Chechens
Chechens (; '; Old Chechen: Нахчой "Naxçoy") are a Northeast Caucasian ethnic group of the Nakh peoples originating in the North Caucasus region of Eastern Europe. They refer to themselves as Vainakhs (which means "our people" in Chechen) or Nokhchiy (pronounced ; singular Nokhchi, Nakhchuo or Nakhtche). Chechen and Ingush peoples are collectively known as the Vainakh. The majority of Chechens today live in the Chechen Republic, a subdivision of the Russian Federation.
Chechens
Nakh peoples such as Chechens are thought to either be descended from original settlers of the Caucasus (North and/or South) or supposedly Nakh-speaking ethnic minorities in the north-eastern regions of the ancient state of Urartu (whose people also spoke a language that was possibly related to the Nakh languages). The two theories are not mutually incompatible, and there has been much evidence that seems to link both of the two together (either by dual origins or the "return" theory, in which the Nakh peoples originally lived in the Caucasus and then returned). Chechen genetics show a high level of genetic diversity (see section below).
