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.
Čačak
Ethnically, the city is largely inhabited by Serbs (95.3%), followed by Roma, Montenegrins and other ethnic groups. The ethnic composition of the city:
From 1885, when Čačak had a population of only 3,000, a small groups of Armenians began settling in town. They mostly originated from the villages of Kemah and Nerkin Bagarij (or Pakarish), near Erzincan in Ottoman Empire, fleeing the forcible draft into the Ottoman army and the general oppression against the Armenians in the empire. The first Armenian in Čačak was Arut Nigosjan, who worked as "tahmiščija", a coffee roaster/grinder. He was followed by the families of Sarkisjan (later changed name to Sarkisović), Nikolić, Sukjasjan, Bricki, Berberjan and Lazarjan, with most of them working in the coffee business. Lazarjan family was the best known Armenian family in Čačak as they expanded their business from just coffee to the grocery stores and were among the founders of the local Red Cross organization. New Communist authorities after World War II, in the massive process of nationalization, confiscated the Armenian businesses in 1948 so some of them emigrated abroad. In time, the Armenians began naming their children with Serbian names and blended with the rest of the population. The book, "Jermeni u Čačku 1885-1950" ("Armenians in Čačak 1885-1950") was published by Marijana Matović in 2018.
