The Battle of Galicia, also known as the Great Battle of Galicia, was a major battle between Russia and Austria-Hungary during the early stages of World War I in 1914. In the course of the battle, the Austro-Hungarian armies were severely defeated in several encounters and forced out of Galicia, while the Russians captured Lemberg and, for approximately nine months, ruled Eastern Galicia until their defeat at Gorlice and Tarnów. The Battle of Galicia showed weaknesses of the Austro-Hungarian Army during that period and at the same time was one of the formidable victories of the Imperial Russian Army in the war.
