Derussification
Derussification (or derussianization) is a process or public policy in different states of the former Russian Empire and the Soviet Union or certain parts of them, aimed at restoring national identity of indigenous peoples: their language, culture and historical memory, lost due to Russification. The term may also refer to the marginalization of the Russian language, culture and other attributes of the Russian-speaking society through the promotion of other, usually autochthonous, languages and cultures.
