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.
