After the fall of the Roman empire, it was the nucleus of the kingdom of Carentania, which was founded by Samo, a Frankish adventurer, but soon fell to pieces after his death.
As to their present name, signifying in its present Russian spelling "self-eaters," many ingenious theories have been advanced, but that proposed by Schrenk, who derived the name "Samo-yedes" from "Syroyadtsy," or "raw-eaters," leaves much to be desired.
About 590 the district was settled by the Slovenes, or Corutanes, a Slavonic people, who formed part of the kingdom of Samo, and were afterwards included in the extensive kingdom of the Avars.
Here in the first half of the 7th century Samo repulsed the invading hordes of the Avars, which threatened the independence of the newlysettled Slavonic inhabitants; here also Wratislas II.
The first of their rulers mentioned in history is Samo, who is stated to have defeated the Avars, a Turanian tribe which had for a time obtained the overlordship over Bohemia.
Samo also defeated the Franks in a great battle that took place at Wogatisburg (630), probably near the site of the present town of Eger.
After the death of Samo the history of Bohemia again becomes absolutely obscure for about 130 years.
