About Frederick William II, Prince of Nassau-Siegen
Frederick William II, Prince of Nassau-Siegen (11 November 1706 in Siegen – 11 November 1734 in Siegen) was the last Prince of Nassau-Siegen from the Calvinist line.
He was the eldest son of Frederick William Adolph (1680–1722) and his wife, Elisabeth of Hesse-Homburg (1681–1707).
He was only 16 years old when he inherited the principality and was unable to lead it out of its financial crisis.
He died in 1734 without a male heir.
Emperor Charles VI then enfeoffed Nassau-Siegen to William IV of Orange-Nassau-Dietz.
