Wenceslaus II of Bohemia

Born in 1271 to Ottokar II of Bohemia and Kunigunda, daughter of a Slavonian lord with Kievan and Hungarian royal blood, Wenceslaus was the only son to survive and inherited Bohemia at seven when his father died in 1278. He became Duke of Cracow in 1291, then King of Poland five years later in 1296, holding all three titles until his death. A Přemyslid with a German king for a great-grandfather, he left behind a grandson who would become Holy Roman Emperor Charles IV. He died in June 1305 at thirty-three.
