Wenceslas, (b. 1361, Nürnberg, d. 1419, Prague), German king and, as Wenceslas IV, king of Bohemia, whose weak and tempestuous, though eventful, reign was continually plagued by wars and princely rivalries that he was unable to control, plunging his territories into a state of virtual anarchy until he was stripped of his powers altogether by a rebellious nobility.
Son of the Holy Roman emperor Charles IV, Wenceslas was crowned king of Bohemia in 1363 and king of the Romans in 1376, proving a largely incompetent ruler after his father's death in 1378. He was a peace-loving man and held frequent diets in Germany from 1378 to 1389, but he could not prevent the continuing wars between town leagues and princes that reduced Germany to anarchy for almost a decade. The diet at Eger (modern Cheb) in 1389 finally settled most conflicts by a general peace, but, because the King spent most of his time in Prague to the detriment of Germany, the empire's princes repeatedly demanded the appointment of a Reichsverweser (imperial governor) for Germany, a request consistently refused by Wenceslas.
After 1389 Wenceslas left Germany largely to its own devices, returning only in 1397 to hear the princes' complaints before travelling to France to attempt to resolve the Western Schism that was dividing Christendom. Finally, in August 1400, when Wenceslas refused to attend another meeting of the princes, they deposed him and elected Rupert (Ruprecht) III, elector Palatine, king of the Romans. Wenceslas was, however, able to retain the title of German king for the rest of his life.
Wenceslas' reign in Bohemia was even less successful than that in Germany. Constantly beset by jealous and ambitious relatives, he was in 1394 faced by a revolt of magnates led by his cousin Jobst, margrave of Moravia, who held the King prisoner in Austria. Wenceslas was shortly restored with German help but was stripped of virtually all his power in 1396, when he was forced to appoint Jobst governor of the realm and to entrust the government to a royal council mainly consisting of nobles. In 1402 his younger half brother Sigismund (later Holy Roman emperor), whom the King had aided in his successful quest for the Hungarian crown (1387), deposed Wenceslas in Bohemia. Once more imprisoned, Wenceslas was able to restore himself in the next few years, but at the price of yielding real power to the royal council. Subsequently, he grew inert and found solace in drinking. Although he initially supported the Bohemian religious reformers around Jan Hus, after the reformer's condemnation by the church, characteristically, the King did nothing to prevent his execution as a heretic (1415). Wenceslas was married twice, first to Joanna of Lower Bavaria (died 1386) and, from 1389, to Sophia of Bavaria. He had no children, and the Bohemian crown passed to Sigismund.
