Abkhazia (Abkhaz: Аҧсны́ Apsny [apʰsˈnɨ]; Georgian: აფხაზეთი Apkhazeti; Russian: Абхазия Abkhaziya) is a disputed territory on the eastern coast of the Black Sea and the south-western flank of the Caucasus.
Abkhazia considers itself an independent state, called the Republic of Abkhazia or Apsny. This status is recognised by Russia, Nicaragua, Venezuela, Nauru, Tuvalu and also by the partially recognised state of South Ossetia, and the unrecognized Transnistria and Nagorno-Karabakh.
The Georgian government and the majority of the world's governments consider Abkhazia a part of Georgia's territory. Under Georgia's official designation it is an autonomous republic, called the Autonomous Republic of Abkhazia, whose government sits in exile in Tbilisi.
