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.).
Ingush people
The Ingush (, , , pronounced ) are a Northeast Caucasian native ethnic group of the North Caucasus, mostly inhabiting their native Ingushetia, a federal republic of Russian Federation. The Ingush are predominantly Sunni Muslims and speak the Ingush language, a Northeast Caucasian language that is closely related to Chechen; the two form a dialect continuum. The Ingush and Chechen peoples are collectively known as the Nakh peoples, although the genetics of Ingush and the Chechen indicate a split about 13,000-17,000 Ybp.
