Title: House of Urach
Content:  hereditary seat of the dukes. Like the ducal trust, the title Duke of Urach was hereditary by agnatic primogeniture in the legitimate descent of the first duke, with cadets and females bearing the title of Prince/Princess of Urach (the royal letters patent mandated use of the term Fürst/Fürstin for "Prince/Princess" rather than the term Prinz/Prinzessin. Although both words translate as "prince" in English, Fürst, when used for cadets and not referring to a reigning sovereign, indicates noble rather than dynastic status, whereas Prinz was usually confined in use to cadets of ruling and mediatized families). In Württemberg, only dynasts descended in male-line from the nation's kings were titled Prinz, while those descending from the first king's brothers remained dukes). The name and title Count/Countess von Württemberg was explicitly preserved for the Urach dukes and princes rather than being replaced by the higher titles.
Title: Duke of Urach
Content:  Wilhelm, 1st Duke of Urach, was the son of Duke Wilhelm of Württemberg (1761-1830) and his morganatic wife, Baroness (Freiin) Wilhelmine von Tunderfeldt-Rhodis (1777-1822), whom he married at Coswig on 23 August 1800. His paternal grandfather was Duke Friedrich II Eugen (1732-1797), from whom all claimants to the Kingdom of Württemberg are descended. Because of his first marriage to Théodolinde de Beauharnais, the first Duke had converted to Roman Catholicism. His second marriage to Her Serene Highness Princess Florestine of Monaco in 1863 led in part to Wilhelm's elevation in 1867 from being a Count of Wurttemberg to Duke (Herzog) von Urach. He had served the Kingdom well in his career, and the dukedom of 1867 elevated him to his wife's rank of Serene Highness. His new title was similar to the status of a Royal Duke in Britain today. The 2nd Duke of Urach was briefly chosen as Mindaugas II, King of Lithuania in 1918. In the same year the Monaco Succession Crisis of 1918 ended his claim through his mother to the throne of Monaco. The family still owns Lichtenstein Castle, rebuilt by the first duke in the 1840s.
