Sukhumi okrug

The Sukhumi or Sukhum okrug was a special administrative district (okrug) in the Caucasus Viceroyalty of the Russian Empire, part of the Kutaisi Governorate from 1883 until 1905. The administrative center of the district was the Black Sea port city of Sukhum (present-day Sukhumi). The okrug bordered the Kutaisi Governorate to the southwest, the Kuban Oblast to the north and the Black Sea Governorate to the northwest and in terms of its area corresponded to most of contemporary Abkhazia. During 1905–1917, the Sukhumi okrug was one of the smallest independent (not part of any province or region) administrative units of the Russian Empire, second to the Zakatal okrug.

History
In the 19th century, the territory of the Sukhumi okrug, some 6942 verst2 containing 79,195 inhabitants, consisted of the Principality of Abkhazia (abolished in 1864) and the communities of Tsebelda, Samurzakan, and Pskhu community. In 1864–1866, the military district of Sukhumi was made up of the okrugs of Abkhaz, Bzyb, and Abzhua and pristavstvos of Tsebelda and Samurzakan. In 1883, the district was transformed into an okrug and incorporated into the Kutaisi Governorate. In 1905, the Sukhumi okrug was separated from the Kutaisi Governorate to be directly administered by the Viceroy of the Caucasus.

In April–May 1918, Georgian forces of the Transcaucasian Democratic Federative Republic prevented Soviet forces from taking the district. In June 1918, as a result of an agreement between the authorities of the Georgian Democratic Republic and the Abkhaz People's Council, the Georgian army occupied the district as well as the adjacent Sochi and Tuapse okrugs—the Georgian government aimed to "present the Volunteer Army with a fait accompli", using historical justifications for incorporating these districts.

As result of attempts by Anton Denikin to conquer the district in 1919 during the Sochi conflict, a neutralised bufferzone was imposed north of the district in the Sochinsky okrug, between the Mekhadiri and Psou rivers. According to the Treaty of Moscow (1920), the Georgia–Russia border in Abkhazia was "traced along the Psou" rather than the Bzyb (further south) which had been the boundary of the Sukhumi okrug. The 1921 constitution of Georgia guaranteed Abkhazia the autonomy for managing its internal affairs. The constitution was proclaimed after the Red Army invasion of Georgia in February 1921; the nature of the promised autonomy was never determined.

The subcounties (uchastoks) of the Sukhumi okrug in 1912 were as follows:
