Kingdom of Prussia follows Swedish Pomerania
Subdivisions
The original core regions of the Kingdom of Prussia were the Margraviate of Brandenburg and the Duchy of Prussia which together formed Brandenburg-Prussia. A Further Pomeranian province had been held by Prussia since 1653. Combined with Swedish Pomerania, gained from Sweden in 1720 and 1815, this region formed the Province of Pomerania. Prussian gains in the Silesian Wars led to the formation of the Province of Silesia in 1740.
After the First Partition of Poland in 1772, the newly annexed Royal Prussia and Warmia became the Province of West Prussia, while the Duchy of Prussia (along with part of Warmia) became the Province of East Prussia. Other annexations along the Noteć (Netze) River became the Netze District. Following the second and third partitions (1793–1795), the new Prussian annexations became the Provinces of New Silesia, South Prussia, and New East Prussia, with the Netze District redivided between West and South Prussia. All the acquired Polish lands remained outside of the Holy Roman Empire, and the latter three provinces were disentangled from Prussia following the Treaties of Tilsit to be included in the Napoleonic Grand Duchy of Warsaw in 1806, and were ultimately lost to Congress Poland after the Congress of Vienna in 1815, except for the western part of South Prussia, which would form part of the Grand Duchy of Posen, the latter however also remained outside of German Confederation, the successor of the dissolved Holy Roman Empire, as did the Province of East Prussia and the Province of West Prussia.
Following the major western gains made by Prussia after the Vienna Congress, a total of ten provinces were established, each one subdivided further into smaller administrative regions known as Regierungsbezirke. The provinces were:
