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.
In 1226, Prussia was conquered by the Teutonic Knights, a military religious order, who converted the Prussians to Christianity. The Teutonic Knights were overthrown by the Prussians with help from Poland and Lithuania in 1454. Prussia was divided into Royal Prussia in the west and Ducal Prussia in the east. Royal Prussia was incorporated into Poland providing it with a corridor to the Baltic Sea (the Danzig Corridor). Ducal Prussia became a Polish territory.
