In 1439, his 15 year old brother Wladyslaw was elected King of Hungary and Croatia after Albert the Magnanimous death, but the thrown was disputed between Queen Elizabeth of Bohemia and former Duchess consort of Austria from the House of Luxembourg which caused civil war and shortly after Albert died she gave birth to Ladislaus the posthumous, Elizabeth suddenly died in 1442, Ladislaus succeeded her.
The Crusade of Varna took place on 10th November 1444 they were fighting against Ottomans led by Sultan Murad II, Wladyslaw commanded the army, John Hunyadi and Mircea II Voivode of Wallachia acted as commander of the combined Christian forces, the Ottomans won and expanded into the Balkans, Wladyslaw disappeared in battle, his cadaver and armour were never found, his rival Ladislaus succeeded him and John Hunyadi served as regent.
Grand duke Michael of Lithuania suddenly died in 1452, he chose Alexander Olelkovich prince of Koper and Slutsk to succeed him, but Jonas Goštautas voivode of Trakai and magnates of Lithuania, supported Casimir as a candidate for the Lithuanian throne.[1]
In 1454, Casimir married Elizabeth of Austria, Bohemia, Hungary and Poland sister of his brother's rival Ladislaus the Posthuumous, he married her so Lithuania could maintain influential relations with the Holy Roman Empire and Duchy of Austria, in the same year, Casimir was approached by the Prussian Confederation for aid against the Teutonic Order by making the separatist Prussian regions a protectorate of the Polish Kingdom. However, when the insurgent cities rebelled against the Order, it resisted and the 13 Year's War (1454–1466) ensued.
