Sigismund I

 

(in Hungarian, Zsigmond; in Czech, Zyk-mund). Born Feb. 15, 1368, in Nuremberg; died Dec. 9, 1437, in Znaim (now Znojmo, Czechoslovakia). Holy Roman Emperor from 1410 to 1437, king of Hungary from 1387 to 1437, and king of Bohemia from 1419 to 1421 and in 1436 and 1437.

The son of Emperor Charles IV, Sigismund was the last of the Luxembourg dynasty. He became king of Hungary after marrying the daughter of King Louis the Great of Hungary. He led a crusade of Western European feudal lords against the Turks but was defeated by Bayazid I at the battle of Nicopolis in 1396. He was one of the initiators of and a participant in the church’s Council of Constance (1414–1418); at the council, he sanctioned the execution of J. Hus, to whom he had given a written guarantee of safe conduct. Inheriting the Bohemian throne on the death of his brother Václav IV, Sigismund waged a struggle against the Hussite revolutionary movement, organizing with the pope crusades against the Hussites. In 1421 he was deposed from the Bohemian throne by the diet of Čáslav; however, in 1436 he was again proclaimed king by the diet of Jihlava.
