Concept note-2: -The eastern front encompassed the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria and Germany on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south.
Concept note-3: -The principal belligerents were Russia and Romania (of the Allied and Associated Powers) versus the Central Powers countries of Germany, Austria-Hungary, and Bulgaria. The Eastern Front, which stretched from the Baltic Sea in the north to the Black Sea in the south, was more than twice as long as the Western Front.
Concept note-4: -It stretched from the Baltic Sea in the north to the Black Sea in the south, involved 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.
