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 Autonomous Socialist Soviet Republic
The Kazak ASSR that succeeded the recently expanded Kirghiz ASSR included all of the territory making up the present-day Republic of Kazakhstan plus parts of Uzbekistan (the Karakalpak Autonomous Oblast), Turkmenistan (the north shore of Kara-Bogaz-Gol) and Russia (parts of what would become Orenburg Oblast). These territories were transferred from the Kazak ASSR over the following decade.
