NASSAU-SIEGEN, a small principality of Germany in the Westerwalde, is in general a mountainous woody country, with some arable and pasture ground, and a good breed of cattle. Its manufactures are chiefly those of iron and steel, having an iron mine in the neighbourhood of Siegen. Count John the Younger, in 1626, embraced the Roman Catholic religion, and endeavoured to introduce it into the country; but the principality, upon the extinction of the line of Nassau-Siegen in 1743, falling to the line of Nassau-Dietz, and therein to the prince of Orange, hereditary stadtholder of the United Provinces, the Protestants were delivered from their apprehensions of Popish tyranny and bigotry. The prince, on account of these territories, has a seat and voice at the diets of the empire and circle in the college of princes. His assentment in the matricula for Nassau-Siegen is 773 florins monthly; and towards the maintenance of the chamber judicatory, 50 rixdollars, six kruitzers and a half, each term. The revenue of this principality is estimated at 100,000 rixdollars.
