Generalbezirk Estland in the context of "Reichskommissariat Ostland"

The Reichskommissariat Ostland (RKO; lit. 'Reich Commissariat of Eastland') was an administrative entity of the Reich Ministry for the Occupied Eastern Territories of Nazi Germany from 1941 to 1945. It served as the German civilian occupation regime in Lithuania, Latvia, Estonia, and the western part of the Byelorussian SSR during the Eastern Front of World War II.

Ostland was established after the success of the Wehrmacht's Baltic operation and an initial period of military administration by Army Group North Rear Area based on the equivalent Reichskommissariat Baltenland in German planning documents. It was divided into Generalbezirk Estland (Estonia), Generalbezirk Lettland (Latvia), Generalbezirk Litauen (Lithuania), and Generalbezirk Weißruthenien (Belarus) each with its own Nazi collaborationist government and Auxiliary Police under the control of a German Generalkommissar. Hinrich Lohse served as the Reichskommissar from 1941 to 1944 and Erich Koch from 1944 to 1945.
