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.
Teip
Historically, if non-Chechen minorities living in Chechen lands wanted to take part in the political processes of the Chechen nation, and integrate into it, they would request admittance as an ethnic teip. They would continue, for a time, to speak their other languages, but also learned Chechen. Due to the encouragement of teip exogamy, as the generations passed, they would come to be heavily intermarried into the Chechen nation and as a result, be slowly Chechenized culturally and linguistically. The level of Chechenization varies between these foreign-origin teips, with some well-preserving their cultural traits and others not. They are nonetheless known as impure teips (not in a derogatory sense), for their foreign origin. Their loyalty to the nation is not any more in question than a Chechen-origin teip.
