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.).
Chechen Kurds
Chechen Kurds or Kurdified Chechens refer to the ethnic Chechens who went through a process of kurdification after fleeing to Kurdistan during and after the Russian conquest of the Caucasus in the 1860s. Today, these Chechens are being perceived as being ethnic Kurds of the "Chechen tribe" and "Lezgî tribe".
