria, Austria and Württemberg. The trigger for the war was a pact between the Swabian League of Cities and the archbishop of Salzburg, Pilgrim von Puchheim, both antagonists of Bavaria. This pact would have surrounded Bavaria from two sides. Bavaria took the Bishop captive and demanded the dissolution of the pact. German king Wenceslaus IV of Bohemia declared a "Reichskrieg" (ger. war of the realm) against Bavaria.
