Frederick VIII von Leningen

Leiningen is the name of an old German noble family whose lands lay principally in Alsace, Lorraine and the Palatinate.

Various branches of this family developed over the centuries and ruled counties with Imperial immediacy. Most of these were annexed by the First French Republic in 1793, when France conquered the Left Bank of the Rhine during the War of the First Coalition. Several family branches subsequently received secularized abbeys as a compensation, but shortly afterwards these new counties were mediatized and the family lost its immediacy. Today the only still existing branch are the Princes of Leiningen.
