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.
Grozny
Grozny became the administrative center of Grozny Oblast of the Russian SFSR, and the city at the time was again wholly Russian. In 1957, the Chechen-Ingush ASSR was restored, and the Chechens were allowed to return. The return of the Chechens to Grozny, which had been lacking of Nakh for thirteen years, would cause massive disruptions to the social, economic and political systems of what had been a Russian city for the period until their return. This caused a self-feeding cycle of ethnic conflict between the two groups, both believing the other's presence in the city was illegitimate. Once again migration of non-Russians into Grozny continued whilst the ethnic Russian population, in turn, moved to other parts of the USSR, notably the Baltic states, after the inter-ethnic conflict broke briefly out in 1958.
According to sociologist Georgy Derluguyan, the Checheno-Ingush Republic's economy was divided into two spheres—much like French settler-ruled Algeria—and the Russian sphere had all the jobs with higher salaries, while non-Russians were systematically kept out of all government positions. Russians (as well as Ukrainians and Armenians) worked in education, health, oil, machinery, and social services. Non-Russians (excluding Ukrainians and Armenians) worked in agriculture, construction, a long host of undesirable jobs, as well as the so-called "informal sector" (i.e., illegal, due to the mass discrimination in the legal sector).
