For many centuries the Slavic tribes used the same common language. Starting with the migration into Eastern Europe some dialectical differences began to develop among the various tribes. Generally, linguists divide the Slavs into three main groups - Western Slavs, Southern or Yugoslavs, and Eastern Slavs. The Western Slavs embrace modern nations of Czechs, Slovaks, Lusitian Serbs and Poles. Southern Slavs include Serbs, Croats, Slovenians, Macedonians and Bulgarians. The Eastern Slavs are subdivided into three separate branches: Russians (or Muscovites), White (or Bielo-Russians) and Rusyns (or Ukrainian).
