Future Polish King Władysław I the Elbow-high, fighting the Teutonic Order, found shelter at the courts of the Aba and Záh (Nógrád Castle) clans in Hungary. Záh knights guarded Władysław's family. Władysław married a Polish-Byzantine-Hungarian princess, Jadwiga of Kalisz. The daughter of Władysław and of Maria of Bytom, Elżbieta, became queen of Hungary. Her son, king of Hungary, Louis the Great was also king of Poland 1370–1382, after the death of his uncle, Polish king Casimir III the Great. After the death of Louis the Great, his daughter Jadwiga became the ruler of Poland, crowned "king" in Poland's capital, Kraków, on 16 October 1384. In the 15th century, the two countries briefly shared a king: Poland's Władysław III of Varna, who died at age twenty, fighting the Turks at Varna, Bulgaria. During the 16th century, Poland elected as its king the Hungarian nobleman Stephen Báthory. In the Hungarian Revolution of 1848, the Polish General Józef Bem became a national hero of both countries.
