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.).
Bohemian
The word "Bohemian" has never been widely used by the local Czech population. In Czech, the region since the early Middle Ages has been called "Čechy" but also, especially during the period of restoration/emancipation of the Czech language and nation, as "Čechie." Another term, stressing the importance of the state/nation, is "Království české" ("Czech Kingdom") in Czech, or "Böhmen" (Königreich) in German. Its mainly Czech-speaking inhabitants were called "Čechové" (in modern Czech "Češi").
