Don Host Oblast

Don Host Oblast was a province (oblast) of the Russian Empire which consisted of the territory of the Don Cossacks, coinciding approximately with present-day Rostov Oblast in Russia. Its administrative center was Cherkassk, and later Novocherkassk.

It comprised the areas where the Don Cossack Host settled in the Russian Empire. From 1786, the territory was officially named Don Host Land (Russian: Земля Войска Донского, romanized: Zemlya Voyska Donskogo), renamed Don Host Oblast in 1870.

During 1914, the oblast, with an area of 164,000 km², had about 3.9 million inhabitants. Of these, 55% (2.1 million) were Cossacks in possession of all the land; the remaining 45% of the population being townsfolk and agricultural guest labourers from other parts of Russia.

It was abolished in 1920; from the major part of it the Don Oblast of the RSFSR was created, which was incorporated into the North Caucasus Krai in 1924.
