Principality of Nassau-Usingen
Origins
Nassau-Usingen was created in 1659 when the lands of Nassau-Saarbrücken were divided among the sons of Count William Louis, and Walrad received Usingen in the Taunus. Walrad, a general in Dutch and imperial service, was raised to prince in 1688.
Rule and society
The territory was Lutheran and mostly rural, but it grew as other Walramian lines died out: Nassau-Usingen inherited Nassau-Saarbrücken and Nassau-Idstein in the 18th century. Prince Charles moved the residence to Biebrich Palace on the Rhine, near Wiesbaden, in 1744, and the spa town of Wiesbaden grew under the princes. After 1797 it lost its left-bank lands but gained Mainz territory in 1803.
Decline and legacy
In 1806 Nassau-Usingen and Nassau-Weilburg united as the Duchy of Nassau within the Confederation of the Rhine, with Frederick Augustus of Usingen as duke. When he died without sons in 1816, the Usingen line ended and Nassau passed to the Weilburg line.
