Caucasus Military District

The Caucasus Military District (Russian: Кавказский военный округ, Kavkazskiy voenniy okrug) was a military formation of the Imperial Russian Army.

On the formation of the District, the Grand Duke Mikhail Nikolayevich (who had already been His Majesty's Viceroy in the Caucasus and Commander in Chief of the Caucasus Army since December 6, 1862) became its first Commander in Chief.

This army ceased to exist in April 1917 when it was reorganized by the new Russian Republic as the Caucasus Front, although this Front contained many of the same units and continued fighting in the same theater.

This Front in turn dissolved and formally ceased to exist in March 1918.

After a series of changes in 1866, 1868, 1878, 1881, 1883, 1898 and 1899, by 1914 the area of the District included seven provinces (Stavropol, Tiflis, Kutaisi, Elisavetpol, Baku, Erevan and the Black Sea) and five regions (Kuban, Terek, Dagestan, Kars and Batumi) - a total of 12 administrative divisions, of which three were in the north and nine in the Caucasus, these nine forming the Caucasian Viceroyalty of which the Commander in Chief of the district was viceroy.
