Sobiesław Szybkowski: Polish-Hungarian Relations between 1437 and 1490. A Short Introduction
XXII Corvinus was supposed to choose one of these rulers until 8 May 1473 and eventually opted for Charles the Brave. 71 However, the congress in Troppau did not start until 13 September. It was also overshadowed by a raid of Polish mercenaries who were members of the campaign led by Prince Casimir. They invaded Upper Hungary and occupied a few castles. Officially, Casimir did not know that a raid had been planned, but it cannot be ruled out that in reality he used his mercenaries to put more pressure on the Hungarian king during the negotiations in Troppau. The congress yielded no binding arrangements, except for prolonging the peace treaty between Poland and Hungary.72 However, its regulations were not observed since after the congress in Troppau more Polish mercenaries joined those who had already been stationed in Upper Hungary. The Hungarian army led by the king himself managed to defeat these troops and took the occupied castles only in December 1473. In January 1474, the Hungarian army, which numbered a few thousand knights, retaliated and attacked the border regions of Southern Lesser Poland, and seized a few cities there. Finally, a Polish-Hungarian congress in Spišská Stará Ves put an end to these fights. On 21 February 1474, a peace treaty was signed between Poland and Hungary, and a three-year-armistice was agreed upon as well between Bohemia and Hungary. The peace treaty between Poland and Hungary provided for preserving the status quo on the border, which meant that Hungarian troops had to leave the Polish cities which they held since January. It also regulated procedures related to settling disputes between the inhabitants of border regions. When it comes to Moldavia, it was decided that a separate congress would be held to determine whether it should be considered as a Polish fief. 73 However, soon after the negotiations in Stará Ves ended, the Jagiellons, with the help of Albert Achilles, Elector of Brandenburg, formed an alliance with Emperor Frederick III.74 The alliance was concluded Nuremberg in March 1474 and was forged against Matthias Corvinus. Its result was a military campaign in Silesia which took place in autumn. Casimir and Vladislaus Jagiellon provided their troops against the Hungarian king. However, the campaign was not successful for the Jagiellons. It ended in the peace of Wrocław which was 71 CEXV, Vol. III.
