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
According to some Russian sources, from 1991 to 1994 tens of thousands of people of non-Chechen ethnicity (mostly Russians, Ukrainians, and Armenians) left the republic amidst reports of violence and discrimination against the non-Chechen population, as well as widespread lawlessness and ethnic cleansing under the government of Dzhokhar Dudayev.
