1918 Central Powers occupation of Ukraine

The 1918 Central Powers occupation of Ukraine, also known as the Austro-German occupation of Ukraine or German and Austro-Hungarian occupation of Ukraine, in pro-Hetman sources also sometimes Control of Austro-German troops over the territory of Ukraine, was the military occupation of the territory of Ukraine by the Imperial German Army and the Austro-Hungarian Army during February–December 1918. It was carried out by the two main Central Powers of World War I, the German Empire and Austria-Hungary, in accordance with their 9 February 1918 Treaty of Brest-Litovsk with the Ukrainian People's Republic (UPR), that on 22 January 1918 had proclaimed Ukraine's independence from Bolshevik-controlled Soviet Russia.
