The Principality of Leiningen (de|Fürstentum Leiningen) was a short-lived principality ruled by the Prince of Leiningen.
The principality emerged in 1803 in the course of secularization and was created when the princely branch of the House of Leiningen, which had been raised to the rank of a Prince of the Holy Roman Empire in 1779, was deprived of its lands on the left bank of the Rhine by France, namely at Dagsburg, Hardenburg and Dürkheim, and subsequently received the secularized Amorbach Abbey as an ample compensation in 1803.[1]
A few years later, the Principality of Leiningen was mediatized in 1806.[2] Its territory is now included mainly in Baden-Württemberg, but partly in Bavaria and in Hesse. Amorbach Abbey is still today the family seat of the Prince of Leiningen.
