Emperor Of Germany Sigismund, the last of the Luxemburg line, born in 1368, died Dec. 9, 1437. He was the second son of the emperor Charles IV., and became elector of Brandenburg, while his elder brother Wenceslas succeeded to the empire in 1378. He was affianced to Mary, daughter of Louis the Great of Hungary and Poland, and was designated as successor in both kingdoms. But on the death of Louis, in 1382, the Poles rejected him, while an adverse party in Hungary raised Charles the Little of Naples to the throne. Charles was assassinated, and Sigismund, having espoused Mary, was crowned king of Hungary (1387). He fought the Turks, was routed by Bajazet at Nicopolis in 1396, and fled to Greece; and when after several years he returned to Hungary, he had to contend against a new rival, Ladislas of Naples, who finally withdrew in 1403. In 1400 the incapable emperor Wenceslas had been deposed and succeeded by Rupert of the Palatinate, and on the death of the latter in 1410 Sigismund and his cousin Jodocus of Moravia contested the imperial crown. The electors were at first divided, but on the death of Jodocus in 1411 Sigismund was elected. He called a general council at Constance, violated the safe-conduct accorded to Huss, and provoked the great Hussite war.
