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.
Kazakhs
The Kazakhs are descendants of the Turkic and medieval Mongol tribes – Argyns, Dughlats, Naimans, Jalairs, Keraits, Khazars, Qarluqs; and of the Kipchaks and Cumans, and other tribes such as the Huns and Nogais, and ancient Iranian nomads like the Sarmatians, Saka and Scythians who populated the territory between Siberia and the Black Sea before the 5th and 13th centuries AD.
