リュネヴィルの和約
In the Treaty of Lunéville in 1801, the Electorate of Mainz lost its worldly territory, including the Imperial fief of Kronberg, which was confiscated by the Prince of Nassau-Usingen in 1802, and formally awarded to him in 1803. In the Austro-Prussian War of 1866, the Duke of Nassau sided with Austria, thereby losing his land to Prussia.
