What if some Roman EMperor (your choice who), or even Caesar or Antony decided to conquer the entirety of the old Alexandrine empire (Alexander the Great's Empire that was divided)? What would that mean for Rome, firstly; and how would it be accomplished?
Does anyone know why such an attempt was never made/failed?
PS: My knowledge on Roman history is dodgy at best. I know the five good emperors, and the Julio-CLaudian emperors, Caesar, Antony and Cleopatra, further than that, zip.
Any comments welcome.
