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.).
Self-determination
Under Dzhokhar Dudayev, Chechnya declared independence as the Chechen Republic of Ichkeria, using self-determination, Russia's history of bad treatment of Chechens, and a history of independence before invasion by Russia as main motives. Russia has restored control over Chechnya, but the separatist government functions still in exile, though it has been split into two entities: the Akhmed Zakayev-run secular Chechen Republic (based in Poland, the UK and the US), and the Islamic Caucasus Emirate.
