Throughout a large part of its history, the region had been ruled by the Duchy of Opole and other Silesian duchies, formed as a result of the medieval fragmentation of Piast-ruled Poland. Following the Silesian Wars the region found itself within Prussia, and from 1871 it was also part of Germany. Following Germany's defeat in World War II in 1945, in accordance with the Oder–Neisse line, Opole Silesia became again part of Poland.
