Since the Russian Republic's Caucasus Front dissolved, it did not have a true successor organization.
The Army of the North Caucasus, which was renamed 11th Army on October 3, 1918, constituted the main army of the Russian Republic in the area during the Russian Civil War. During the Russian Civil War the 11th Army fought against the White troops of General Anton Denikin's Volunteer Army in the western part of the North Caucasus. It was the main strength of the Caspian-Caucasian Army Group. In January 1919, the front of 200 miles held by the Red troops along the Caucasus foothills and South Russian steppes was cut into two by the White forces in the Northern Caucasus Operation, which resulted in the panic flight of the 11th Red Army. On 27 April 1920 the 11th Army took Baku and Azerbaijan Democratic Republic collapsed. The Bolsheviks then established the Azerbaijan Soviet Socialist Republic, as a Soviet republic in May 1920. This was the first country in the South Caucasus that the Bolsheviks seized control of. Taking advantage of its quarrels with neighboring Armenia, the 11th Army had little difficulty in initially sovietizing Azerbaijan. Although it soon was embroiled in a fierce anti-Soviet insurgency, the army remained poised to advance into the two remaining republics, Armenian and Georgia. For the time being, however, the authorities in Moscow ordered the army to stand down while negotiations between Russia and Armenia were being carried out. In that brief span the Red Army did aid Armenian communists fighting against the Armenian government in the Ijevan region of Armenia. In September-November 1920 Armenia and in February-March 1921, Georgia were invaded and brought under Bolshevik control. Having conquered the whole of Transcaucasia, the 11th Army was dissolved on May 29, 1921 and replaced by the Independent Caucasus Army.
Military decisions were supervised by the Army's Council of War. Its members were in 1921: Sergey Kirov, Valerian Kuybyshev, J.P. Butyagin, K.A. Mekhonoshin, Sokolov, J.I. Vesnik, Lukin, B.D. Mikhailov, Kvirkeliya, S.S. Eliava and P.I. Kushner. By 1921, the 11th Red Army is characterized by the modern French historian Marie Broxup as "a purely Russian army led by Russian commanders and Russian political cadres." In May 1921 the army lost its name and was integrated into the Caucasian Front, later part of the North Caucasus Military District.
