Central Powers victory

The Eastern Front or Eastern Theater of World War I (Russian: Восточный фронт, Vostochnıy front, sometimes called the "Second Fatherland War" or "Second Patriotic War" (Russian: Вторая Отечественная война, Vtoraya Otechestvennaya voyna) in Russian sources) was a theatre of operations that encompassed at its greatest extent the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria, the Ottoman Empire and the German Empire on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, included most of Eastern Europe and stretched deep into Central Europe as well. The term contrasts with "Western Front", which was being fought in Belgium and France.

In the opening months of the war, the Imperial Russian Army attempted an invasion of eastern Prussia in the northwestern theater, only to be beaten back by the Germans after some initial success. At the same time, in the south, they successfully invaded Galicia, defeating the Austro-Hungarian forces there. In Russian Poland, the Germans failed to take Warsaw. But by 1915, the German and Austro-Hungarian armies were on the advance, dealing the Russians heavy casualties in Galicia and in Poland, forcing it to retreat. Grand Duke Nicholas was sacked from his position as the commander-in-chief and replaced by the Tsar himself. Several offensives against the Germans in 1916 failed, including Lake Naroch Offensive and the Baranovichi Offensive. However, General Aleksei Brusilov oversaw a highly successful operation against Austria-Hungary that became known as the Brusilov Offensive, which saw the Russian Army make large gains.
