The Chechens (ˈtʃɛtʃɛnz,_tʃəˈtʃɛnz; Нохчий, Noxçiy, Old Chechen: Нахчой, Naxçoy), historically also known as Kisti and Durdzuks, are a Northeast Caucasian ethnic group of the Nakh peoples native to the North Caucasus. They are the largest ethnic group of the North Caucasus and refer to themselves as Nokhchiy (pronounced [no̞xtʃʼiː]; singular Nokhchi, Nokhcho, Nakhchuo or Nakhtche). The vast majority of Chechens today are Muslims and live in Chechnya, a republic of Russia.
The North Caucasus has been invaded numerous times throughout history. Its isolated terrain and the strategic value outsiders have placed on the areas settled by Chechens has contributed much to the Chechen community ethos and helped shape its national character.
Chechen society has traditionally been egalitarian and organized around many autonomous local clans, called teips.
According to popular tradition, the Russian term Chechency (Чеченцы) comes from central Chechnya, which had several important villages and towns named after the word Chechen. These places include Chechan, Nana-Checha ("Mother Checha") and Yokkh Chechen ("Greater Chechena"). The name Chechen occurs in Russian sources in the late 16th century as "Chachana", which is mentioned as a land owned by the Chechen Prince Shikh Murza. The etymology is of Nakh origin and originates from the word Che ("inside") attached to the suffix - cha/chan, which altogether can be translated as "inside territory". The villages and towns named Chechan were always situated in the Chechan-are ("Chechen flatlands or plains") located in today's central Chechnya.
Although Chechan (Chechen) was a term used by Chechens to denote a certain geographic area (central Chechnya), Chechens called themselves Nakhchiy (highland dialects) or Nokhchiy (lowland dialects). The oldest mention of Nakhchiy occurred in 1310 by the Georgian Patriarch Cyril Donauri, who mentions the 'People of Nakhche' among Tushetians, Avars and many other Northeast Caucasian nations.
