the Russian Civil War. A short-lived Bolshevik government was suppressed in May 1918 and Sukhumi was incorporated into the Democratic Republic of Georgia as a residence of the autonomous People's Council of Abkhazia and the headquarters of the Georgian governor-general. The Red Army and the local revolutionaries took the city from the Georgian forces on 4 March 1921, and declared Soviet rule. Sukhumi functioned as the capital of the "Union treaty" Abkhaz Soviet Socialist Republic associated with the Georgian SSR from 1921 until 1931, when it became the capital of the Abkhazian Autonomous Soviet Socialist Republic within the Georgian SSR. By 1989, Sukhumi had 120,000 inhabitants and was one of the most prosperous cities of Georgia. Many holiday dachas for Soviet leaders were situated there. Beginning with the 1989 riots, Sukhumi was a centre of the Georgian-Abkhaz conflict, and the city was severely damaged during the 1992–1993 War. During the war, the city and its environs suffered almost daily air strikes and artillery shelling, with heavy civilian casualties. On 27 September 1993 the battle for Sukhumi was concluded by a full-scale campaign of ethnic cleansing against its majority Georgian population (see Sukhumi Massacre), including members of the pro-Georgian Abkhazian government (Zhiuli Shartava, Raul Eshba and others) and mayor of Sukhumi Guram Gabiskiria. Although the city has been relatively peaceful and partially rebuilt, it is still suffering the after-effects of the war, and it has not regained its earlier ethnic diversity. A relatively large infrastructure reconstruction program was launched in 2019–2020 focusing on the renovation of the waterfront, rebuilding city roads and cleaning city parks. Its population in 2017 was 65,716, compared to about 120,000 in 1989. During summer holidays season its population usually doubles and triples with a large inflow of international tourists. In 2021, there was unrest in the city. Population Demographics Historic population figures for Sukhumi, split out by ethnicity, based on population censuses: The Abkhazians were deemed "guilty" from 1877, but officially it was by an order of the tsar of 31 May 1880 that their "guilt" was recognised. Abkhazians were forbidden to settle near the coast (except for the upper classes), or live in Sukhum. The devastated central part of Abkhazia between the rivers Psyrtskha and Kodor became a colonised land-fund of the imperial administration. There was established here a kind of buffer-zone between the Gudauta and Ochamchira Abkhazians. Abkhazians had no right to settle in
