Abkhazians or Abkhaz (Abkhaz: Аҧсуа, Apswa; Georgian: აფხაზები [ɑpʰxɑzɛbi]) are a Caucasian ethnic group, mainly living in Abkhazia, a disputed region on the Black Sea coast. A large Abkhaz diaspora population resides in Turkey, the origins of which lie in the emigration from the Caucasus in the late 19th century known as muhajirism. Many Abkhaz also live in other parts of the former Soviet Union, particularly in Russia and Ukraine.
