The Conflict Over the Archbishopric of Riga Between the Szczecin Dukes and the Teutonic Order in Prussia in the Years 1394–1403 in Light of the Latest Research

Summary/Abstract: On April 30, 1388, an agreement on mercenary service was concluded in Świecie on the RiverVistula between Pomeranian Dukes Swantibor I and Bogislaw VII, Grand Master Konrad Zöllner von Rotenstein, and the Order. The document obliged the Pomeranian rulers toprovide the Teutonic Knights with military assistance when need be, for a decade. It alsoforbade allying with the enemies of the Order for the same period of time. The agreementwas strengthened by a non-returnable subsidy of 6,000 guilders and a loan of 2,000 threescores of Czech grosches intended for the House of Griffins.In this period, Swantibor I was closely associated with the court of the Roman King WenceslausIV where he served as court judge. In 1391, the then Archbishop of Riga, Johannes vonSinten, as a result of a conflict with the Livonian branch of the Teutonic Order, left Livoniafor, first, Lübeck and, then, Prague. Submitting the candidacy of his son Otto II for thefunction of the metropolitan bishop of Riga, the Duke of Szczecin at first received the supportfor his intentions of Roman King Wenceslaus IV, Polish king Władysław II Jagiełło andVytautas the Great. Archbishop Johannes von Sinten was removed from office in September1393, and Pope Boniface IX appointed Johannes von Wallenrode, nephew of the formerGrand Master Konrad von Wallenrode, as the new ordinary. In November 1394, the faithfulcanons of Archbishop Johannes von Sinten, elected Otto II Archbishopric of Riga. The duke managed to reach Livonia, where on March 5, 1396, as a coadjutor of Riga, he managed tomake an arrangement with Vytautas the Great.Due to divergent political goals, the ad hoc coalition formed for Otto II eventually fell apart,whereas the young representative of the House of Griffin was compelled to leave the archdiocese.These events led Duke Swantibor I to terminate, by the end of 1396, his agreement withthe Teutonic Knights. The duke blamed Grand Master Konrad von Jungingen and the Orderfor the failure of Otto II. The conflict between Szczecin and the Teutonic Order ended withthe conclusion, on April 2, 1403, of an agreement with Grand Master Konrad von Jungingenin Hammerstein.
