The intervention of the [[Roman curia]], which hitherto had been hostile to Casimir, was due to the permutations of [[European politics]]. The pope was anxious to get rid of the [[Hussite]] King of Bohemia, George Podebrad, as the first step towards the formation of a league against the [[Ottoman Empire|Ottoman Turks]]. Casimir was to be a leading factor in this combination, and he took advantage of it to procure the election of his son [[Vladislaus II of Bohemia and Hungary|Vladislaus II]] as the [[Kingdom of Bohemia|King of Bohemia]]. But he would not commit himself too far, and his ulterior plans were frustrated by the rivalry of [[Matthias Corvinus]], King of Hungary, who even went so far as to stimulate the [[Teutonic Order]] to rise against Casimir. The death of Matthias in 1490 was a great relief to Poland, and Casimir employed the two remaining years of his reign in consolidating his position still further.{{sfn|Bain|1911|p=448}}

In 1490, Casimir's son [[John I of Poland|John Albert]] was elected the [[Kingdom of Hungary|King of Hungary]] by a party among the [[Hungarian nobles]]. He was, however, defeated by his older brother, King Vladislaus II of Bohemia. Casimir, who wanted to secure a separate realm for his sons, proposed John Albert. Most Hungarian barons and prelates preferred Vladislaus because his rule in Bohemia had indicated that he would respect their liberties. Vladislaus was crowned King of Hungary on 18 September 1490 in [[Székesfehérvár]].

Around 1480 Casimir was allied with the [[Great Horde]] against [[Grand Duchy of Moscow|Muscovy]] and [[Crimean Khanate|Crimea]]. His failure to support [[Ahmed Khan bin Küchük|Khan Akhmed]] at the [[Great stand on the Ugra River]] contributed to Russia's gaining its independence from the steppe nomads.
