The Second Peace of Thorn (1466) split Prussia into the western Royal Prussia, a province of Poland, and the eastern part, from 1525 called the Duchy of Prussia, a fief of the Crown of Poland up to 1657.
After defeat in World War I, Germany was forced to give up the Danzig Corridor to Poland and Danzig once again became a free city. This caused the province of East Prussia to be separated from the rest of Germany. The Rosenberg District was at this time contained in East Prussia.
