Although related, Abazgi and Circassian are mutually unintelligible. Abazgi is spoken by Abkhazians and the Abazins. The Abkhazians lived on the coast between the Circassians and the Georgians, were organized as the Principality of Abkhazia and were involved with the Georgians to some degree. The Abazins or Abaza, their relatives, lived north of the mountains and were involved with Circassia proper. They extended from the mountain crest northeast onto the steppe and partially separated the Kabardians from the rest. Sadz were either northern Abkhazian or eastern Abaza, depending on the source.
