It can hardly be doubted that in very ancient times the whole Slavic race spoke only one language. This seems however very early to have been broken up into several dialects; and such indeed must have been the natural result of the wide extension of the people. Eginhard, the secretary and historian of Charlemagne, (ob. 839.) calls the Slavic nations, whom his hero subjugated, Veletabae, Sorabae, Obotrites, and Bohemians; and mentions expressly that they did not all speak the same, but a very similar language.
