(1296–1335), second son, under tutelage of: Bolko I the Strict (1296–1301), son of Bolesław II King Wenceslaus II of Bohemia (1301–1305) Bolesław III the Generous (1305–1311), eldest son of Henry V, Duke of Legnica since 1296 As Henry VI left no male heirs, his lands were inherited by King John of Bohemia. Maps The following maps illustrate continuing fragemtarization of the Duchy of Silesia, and shifting borders of the individual smaller duchies. Aftermath After the inheritance of Bohemia by the House of Habsburg in 1526, the Silesian duchies gradually passed under control of the Austrian Habsburg monarchy until King Frederick II of Prussia invaded Silesia in 1740 and annexed most of it during the First Silesian War. The bulk of the duchy, enlarged by the County of Kladsko and Upper Lusatian territories annexed from Saxony, was subsequently reorganized as part of the Prussian Province of Silesia, while the duchies remaining under Austrian control were reconstituted as the Duchy of Upper and Lower Silesia in 1742. The duchies which had remained in Poland were subsequently annexed by the Kingdom of Prussia (New Silesia) and the Habsburg monarchy (Galicia) during the 18th century Partitions of Poland. The Duchy of Upper and Lower Silesia lasted as a crown land of Cisleithanian Austria until 1918, whereupon it was divided between the Second Polish Republic (Autonomous Silesian Voivodeship) and Czechoslovakia (Czech Silesia) after the Polish–Czechoslovak War of 1919.
