Moritz, Prince of Dietrichstein (Moritz Joseph Johann; 19 February 1775 – 29 August 1864), was a German prince member of the House of Dietrichstein, 10th and last Prince (Fürst) of Dietrichstein zu Nikolsburg, Count of Proskau-Leslie, Baron (Freiherr) of Hollenburg, Finkenstein and Thalberg.

Born in Vienna, he was the seventh child and fourth (but third surviving) son of Karl Johann Baptist, 7th Prince of Dietrichstein, and , a daughter of Jan Josef František Antonín, Count of Thun-Hohenstein.

Life[]

Being the third son of his family and in consequence without expectations to inheritance, since 1791 Moritz entered in the Austrian military service. In 1798 was named Adjutant of General Karl Mack von Leiberich in Naples, where he was captured with his master by the French, and after his release he participated the campaign in Ulm (1805).

In 1815 Moritz was appointed tutor of the Duke of Reichstadt (Napoleon II) and later was named Director of the Imperial Court Theatre (Burgtheater) and Library (Kaiserlichen Bibliothek), in 1845 was named Oberstkämmerer until 1848, when he retired from public offices.

Like his older brother, Prince Franz Joseph, he was an opponent of Metternich politics. Beethoven was very encouraged by him. In 1838 Moritz acquired from the Austrian National Library the Mozart's Requiem. Even as a Director of the Coins and Antique Cabinets (Münz- u. Antikenkabinetts) during 1833-1848 he rendered great services, composing songs, dances and minuets. In 1834 he was elected an honorary member of the Bavarian Academy of Sciences and Humanities (Bayerische Akademie der Wissenschaften).

After the death of his nephew, Joseph Franz on 10 July 1858, Moritz succeeded him as 10th Prince of Dietrichstein.

Moritz died in Vienna aged 89, and was buried at Hietzinger cemetery, grave 06, no. 15. Because his only son died before him and without issue, with Moritz ended the Dietrichstein family in male line. Four years later, in late 1868, Count Alexander of Mensdorff-Pouilly (husband of Moritz' grand-niece), obtained from the Emperor the title of Prince of Dietrichstein-Nikolsburg, thus reviving the title of his wife's family.
