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.
Chechen Kurds
Chechen Kurds or Kurdified Chechens refer to the ethnic Chechens who went through a process of kurdification after fleeing to Kurdistan during and after the Russian conquest of the Caucasus in the 1860s. Today, these Chechens are being perceived as being ethnic Kurds of the "Chechen tribe" and "Lezgî tribe".
