Duchy of Głogów

The Duchy of Głogów was the Silesian Piast duchy of Lower Silesia, a fragment of Poland's medieval breakup that lived, with interruptions, from 1177 into modern times. Konrad Spindleshanks, youngest son of High Duke Władysław the Exile, made Głogów his capital in 1177, lost it back to Silesia on his death, and after Henry the Pious fell at Legnica in 1241 his sons split the inheritance, Konrad the younger taking Głogów in 1251. Under the rule of Konrad's son Henry III the size of the principality was fluctuating, Ścinawa and Żagań splitting off in 1273. Przemko's childless death in 1331 gave the duchy to Bohemia as a fief, Charles halving it between the crown and Henry of Iron in 1349, and the Piast line dying with Henry XI in 1476, John Corvinus and Jagiellonians following, then Habsburgs, the town remaining its head through every transfer into modern times.
