Sukhumi or Sukhum (, ), also known by its Georgian name Sokhumi (, ) or Abkhaz name Aqwa (, Aqwa), is a city in a wide bay on the Black Sea's eastern coast. It is both the capital and largest city of the Republic of Abkhazia, which has controlled it since the Abkhazia war in 1992–93. However, internationally Abkhazia is considered part of Georgia. The city, which has an airport, is a port, major rail junction and a holiday resort because of its beaches, sanatoriums, mineral-water spas and semitropical climate. It is also a member of the International Black Sea Club. Sukhumi's history can be traced to the 6th century BC, when it was settled by Greeks, who named it Dioscurias. During this time and the subsequent Roman period, much of the city disappeared under the Black Sea. The city was named Tskhumi when it became part of the Kingdom of Abkhazia and then the Kingdom of Georgia. Contested by local princes, it became part of the Ottoman Empire in the 1570s, where it remained until it was conquered by the Russian Empire in 1810. After a period of conflict during the Russian Civil War, it became part of the independent Georgia, which included Abkhazia, in 1918. In 1921, the Democratic Republic of Georgia was occupied by Soviet Bolshevik forces from Russia. Within the Soviet Union, it was regarded as a holiday resort. As the Soviet Union broke up in the early 1990s, the city suffered significant damage during the Abkhaz–Georgian conflict. The present-day population of 60,000 is only half of the population living there toward the end of Soviet rule. Toponym In Georgian, the city is known as Sokhumi (სოხუმი), amongst Samurzakans in Megrelian the city is sometimes referred to as Aqujikha (აყუჯიხა), and in Russian as Сухум (Sukhum) or Сухуми (Sukhumi). The toponym Sokhumi derives from the Georgian word Tskhomi/Tskhumi (ცხომი/ცხუმი), which in turn is supposed to be derived from Svan tskhum (ცხუმ) meaning "hornbeam tree". In Abkhaz, the city is known as Aqwa (Аҟәа) which is believed to derive from a-qwara (а-ҟәара), meaning "stony seashore". According to Abkhaz tradition Aqwa (Аҟәа) signifies water. Medieval Georgian sources knew the town as Tskhumi (ცხუმი). Later, under Ottoman control, the town was known in Turkish as Suhum-Kale, which was derived from the earlier Georgian form Tskhumi or read to mean "Tskhumi fortress".
