History

Early history

Before the whole area was conquered by Cimmerian, Scythian, and Sarmatian invaders, the Zygii (Proto-Adyghe) people lived in Lesser Abkhazia under the Kingdom of Pontus, then the Roman Empire's influence in antiquity. From the 6th to the 11th centuries, the area successively belonged to the Georgian kingdoms of Lazica and Abkhazia, who built a dozen churches within the city boundaries, the later was unified under the single Georgian monarchy in 11th-century, forming one of the Saeristavo, known as Tskhumi extending its possessions up to Nicopsis. The Christian settlements along the coast were destroyed by the invading Alans, Khazars, Mongols, and other nomadic empires whose control of the region was slight. The northern wall of an 11th-century Byzantine basilica still stands in the Loo Microdistrict.

Between the 13th and 15th centuries, the Republic of Genoa had the monopoly of the trade on the shores of the Black Sea, and established colonies and trading posts in the region of the present-day Sochi, the large ones were Layso and Costa.

From the 14th to the 19th centuries, the region was dominated by the Abkhaz, Ubykh, and Adyghe tribes, the current location of the city of Sochi known as Ubykhia was part of historical Circassia and was controlled by the native people of the local mountaineer clans of the north-west Caucasus, nominally under the sovereignty of the Ottoman Empire, which was their principal trading partner in the Muslim world.

Russian Empire

The coastline was ceded to Russia in 1829 as a result of the Caucasian War and the Russo-Turkish War, 1828–1829; however, the Circassians did not accept the Russian control over Circassia and kept resisting the newly established Russian outposts along the Circassian coast. The provision of weapons and ammunition from abroad to the Circassians caused a diplomatic conflict between the Russian Empire and the British Empire that occurred in 1836 over the mission of the Vixen.

The Russians had no detailed knowledge of the area until Baron Feodor Tornau investigated the coastal route from Gelendzhik to Gagra, and across the mountains to Kabarda, in the 1830s. In 1838, the fort of Alexandria renamed Navaginsky a year later, was founded at the mouth of the Sochi River as part of the Black Sea coastal line, a chain of seventeen fortifications set up to protect the area from recurring Circassian resistance. At the outbreak of the Crimean War, the garrison was evacuated from Navaginsky in order to prevent its capture by the Turks, who effected a landing on Cape Adler soon after.

The last battle of the Caucasian War took place at the Godlikh river on March 18, 1864, O.S., where the Ubykhs were defeated by the Dakhovsky regiment of the Russian Army. On March 25, 1864, the Dakhovsky fort was established on the site of the Navaginsky fort. The end of the Caucasian War was proclaimed at Kbaade tract (modern Krasnaya Polyana) on June 2 (21 May O.S.), 1864, by the manifesto of Emperor Alexander II read aloud by Grand Duke Michael Nikolaevich of Russia.

After the end of the Caucasian War (during the period of 1864–1870) almost all Ubykhs and a major part of the Shapsugs, who lived on the territory of modern Sochi, were either killed in the Circassian Genocide or expelled to the Ottoman Empire. Starting in 1866 the coast was actively colonized by Russians, Armenians, Ukrainians, Belorussians, Greeks, Germans, Georgians, and other people from inner Russia.

In 1874–1891, the first Russian Orthodox church, St. Michael's Church, was constructed, and the Dakhovsky settlement was renamed Dakhovsky Posad on April 13, 1874 (O.S.). In February 1890, the Sochi Lighthouse was constructed. In 1896, the Dakhovsky Posad was renamed Sochi Posad (after the name of the local river) and incorporated into the newly formed Black Sea Governorate. In 1900–1910, Sochi burgeoned into a sea resort. The first resort, "Kavkazskaya Riviera", opened on June 14, 1909 (O.S.). Sochi was granted town status in 1917.

Soviet time

During the Russian Civil War, the littoral area saw sporadic armed clashes involving the Red Army, White movement forces, and the Democratic Republic of Georgia. As a result of the war, Sochi has become Russian territory. In 1923, Sochi acquired one of its most distinctive features, a railway that runs from Tuapse to Georgia within a kilometer or two of the coastline. Although this branch of the Northern Caucasus Railway may appear somewhat incongruous in the setting of beaches and sanatoriums, it is still operational and vital to the region's transportation infrastructure.

Sochi was established as a fashionable resort area under Joseph Stalin, who had his favorite dacha built in the city. Stalin's study, complete with a wax statue of the leader, is now open to the public. During Stalin's reign, the coast became dotted with imposing Neoclassical buildings, exemplified by the opulent Rodina and Ordzhonikidze sanatoriums. The centerpiece of this early period is Shchusev's Constructivist Institute of Rheumatology (1927–1931). The area was continuously developed until the demise of the Soviet Union.

Modern Russia

Following Russia's loss of the traditionally popular resorts of the Crimean Peninsula (transferred from the Russian SFSR to the Ukrainian SSR in 1954 by Nikita Khrushchev), Sochi emerged as the unofficial summer capital of the country. In 1961, Soviet officials decided to expand the city limits by forming a Greater Sochi which extended for 140 kilometers from the southern parts of Tuapse to Adler. In July 2005, Russia submitted a successful bid for hosting the 2014 Winter Olympics in the city, spending around $51 billion in the process. Additionally, Sochi has also served as the location for the signing of many treaties, especially those between Georgia and the breakaway regions of Abkhazia and South Ossetia governing authorities.

In 2019, an area in the Imereti Lowlands was divided from Adlersky City District and formed as a separate urban-type settlement named Sirius. It was later designated as a federal territory.
