Early Prague Chronicles

One of the earliest Czech historians was Cosmas of Prague, who wrote his chronicles early in the twelfth century. There are yet earlier German chronicles which make mention of the Bohemians, but the city of Prague didn't yet exist in the days in which they were written. Those German chronicles suggest that the Bohemians who came into their land some time in the sixth century were at one time tributary to the Avari, an Asiatic tribe which had taken possession of the greater part of present-day Hungary, and were rather a nuisance to Western Europe.

It will be remembered that Charlemagne had forceful argument with these Avari; it had something to do with that worthy's trip to visit the Empress of the East; there was a squabble about fares, river dues and such matters. However, this is vieux jeu, and has nothing to do with Prague. The Avari were devoted to the time-honoured practice of robbing and ravishing their neighbours, among them the Bohemians. These latter seem to have borrowed one Samo the Frank, a strong man, from one of the northern Slavonic tribes, and as he proved a success, invited him to be King over them.

Samo accepted the invitation, and is said to have founded the first great Slavonic State with Bohemia as nucleus and a strong castle at Vyšehrad. The neighbouring Franks became uneasy at Samo's increasing importance, and under Dagobert, their King, invaded Bohemia, to be badly beaten at Wogastisburg, which, according to Count Lützow, was near the present town of Cheb. Samo extended his territory after this victory, and appears to have lived till about the middle of the seventh century.

There ensues a complete lapse in the chronicling of the history of Bohemia until Cosmas took up the tale.
