Eastern Orthodox Christianity, first introduced by missionaries from the Byzantine empire, is practiced by the majority of Slavs. Present-day Slavic people are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubs, Poles, Slovaks, and Sorbs) and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes). Slavs are the largest ethno-linguistic group in Europe. Today, there is a large Slavic diaspora throughout the Americas, particularly in the United States, Canada, and Brazil as a result of immigration. From the early 6th century they spread to inhabit most of Central, Eastern and Southeastern Europe. They are native to Eurasia, stretching from Central, Southeastern and Eastern Europe, all the way north and eastwards to Northeast Europe, Northern Asia ( Siberia and the Russian Far East), and Central Asia (especially Kazakhstan and Turkmenistan), as well as historically in Western Europe (particularly in Eastern Germany) and Western Asia (including Anatolia). Slavs are an ethno-linguistic group of people who speak the various Slavic languages of the larger Balto-Slavic linguistic group of the Indo-European languages. 31 million Poles are migrants to other nations)
