 The name "Carantania" itself begins to appear in historical sources soon after 660.The first clear indication of a specific ethnic identity and political organisation may be recognised in the geographical term "Carantanum" which Paul the Deacon used in reference to the year 664, and in connection to which he also mentioned a specific Slavic people ("gens Sclavorum") living there.When about 740 Prince Boruth asked the Bavarian duke Odilo for help against the pressing danger posed by Avar tribes from the east, Carantania lost its independence.
