After the French troops were expelled from Germany in 1813, the Prince of Orange could retake the territories that were lost to the Grand Duchy of Berg in 1806. In addition, the following mediatised areas were added under his sovereignty: the "Herrlichkeit" of Westerburg, the "Herrlichkeit" of Schadeck, and that part of the county of Wied-Runkel that lay on the right bank of the river Lahn. On 26 November 1813, the Prince of Orange concluded a treaty with the Duchy of Nassau, in which the county of Nassau-Dietz was returned to the prince. The "Amt" Wehrheim, however, remained with the Duchy of Nassau.
