Coat of arms

The Duchy of Głogów (Polish: Księstwo głogowskie, Czech: Hlohovské knížectví) or Duchy of Glogau (German: Herzogtum Glogau) was one of the Duchies of Silesia ruled by the Silesian Piasts. Its capital was Głogów in Lower Silesia.

In 1177, under the rule of Konrad Spindleshanks, the youngest son of High Duke Władysław II the Exile of Poland, the town of Głogów had already become the capital of a duchy in its own right. However when Konrad died between 1180 and 1190, his duchy was again inherited by his elder brother Bolesław I the Tall, Duke of Wrocław. After the death of Bolesław's grandson Duke Henry II the Pious at the 1241 Battle of Legnica his sons in 1248 divided the Lower Silesian Duchy of Wrocław among themselves. Konrad I, a child when his father died, claimed his rights too and in 1251 and received the northern Głogów territory from his elder brother Bolesław II the Bald, then Duke of Legnica.
