Adyghe people
The "Encyclopaedia Islamica" adds: "The Cherkess, the Kabardians and the western Adyghe people share a common language, which is spoken by the north-western Caucasian people, and belongs to the family known as Abkhazian-Adyghe". In Persian sources, "Charkas/Cherkes" is used to refer to the "actual" Circassians of the northwest Caucasus, and in some occasions as a general designation for Caucasians who live beyond Derbent (Darband).
