Fürstbistum Ermland
In 1808 during the Napoleonic Wars, East Prussia was divided into "Regierungsbezirke" Gumbinnen and Königsberg, comprising the western parts of the former Duchy of Prussia and the territory of the Prince-Bishopric of Warmia, annexed by Prussia in 1772. On November 1, 1905, the southern districts of the two regions were separated to create "Regierungsbezirk" Allenstein. According to the Prussian census of 1905, the reduced Regierungsbezirk Königsberg had a population of 893,427, of which around 96% were Germans and 4% were Lithuanians, who were mainly concentrated in the districts of Labiau and Memel.
