Duchy of Nysa
The settlement in the Silesian Duchy of Nysa was probably founded with Bílá Voda Castle in the 13th century. From 1507 onwards the Prince-Bishops of Wrocław had the castle rebuilt as a summer palace. "Weißwasser" was first mentioned in a 1532 deed. Jakob Ernst von Liechtenstein-Kastelkorn, the later Bishop of Olomouc, established a Piarist college on his inherited Bílá Voda estates in 1723, a response to the 1707 Convention of Altranstädt granting religious freedom to the Silesian Protestants. When the Prussian king Frederick the Great conquered most of Silesia in 1742, the Duchy of Nysa was divided and Bílá Voda became a border town of Austrian Silesia, after World War I part of the newly established state of Czechoslovakia. In 1930, Bílá Voda had a population of 1104, of which 941 were German-speaking. Upon the 1938 Munich Agreement the area was annexed by Nazi Germany and incorporated into the "Reichsgau" Sudetenland. After 1945 the German population was expelled according to the Beneš decrees.
