de Blacas d'Aulps, 7th Duke of Blacas (b. 1943). Duke of Blacas (1821) Duke of Blacas is a title in the Peerage of France. It was created by ordinance dated 30 April 1821 and Letters patent dated 11 September 1824 for Pierre-Louis de Blacas d'Aulps, only surviving son of Alexandre-Pierre de Blacas, Lord of Aulps, Vérignon, Fabrègues, etc., Knight of Saint-Louis (known as le marquis de Blacas). He was a member of the Government of the first Bourbon restoration from 13 May 1814 to 19 March 1815. The 1st Duke had been previously made an hereditary Peer (without specific rank) as early as 17 August 1815, and had been created Count of Blacas in the French Peerage by ordinance dated 31 August 1817, but having not been regulated by Letters patent, this previous comital title did not become hereditary. In 1830, he refused to recognize Louis-Philippe as King of the French and so lost his seat in the House of Peers. Later, he also received, by diploma dated 23 June 1838, the Austrian title of prince (Fürst von Blacas d'Aulps), hereditary in the male line (with the title of Count for cadet sons).
