Biography
George William, Duke of Liegnitz (1660–1675), was the last Piast ruler of the Silesian duchies. He inherited Legnica and Brzeg at age twelve, but his reign was brief and managed by regents. Silesia at the time fell under Catholic Habsburg suzerainty, while the Piast dukes remained Protestant. George William was the final male descendant of the Polish Piast dynasty, which traced its origins to Piast the Wheelwright in the 9th century. He died of smallpox at fifteen, leaving no male heir. With his death, the direct Piast line—which had produced kings and dukes for over 700 years—ended. His lands passed to the Habsburg Emperor, extinguishing indigenous Silesian Piast rule.
