Kingdom of Prussia

The area of the Darkehmen district belonged to the former Insterburg district since East Prussia was divided into districts in 1752.^[1][2] As part of the Prussian administrative reforms, a comprehensive district reform was done in all of East Prussia, as the districts established in 1752 had proven to be inexpedient and too large. On 1 September 1818 the new Darkehmen district was formed in Regierungsbezirk Gumbinnen from parts of the old Insterburg district. This included the parishes of Ballethen, Darkehmen, Dombrowken, Groß Karpowen, Kleszowen, Rogahlen, Szabienen, Trempen and Wilhelmsberg. The district office was in Darkehmen.

Germany

Since 1871, the district belonged to the German Empire. On 21 July 1875 the rural community of Grünheide was transferred from the Darkehmen district to the Gumbinnen district. On 10 August 1876 the rural communities Alt Gurren and Neu Gurren and the Gurren manor district were transferred from the Darkehmen district to the Angerburg district, while the Broszeitschen manor district moved from the Angerburg district to the Darkehmen district.

On 30 September 1928 a regional reform took place in the Darkehmen district as in the rest of Prussia, in which all inhabited manor districts were dissolved and assigned to neighboring rural communities. On 7 September 1938 the district and its capital were renamed Angerapp.

Under Polish and Soviet administration

With the Soviet advance into East Prussia which began in January 1945, the district was gradually occupied by the Red Army. The entire district was initially placed under the Polish civil administration. The district and its capital were given the name Darkiejmy, the Polish name for Darkehmen.

Later in 1945, the Soviet Union moved the border significantly to the south, so that a large part of the district, including the town of Darkehmen, which was renamed Ozyorsk came under Soviet administration.^[3]

Only a small part of the district south of the demarcation line remained under Polish administration and was attached to the Węgorzewo County. The remaining German population was subsequently expelled by the local Polish authorities.
