I'm curious as to why these three tribes, all Arab, and at roughly the same time, were all similarly Christian, were never able to unite either as one force.
It seems to me that it was likely down to Roman and Persian interference on the part of the Lakhmids and Ghassanids, but the Tanukhids less so.
Could the Tanukhids have been able to play a role in creating a Christian Arab confederacy stretching across northern Arabia? If so, where would it be centered? Around Al-Hira - threatening the Persians, near the border with the Romans? Or would it be nomadic until such time at it could claim a city ruled historically by the Ghassanids or Lakhmids? (Say somewhere in the Hedjaz, or the Persian Gulf)
Is there anyone on the forums with a solid grasp on the Arab clients at this time?
