Who were the avars?

Dec 2012
There used to be a theory similar to the Huns/Xiongnu link theory that linked the Avars with the Juan-Juan/Ruan-Ruan tribe of the Mongolian steppes. No idea if it's still credible today or not, but it certainly was considered as recently as the 80s/90s.

wow the great tigerstar himself! love your youtube vids! So then were the Avars more likely in your opinion to be of Turkic/Mongol or Tungastic origins?
