Chechens
In 1989, 73.4% spoke Russian, though this figure has declined due to the wars for a large number of reasons (including the lack of proper education, the refusal to learn the language, and the mass dispersal of the Chechen diaspora due to the war). Chechens in the diaspora often speak the language of the country they live in (English, German, Arabic, Polish, Georgian, etc.).
Koban culture
Amjad Jaimoukha argues that while all these cultures probably were made by people included among the genetic ancestors of the Northern Caucasian Nakh (i.e. Chechens and Ingush), it was either the Koban or Kharachoi culture that was the first culture made by the cultural and linguistic ancestors of the Chechens (meaning the Chechens first arrived in their homeland 3000–4000 years ago). Johanna Nichols has written that "There is fairly seamless archeological continuity for the last 8000 years or more in central Daghestan, suggesting that the Nakh-Daghestanian language family is long indigenous."
