Wenceslaus IV of Bohemia

Born into the House of Luxembourg on 26 February 1361, Wenceslaus became King of the Romans and King of Germany at fifteen in 1376, then inherited Bohemia two years later in 1378. He added Duke of Luxembourg to the collection in 1383. But the accumulation didn't hold: he lost Luxembourg in 1388, and in 1400 his fellow electors stripped him of the German kingship in a formal deposition. Only Bohemia remained, and he ruled it until his death on 16 August 1419, outlasting the titles that slipped away but never shaking the epithet that stuck.
