Louis of Oettingen-Wallerstein
Ludwig Kraft Ernst, Prince of Oettingen-Wallerstein (31 January 1791, Wallerstein - 22 June 1870, Luzern) was a German nobleman of the House of Oettingen-Wallerstein. His mother was Wilhelmine Friederike (1764-1817), a daughter of Louis Eugene, Duke of Württemberg. He succeeded his father as ruling Fürst in 1802 and lost his sovereignty in 1806 due to Mediatisation.
He served as minister of the interior in the Kingdom of Bavaria between 1832 and 1837 and as foreign minister in 1848/49. From 1849 until 1859 he was a liberal member of the Bavarian Upper House of Parliament.
In 1823 he married Maria Crescentia Bourgin (1806–1853) in a morganatic marriage, thus being stripped of his headship of the House, and after her death he married Countess Albertine Larisch von Moennich. As an art collector he spent almost all of his means for artworks and had to move to Switzerland after having been arrested in 1862 on request of his creditors.
