Gumbinnen (region)

Regierungsbezirk Gumbinnen was a Regierungsbezirk, or government region, of the Prussian province of East Prussia from 1808 until 1945. The regional capital was Gumbinnen (Gusev).

History
In 1808 during the Napoleonic Wars, East Prussia was divided into the Regierungsbezirke of Gumbinnen, comprising the eastern parts of the former Duchy of Prussia, and Königsberg. On November 1, 1905, the southern districts of the two regions were separated to create Regierungsbezirk Allenstein. The districts of Johannisburg, Lötzen, Lyck and Sensburg were transferred from Regierungsbezirk Gumbinnen to Regierungsbezirk Allenstein. Regierungsbezirk Gumbinnen was dissolved in 1945 when East Prussia was partitioned between Poland and the Soviet Union after World War II according to the resolutions at the Potsdam Conference.
