Sobiesław Szybkowski: Polish-Hungarian Relations between 1437 and 1490. A Short Introduction
XVIII The conflict over the Kingdom of Bohemia and its internal conflicts were related to the complicated international and internal situation. George of Poděbrad, who ruled the country since 1458, was an Utraquist and the leader of the local Hussite movement. The Bohemian Catholics were displeased with his rule. The Catholic faction had the upper hand in certain parts of the Kingdom of Bohemia, namely in Moravia, Silesia and Lusatia. This faction was supported by the papacy, whose aim was to eliminate the Hussite movement in Bohemia. In 1462 Pope Pius II annulled the Compacts of Prague of 1433 which had given the Bohemian church the right to autonomy, including the freedom of Utraquism. However, the Catholic opposition did not sit idle and in 1465 it formed the so-called League of Zelena Horá which challenged the authority of the Hussite king. A complete breakup between Rome and George took place in 1466, when Pope Paul II excommunicated the King of Bohemia, removed him from the throne and relieved his subjects of the duty of obedience towards him.60 The Catholic opposition was looking for support in its fight against George and approached Casimir Jagiellon, King of Poland, offering him the Bohemian crown and pointing out that his wife, Elizabeth of Austria (the sister of Ladislaus the Posthumous), and also their children held hereditary rights to Bohemian lands (Bohemia proper, Moravia and Silesia). However, Casimir thought that George’s rule was legitimate and on top of that he had been in an alliance with George since the congress of Głogów held in 1462.61 Since King Casimir was hesitating, the Catholic lords approached Matthias Corvinus, King of Hungary, who had been in close contact with them for a long time. The result was that in 1468 the Hungarian ruler, acting as an ally of papacy and Emperor Frederick III, took Bohemian Catholics under his protection and started a war against George.62 It needs to be emphasized that Corvinus was supported by the Pope, with whom he had maintained dynamic and exemplary relations. Therefore, it is not surprising that Pope Paul II saw him as the ruler who would overthrow the heretic king of Bohemia and then lead an anti-Turkish crusade 60 Baczkowski, Krzysztof: Stanowisko kurii rzymskiej wobec jagiellońskiej ekspektatywy na tron czeski.
