Эстляндская губерния
After the Russian Revolution, German troops started advancing from Courland, and by the end of February 1918 the territories of the former Russian Governorate of Livonia and Autonomous Governorate of Estonia that had declared independence were also occupied and fell under the German military administration. With the Treaty of Brest-Litovsk on 3 March 1918 Bolshevist Russia accepted the loss of the Courland Governorate and by agreements concluded in Berlin on 27 August 1918 the Autonomous Governorate of Estonia and the Governorate of Livonia were severed from Russia.
