Oldenburg Land in the context of Boßeln

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, that consisted of three widely separated territories: Oldenburg, Eutin and Birkenfeld. It ranked tenth among the German states, 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, Russia and United Kingdom.

The Oldenburg Münsterland, otherwise called Oldenburger Münsterland or Oldenburgisches Münsterland, is a region in Lower Saxony, Germany and the administrative area that comprises the federal districts of Cloppenburg and Vechta. It forms the southern part of the historical region of Oldenburg Land, so it is also called Südoldenburg. The inhabitants of the region accordingly call themselves Südoldenburger, with the denominative Oldenburger Münsterländer being rather uncommon.
