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.
Mountain Jews
In Chechnya, Mountain Jews partially assimilated into Chechen society by forming a Jewish teip, the Zhugtii while three other teips, the Shuonoi, Ziloi and Chartoi have also been theorized to have Jewish relations. In Chechen society, ethnic minorities residing in areas demographically dominated by Chechens have the option of forming a teip in order to properly participate in the developments of Chechen society such as making alliances and gaining representation in the "Mekhk Khell", a supreme ethnonational council that is occasionally compared to a parliament. Teips of minority-origin have also been made by ethnic Poles, Germans, Georgians, Kumyks, Russians, Kalmyks, Circassians, Andis, Avars, Dargins, Laks, Persians, Arabs, Ukrainians and Nogais, with the German teip having been formed as recently as the 1940s when Germans in Siberian exile living among Chechens assimilated.
