a principality of Germany, situated near the former. It has not much arable land, but plenty of wood, good quarries of stone, some silver and vitriol, copper and lead, with store of iron, for the working and smelting of which there are many forges and founderies in the country; and by these, and the sale of their iron, the inhabitants chiefly subsist. Calvinism is the religion of the principality, which contains five towns and two boroughs, and belongs entirely to William V. prince of Orange, and Nassau hereditary stadtholder of the United Provinces, whose father succeeded to a part of it in 1739 on the death of Prince Christian, and to the rest in 1743 on the death of Prince William Hyacinth of Siegen. The prince, on account of this principality also and Dietz, has a seat and voice in the college of princes, at the diets of the empire and circle. His assentment in the matricula, for Nassau-Dillenbourg, is 102 florins monthly; and to the chamber judicatory, 59 rixdollars six and half kruitzers, each term. His revenue from this principality is computed at above 130,000 florins.
