Recently I was thinking about how the Middle East ended up in it's current state. The current borders can be traced back to WWI when the allied powers divided up the Ottoman Empire among themselves after the war.
If we go way back in time to when the Roman Empire was around, the eastern empire never really fell. The Middle east was part of the Byzantine Empire, and when that empire shrunk it was because of the rise of a strong Islamic empire. That faded over time, but then the Turks took over. So all the way up to WWI there is never really a time where there hasn't been an empire in control of the middle east. After WWI and the Ottoman Empire was dissolved was the first time.
The western part of the Roman Empire obviously fell, though, and left a power vacuum in Western Europe. After a ton of fighting we ended up with the nation-states of today. It seems to me that the situation in the middle east after WWI to the present is similar to the fall of Rome in the west. The difference is that in the middle eastern case western powers defined the borders at the beginning of the process (and continually interfered to protect their interests).
Is anything to this connection I have made, or is it too vague of a connection to be very interesting?
If you are saying that the Arab Middle East, from Palestine to Iraq, and from Syria to what is today Jordan, was never a centre of power since the fall of the Abbasids to the Buyids, you would be correct.
Egypt, under the Mamlukes would continue to be a strong "Sultanate" (run by various Mamluke families), until it was conquered by the Ottomans in 1517-18. Since that date, the Arab Middle East was not the centre of any Empire or Kingdom until independence, in the 1940s and 50s.
As to if you can draw a parallel from the Western Roman Empire disintegrating into France (Kingdom of Franks), England (Anglo-Saxon kingdoms), Spain (the Suebi and Visigoth Kingdoms) and Italy (divided between Ostrogoths, Lombards and Byzantines), to the Middle East in modern times, I don't think you can, and I would not recommend making that parallel connection.
I still find your question to be very vague and hard to understand, so if you can ask a more definitive question, and can give you a more definitive response.
