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.
Kazakh language
The Kazakh language has its speakers (mainly Kazakhs) spread over a vast territory from the Tian Shan to the western shore of the Caspian Sea. Kazakh is the official state language of Kazakhstan, with nearly 10 million speakers (based on information from the CIA World Factbook on population and the proportion of Kazakh speakers). In China, more than one million ethnic Kazakhs and Kazakh speakers reside in the Ili Kazakh Autonomous Prefecture of Xinjiang.
