In Prussia (1742-1945)
Most of Silesia became Prussian in 1742 after the First Silesian War and turned into the Silesian province, divided into the districts of Lower Silesia (Liegnitz), Middle Silesia (Breslau), and Upper Silesia (Oppeln). After World War I, Upper Silesia was divided between Germany, Poland and Czechoslovakia. The German portion was reorganized into two provinces: Lower Silesia and Upper Silesia.
In Poland (after 1945)
After World War II most of Lower Silesia was assigned to Poland by the Allies and reorganized into Wroclaw Voivodship (1945-1975). The German population was forcefully expelled. As a result of Local Government Reorganisation Act (1975) Poland's administration was reorganized into 49 voivodships, 4 of them in Lower Silesia:
Jelenia Gora Voivodship,
Legnica Voivodship,
Walbrzych Voivodship
Wroclaw Voivodship (this would be the Zeise-Tischer-Wurm home)
(1975-1998)
As a result of Local Government Reorganization Act of 1998, these 4 provinces were joined into the Lower Silesian Voivodship (effective 1 January 1999), whose capital is Wroclaw.
