Sobiesław Szybkowski: Polish-Hungarian Relations between 1437 and 1490. A Short Introduction
XIX that his predecessors had been unsuccessfully trying to organize since the fall of Constantinople in 1453. 63 However, Matthias acknowledged the importance of succession rights to Bohemia which were held by the descendants of Casimir Jagiellon. When Matthias decided that he would engage in the Bohemian conflict supporting the Catholic side, he tried to come to an understanding with Casimir. In order to do that, in April 1468, he sent a legation to the Polish king, which was led by his Bohemian ally, Tas of Boskovice, Bishop of Olomouc. The legates sent by Matthias notified the Polish king about the fact that Corvinus, along with the Bohemian Catholics, started a war against George of Poděbrad. They encouraged Casimir to support these military actions. They also acknowledged the rights of Casimir and his sons to Bohemia. During a secret audience, the Bishop of Olomouc presented Matthias’s plan concerning his marriage with Hedwig Jagiellon, the daughter of Casimir and Elisabeth. Obviously, this way Corvinus would have acquired succession rights to Bohemia and to Hungary as well. Their younger daughter, Sophia, was supposed to marry Maximilian, the son of Emperor Frederick III. Casimir Jagiellon did not respond to the proposal made by Tas.64 After Moravia, Silesia and Lusatia submitted to Matthias, the Catholic Bohemian estates elected him King of Bohemia (Olomouc, 3 May 1469). However, Bohemia proper and Prague were still controlled by George of Poděbrad. In exchange for Casimir’s help, George offered the Polish king to appoint his son, Vladislaus, as his successor to the Bohemian throne. In 1469 this idea was approved by the Bohemian Diet under certain conditions (for example Vladislaus was supposed to marry George’s daughter, Ludmila, and give freedom of worship to Utraquists). At that point, the Polish king postponed his decision once again. It is believed that he wanted to preserve peace with Hungary.65 There were other pretenders who wanted to make use of his indecisiveness: Albert the Bold of the Wettin dynasty, Duke of Saxony (and the husband of Sidonie, another daughter of King George) and Matthias Corvinus himself, who offered George a settlement and agreed to return the occupied lands of the Bohemian crown. The Hungarian king was also going to consolidate his cooperation with the Habsburgs, but after the congress of Vienna in 1470 Emperor Frederick III actually decided to join the opponents of Matthias. Frederick was afraid that if Corvinus ruled over the whole Kingdom of Bohemia (which would have given him the right to be one of the Electors of the Holy Roman Empire), in the 63 Kalous, 2009. 144–145., 244–247. 64 Długosz, Lib.
