The Kabardians (Highland Adyghe: Къэбэрдей адыгэхэр; Lowland Adyghe: Къэбэртай адыгэхэр; Кабардинцы) or Kabardinians are one of the twelve major Circassian tribes, representing one of the twelve stars on the green-and-gold Circassian flag. They are also commonly known by the plural terms Kabardin, Kebertei, or Kabarday. Along with the Besleney tribe, they speak a distinctive dialect of the Adyghe language. Historically the Kabardians lived in Kabardia, a region of the north Caucasus. In modern times the Kabardians live mostly in the Russian republic of Kabardino-Balkaria, which partly corresponds to the historic region.
Despite the Soviet administrative divisions that placed Circassians under four different designations and political units, namely Adygeans (Adyghe in Adygea), Cherkessians (Adyghe in Karachay-Cherkessia), Kabardians (Adyghe in Kabardino-Balkaria), and Shapsugians (Adyghe in Krasnodar Krai), all four groups are essentially the same people (Adyghe). Furthermore, Cherkessians are mostly of the Kabardian and Besleney tribes.
The Kabardians are the largest Circassian (Adyghe) tribe in the world in general, and form the largest Circassian tribe in Russia, Turkey, Egypt, and in some other countries in the region. Kabardians numbered around 520,000 in Kabardino-Balkaria, Russia. and about 50,000 in Karachay-Cherkessia, Russia. In Turkey, where more than 1 million of them live, they are concentrated on the Uzunyayla plateau of Kayseri Province and around (Central Turkey), though there are Kabardian villages in Balıkesir, Düzce, Eskişehir (Northwest Turkey), Çorum, Samsun, and Tokat (Black Sea region), amongst many others. Significant populations of Kabardians also live in Jordan;
and there are communities in the United States. However, in Israel and Jordan, the Shapsug and Abzakh tribes respectively are the largest.
Religions historically practiced by Kabardians include the native Adyghe Xabze faith, Christianity and Islam. The majority of Kabardians had converted to Islam by the early 19th century.
