The Grand Duchy of Oldenburg (German: Großherzogtum Oldenburg) (also known as Holstein-Oldenburg) was a grand duchy within the German Confederation, North German Confederation and German Empire which consisted of three widely separated territories: Oldenburg, Eutin and Birkenfeld. It ranked tenth among the German states and had one vote in the Bundesrat and three members in the Reichstag. Its ruling family, the House of Oldenburg, also came to rule in Denmark, Norway, Sweden, Greece and Russia. The heirs of a junior line of the Greek branch are, through Prince Philip, Duke of Edinburgh, in the line of succession to the thrones of the United Kingdom and the other Commonwealth realms after Queen Elizabeth II. As common for German houses, the ruling branch of Oldenburg, which ruled as Dukes and later Grand Dukes, holds the headship by primogeniture of the entire House of Holstein-Oldenburg with all its cadet branches.

Peter Friedrich Wilhelm, Duke of Oldenburg, (3 January 1754, Eutin Castle, Eutin – 2 July 1823, Schloss Plön, Plön.) Wilhelm succeeded his father, Frederick Augustus I, Duke of Oldenburg as the Duke of Oldenburg in 1785. Wilhelm's mother was Princess Ulrike Friederike Wilhelmine of Hesse-Kassel. Due to mental illness, Wilhelm was duke in name only, with his cousin Peter, Prince-Bishop of Lübeck, acting as regent throughout his entire reign. The title became a Grand Duke in 1815, but Wilhelm never used the elevated style. It was not used until 1829 by the son of Wilhelm's cousin and successor, Peter I
