Description

The Eastern Front or Eastern Theater, of World War I,  was a theater of operations that encompassed at its greatest extent the entire frontier between Russia and Romania on one side and Austria-Hungary, Bulgaria, the Ottoman Empire, and Germany on the other. It ranged 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. The term contrasts with the Western Front, which was being fought in Belgium and France. Unlike the static warfare on the Western Front, the fighting on the geographically larger Eastern Front was more dynamic, often involving the flanking and encirclement of entire formations, and resulted in over 100,000 square miles of territory becoming occupied by a foreign power.
