Ladislas (Hun. Laszlo), Saint, king of Hungary (1077-95). See Hungary.
Ladislas (Pol. Wladystaw) II., king of Poland, born in Lithuania about 1350, died in Grodek, near Lemberg, Galicia, May 31, 1434. He was the son of Olgerd and grandson of Gedimin, grand dukes of Lithuania, and as a pagan prince, though the son of a Christian mother, received the name of Jagello or Ja-giello. He succeeded his father in Lithuania, and in 1386, having married Hedvig, the beautiful and pious young daughter of Louis the Great, king of Hungary and Poland, became a Christian and received the Polish crown. He converted Lithuania to Christianity, and finally united it with Poland. He was successful in his wars against the Teutonic knights, whom he routed in the battle of Grunwald (1410). He greatly contributed to the development of the power of his kingdom, which was ruled by his dynasty down to 1572, when it became an elective state. - His son and successor, Ladis-las III., having been elected king of Hungary (as Uladislas I.), waged war with the Turks, made peace with them, broke his oath, and fell in the battle of Varna (1444). He was succeeded in Poland by his brother Casimir IV.
