Reichsgau Wartheland

Posen was the southern of two Prussian administrative regions, or Regierungsbezirke (Polish: rejencja), of the Grand Duchy of Posen (1815–49) and its successor, the Province of Posen (1849–1918). The administrative region was bordered on the north by Regierungsbezirk Bromberg, to the west by the Province of Brandenburg, to the south by the Silesia Province, and to the east by Russian Congress Poland. The Posen region was inhabited mainly by Roman Catholic Poles, although it had a minority of mostly Protestant Germans. After World War I, most of the territory of this region was ceded to Poland.

The Battle of Poznań (Battle of Posen) during World War II in 1945 was a massive assault by the Soviet Union's Red Army that had as its objective the elimination of the Nazi German garrison in the stronghold city of Poznań (Posen) in occupied Poland. The defeat of the German garrison required almost an entire month of painstaking reduction of fortified positions, intense urban combat, and a final assault on the city's citadel by the Red Army, complete with medieval touches.

The Province of Posen (German: Provinz Posen, Polish: Prowincja Poznańska) was a province of the Kingdom of Prussia from 1848 to 1920. Posen was established in 1848 following the Greater Poland Uprising as a successor to the Grand Duchy of Posen, which in turn was annexed by Prussia in 1815 from Napoleon's Duchy of Warsaw. It became part of the German Empire in 1871. After World War I, Posen was briefly part of the Free State of Prussia within Weimar Germany, but was dissolved in 1920 when most of its territory was ceded to the Second Polish Republic by the Treaty of Versailles, and the remaining German territory was later re-organized into Posen-West Prussia in 1922. Posen (present-day Poznań, Poland) was the provincial capital.

The Grand Duchy of Posen (German: Großherzogtum Posen; Polish: Wielkie Księstwo Poznańskie) was part of the Kingdom of Prussia, created from territories annexed by Prussia after the Partitions of Poland, and formally established following the Napoleonic Wars in 1815. Per agreements derived at the Congress of Vienna it was to have some autonomy. However, in reality it was subordinated to Prussia and the proclaimed rights for Polish subjects were not fully implemented. The name was unofficially used afterward for denoting the territory, especially by Poles, and today is used by modern historians to refer to different political entities until 1918. Its capital was Posen (Polish: Poznań). The Grand Duchy was formally replaced by the Province of Posen in the Prussian constitution of December 5, 1848.

Poznań Voivodeship (Polish: Województwo Poznańskie) was a unit of administrative division and local government in Poland in the years 1919–1939, created after World War I from the Prussian-German province of Poznań (Province of Posen). The borders were changed in 1939: the city of Bydgoszcz passed to the Pomeranian Voivodeship, but some eastern areas were included (see Territorial changes of Polish Voivodeships on April 1, 1938). During World War II, it was occupied by Nazi Germany and annexed as Reichsgau Wartheland "(Reich province of the Land of the Warta River)".
