From 1560 until 1725, Hardenburg Castle was the main seat of the branch. After its partial destruction during the Nine Years' War, the residence was moved to Bad Dürkheim.
A few years later, the short-lived Principality of Leiningen at Amorbach was mediatized. Its territory is now included mainly in Baden, but also partly in Bavaria and in Hesse. Amorbach Abbey is still today the seat of the Prince of Leiningen. A former hunting lodge named Waldleiningen Castle at Mudau is now run as a hospital by the family.
In 1991, the seventh prince, Emich, disinherited his eldest son, the Hereditary Prince Karl Emich, after he married his second wife, Dr Gabriele Thyssen, on May 24 of that same year. The disinheritance was upheld by the German courts, and so on Emich's death later that year, he was succeeded by his second son, Andreas, who has been the eighth prince from that time. He married Princess Alexandra of Hanover.
