The former Soviet Union was a country largely comprised of numerous ethnic minorities, with over 100 different ethnic groups. It included republics such as Ukraine, Georgia, and the Baltic states, each with its own distinct national identity and culture. This diversity contributed to various political and social tensions, ultimately leading to the dissolution of the Soviet Union in 1991.
15 republics declared independence and Soviet Union no longer existed.
Ethnic favoritism is when the members of one particular ethnic group are favored over the members of other ethnic groups in how government or other large organizations treat them. One historical example of ethnic favoritism is the treatment of ethnic Russians in the former Soviet Union. Ethnic Russians were able to settle in regions where a majority of the population were not Russian, yet the Russian language was the primary language. In the Soviet army, Ethnic Russians, Ukrainians, and members of other western ethnic groups were the majority in the technical and front-line tasks, while the Asian ethnic groups were relegated to support and construction functions. Another example is the treatment of whites and blacks in Apartheid South Africa, where the whites had more government services, better housing, better education, etc., than the blacks.
The Soviet union fail
The soviet Union set off an atomic bomb.
Ethnic tension in the Soviet Union and Yugoslavia escalated due to a combination of historical grievances, nationalist sentiments, and the suppression of ethnic identities by centralized authorities. In both cases, diverse ethnic groups were forced to coexist within artificial national boundaries, leading to competition for political power and economic resources. The weakening of central control—especially during periods of reform—allowed suppressed nationalist movements to resurface, resulting in violent conflicts and the eventual disintegration of both states. These tensions were exacerbated by propaganda and political manipulation, fueling divisions among ethnic groups.

Germany wouldn't listen to the Soviet Union
This question is too broad, the Soviet Union spanned for almost 70 years. I will be happy to answer a more specific question.
The majority are Latvian followed by large Russian community. There are also other former Soviet union country ethnic groups - Belorussian, Ukrainian, Polish. Some people have been living in Latvia's territory for a much longer time, such as Livonians (the first people known historically to live in the Latvia's territory), Romanies, Jews.
