It ceased to exist on May 17, 1935 when it was redesignated as the Transcaucasian Military District in connection with the overall reorganization of the Red Army.
The army consisted of 6 territorial divisions, an air force, and some reserve troops.
In subsequent operations along the Caspian coast 11th Army troops, overcoming stiff resistance, in early 1920 liberated the towns of Petrovsk, Derbent, and finally Baku, facilitating the transfer of the richest oil region into the hands of the workers.
Subsequent fighting by 11th Army led to the downfall of the Muslim government of Azerbaijan and the establishment there of the Soviet Republic.
Instead of 8 military districts and 2 separate armies, 13 military districts were created: Moscow, Leningrad, Belarus, Kiev, Kharkov, North Caucasus, Transcaucasia, Central Asia, Volga, Urals, Siberia, Transbaikalia, and Far East.
