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.).
Dzhokhar Dudayev
The Chechen-Ingush Republic split in two in June 1992, amidst the increasing Ossetian-Ingush conflict. After Chechnya had announced its initial declaration of sovereignty in 1991, its former entity Ingushetia opted to join the Russian Federation as a federal subject (Republic of Ingushetia). The remaining rump state of Ichkeria (Chechnya) declared full independence in 1993. That same year the Russian language stopped being taught in Chechen schools and it was also announced that the Chechen language would start to be written using the Latin alphabet (with some additional special Chechen characters) rather than Cyrillic in use since the 1930s. The state also began to print its own money and stamps. One of Dudayev's first decrees gave every man the right to bear arms.
