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.
Prussia's power grew and in 1772, under King Friedrich II (Frederick the Great), consisted of the provinces of Brandenburg, Pomerania, Danzig, West Prussia and East Prussia (modern day East Germany, northern Poland, and a small portion of the Soviet Union).
