Slavs
Slavs are an Indo-European ethno-linguistic group who speak the various Slavic languages of the larger Balto-Slavic linguistic group. They are native to Eurasia, stretching from Central, Eastern, and Southeastern Europe all the way north and eastwards to Northeast Europe, Northern Asia (Siberia), the Caucasus, and Central Asia (especially Kazakhstan and Turkmenistan) as well as historically in Western Europe (particularly in East Germany) and Western Asia (including Anatolia). From the early 6th century they spread to inhabit the majority of Central, Eastern and Southeastern Europe. Today, there is a large Slavic diaspora throughout North America, particularly in the United States and Canada as a result of immigration.
Russians in Kazakhstan
Although Nazarbayev is widely credited with peaceful preservation of the delicate inter-ethnic balance in Kazakhstan, hundreds of thousands of Russians left Kazakhstan in the 1990s due the perceived lack of economic opportunities. A number of factors contributed to this situation. Following independence from the Soviet Union, the Kazakh government adopted a policy of developing the state language that sought to affirm the ethnically Kazakh nature of the country and promote Kazakh language and culture. One aspect of this policy was the government's decision to define Kazakhstan as the national state of the ethnically Kazakh people in the country's first constitution in 1993 and again in its second constitution in 1995.
