When we think in ancient history all up the islamic conquests, we usually take Iran, independent of it's ruling dynasty, be the Sassanids, the Parthians or the Achaemids as the main power in the middle east, and some times as the main power in the known world (behind china ofc), and while iran remained a regional power in the mdidle east, it failed to become a large continent covering empire, like the Russians, the ottomans, or even the Mughals and the Timurids. Why such a thing happened?
Edit: I classified the Ottomans as continent covering empire since it held over most of north africa
Edit2: This is way after the end of the Achaemid empire and the Sassanid empire, I'm talking about after the end of the abbasid rule forward
