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.
Ethnic demography of Kazakhstan
Kazakhstan's dominant ethnic group, the Kazakhs, traces its origin to the 15th century, when a number of Turkic and some Mongol tribes united to establish the Kazakh Khanate. With a cohesive culture and a national identity, they constituted absolute majority on the land until Russian colonization.
Russian advancement into the territory of Kazakhstan began in the late 18th century, when the Kazakhs nominally accepted Russian rule in exchange for protection against repeated attacks by the western Mongolian Kalmyks. In the 1890s, Russian peasants began to settle the fertile lands of northern Kazakhstan, causing many Kazakhs to move eastwards into Chinese territory in search of new grazing grounds.
