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.
Chechnya
The Chechens and Ingush were allowed to return to their land after 1956 during de-Stalinization under Nikita Khrushchev when Chechen-Ingush Autonomous Soviet Socialist Republic was restored but both boundaries and ethnic composition of the territory significantly changed. There were many (predominantly Russian) migrants from other parts of the Soviet Union, who often settled in the abandoned family homes of Chechens and Ingushes. The republic lost its Prigorodny District which transferred to North Ossetian ASSR but gained predominantly Russian Naursky District and Shelkovskoy District that is considered the homeland for Terek Cossacks.
