The Duchy of Brzeg (Polish: Księstwo Brzeskie) or Duchy of Brieg (German: Herzogtum Brieg), (Czech: Knížectví Břežské) was one of the Duchies of Silesia, created in 1311 during the fragmentation of the Duchy of Wrocław. A Bohemian fief from 1329, it was ruled by the Silesian Piasts until their extinction in 1675. Its capital was Brzeg in Lower Silesia.
When the Piast duke Henry V of Wrocław and Legnica died in 1296, his sons and heirs were still minors and his estates were ruled by their uncle Duke Bolko I the Strict of Świdnica, succeeded by their maternal uncle King Wenceslaus II of Bohemia in 1301 and by the Wrocław bishop Henryk z Wierzbnej in 1305. Finally in 1311, Henry's bequests were divided among his sons: Bolesław III the Generous, the eldest brother, received the southeastern lands around Brzeg and Grodków.
Soon after however, Bolesław insisted on his rights as the firstborn son and ousted his younger brother Władysław from the Duchy of Legnica. He maintained good relations with his brother-in-law, the Luxembourg king John of Bohemia, and declared himself a Bohemian vassal in 1329.
