Henri Gregoire has tried to identify this Chrovatos with Kuvrat, the ruler of the Protobulgarians who rebelled against the Avars, recorded by other sources in the first third of the seventh century. As a matter of fact, now it is certain that Kuvrat lived in the North-Pontic steppes, not in Pannonia. He was the father of Asparuch, the ruler of the Protobulgarian group that immigrated to Moesia. Chrovatos was an invented eponym hero, like other such mythical ancestors of the European peoples.
It was a frequent custom With the Hunnic hordes to take their names from some noted leader, and it is therefore exceedingly probable that on their great outbreak the followers of Kubrat should have called themselves Kubrati, that is, Croats.I have argued in a previous paper of this series that the Croats or Khrobati of Croatia were so called from a leader named Kubrat or Khrubat. I would add here an addition to what I have there said, viz., that the native name of the Croats, given variously as Hr-wati, Horwati, cannot surely be a derivative of Khrebet, a mountain chain, as often urged, but is clearly the same as the well known man's name Horvath, familiar to the readers of Hungarian history and no doubt the equivalent of the Khrubat or Kubrat of the Byzantine writers, which name is given by them not only to the stem father of the Bulgarian kings, but to one of the five brothers Who led the Croat migration
