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.
Eastern Orthodox Slavs
Orthodox Slavic nations today include the Belarusians, Bulgarians, Macedonians, Montenegrins, Russians, Serbs and Ukrainians. They inhabit a contiguous area in Eastern Europe stretching from the northeast in the Baltic Sea to the Carpathian and Balkan Mountains in the southeast and southwest; from the north in the Russian Federation to the southwest in Macedonia near the Greek border. There are also major Orthodox Slavic population hubs and communities in North Asia (predominantly Siberia), the Americas (predominantly North America), and significant diaspora groups throughout the rest of the world.
