Grand Duchy of Posen
The Grand Duchy of Posen (; ) 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. On 9 February 1849, the Prussian administration renamed the grand duchy to the Province of Posen. Its former 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 (). History Background Originally part of the Kingdom of Poland, this area largely coincided with Greater Poland. The eastern portions of the territory were taken by the Kingdom of Prussia during the Partitions of Poland; during the first partition (1772), Prussia took just the Netze District, the portion along the Noteć () river. Prussia added the remainder during the second partition in 1793. Prussia briefly lost control during the Kościuszko Uprising in 1794. It was initially administered as the province of South Prussia. The Poles were the primary ally of Napoleon Bonaparte in Central Europe, participating in the Greater Poland Uprising of 1806 and supplying troops for his campaigns. After the defeat of Prussia by Napoleonic France, the Duchy of Warsaw was created by the Treaty of Tilsit in 1807. 1815–1830 According to the Congress of Vienna, put into action after the fall of Napoleon in 1815, parts of the Prussian territory partitioned from Poland were passed on to Russia. From the remainder the Grand Duchy of Posen was to be created, that was to be a nominally autonomous province under Hohenzollern rule with the rights of "free development of Polish nation, culture and language", and was outside the German Confederation. Originally the Grand Duchy was to include Chełmno and Toruń. Prussia however disregarded this promise from Congress of Vienna. At this time the city of Poznań was the administrative centre and the seat of the Statthalter "Prince Antoni Henryk Radziwiłł of Poznań". In reality the actual administrative power over the region was awarded by Prussia to provincial upper-president Joseph Zerboni di Sposetti, who was a Prussian of German ethnicity. At the beginning of the Prussian takeover of Polish territories, the discrimination and repression of Poles consisted of reducing their access to education and the judicial system. Prussian officials identified Germanisation as the progress of higher culture over a lower one. As a result, the local administration discriminated against Poles. After 1824 attempts to Germanise the school system were hastened and the government refused to establish a Polish university in Poznań. Polish politicians issued protests against Prussian policies and a secret, patriotic Polish organisation was founded called Towarzystwo Kosynierów (Society of Scythemen). Resistance activity of Poles resulted in reaction from Berlin, where a trial was held in connection to links between Poles from the
