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.
Early derussification processes manifested themselves in the newly independent states that emerged after the collapse of the Russian Empire in 1917, such as Poland, Finland, Georgia, Estonia, Latvia, and Lithuania.
The share of Slavs in the region, which at that time was 10.6% of the population (including 7.7% of Russians proper), dropped to a few thousand Spiritual Christians from Russia, most of whom returned to the Soviet Union in the mid-1920s and mid-1960s.
In the period between 1945 and 1969, the derussification of Harbin ended, which at the peak of White emigration during the 1920s had an almost 300,000 Russian-speaking population in Northeast China.
The term korenizatsiia went out of use in the latter half of the 1930s, replaced by more bureaucratic expressions, such as "selection and placement of national cadres" (подбор и расстановка национальных кадров).
"[5] After the Sino-Soviet split, the Chinese Ministry of Public Security and the State Bureau of Surveying and Mapping in 1963 issued the document "Notice on Requesting Investigation and Research on Issues Existing in Russian Place Names and Proposing Handling Opinions", demanded Heilongjiang Province to derussify place names within its jurisdiction.
[6] In most of the Central Asian and Transcaucasian republics of the former Soviet Union, the share and size of the Russian population fell particularly rapidly due to mass emigration, natural decline, and a prolonged population explosion among indigenous peoples who began to increase their presence in Russia as migrant workers.
Since the collapse of the Soviet Union, the number of countries officially using the Cyrillic script shrank, which can also be considered a sign of derussification.
The Director of the Institute of Linguistics, Erden Kazybek, said that each letter of the alphabet will mean one sound and will not include additional graphic characters.
[12] On February 26, 2018, during a meeting with the Minister of Information and Communications, Dauren Abayev, President of Kazakhstan Nursultan Nazarbayev ordered to translate the activities of the state authorities exclusively into the Kazakh language.
[15] Russian is still in use but not as important as it was in the Soviet era, since it has no special status in the country and its usage as mother tongue has been declining for some time.
[24] As of April 8, 2022, according to a poll by the sociological group Rating, 76% of Ukrainians support the initiative to rename streets and other objects whose names are associated with Russia or the Soviet Union.
[27] This law prohibits toponymy that symbolizes or glorifies Russia, individuals who carried out aggression against Ukraine (or another country), as well as totalitarian policies and practices related to the Russian Empire and the Soviet Union, including Ukrainians living in Russian-occupied territories.
[27] The Baltic states (Lithuania, Latvia and Estonia) have undergone derussification since regaining independence from the Soviet Union in 1991.
One change of note was the Latvian decision to convert all existing public schools to Latvian-only, beginning in September 2023.
[30] While policies have previously been in place to encourage the use of Latvian over Russian in education settings, these rules were inconsistently enforced and schools were not monitored.
