ABSTRACT
The Alexandrian campaign probably changed the world more than any other single event in ancient history. Admittedly, Alexander did not have time to expand westwards from the empire he built out of the conquered Persian Empire and the half of the Greek-speaking world that was under his rule. Indeed, the Empire only outlived its creator by a few years. Nevertheless, in the hands of energetic generals from Alexander's army the territory he conquered became a number of substantial territorial states, hereditary monarchies, with government, finance and the military set up according to what were then modern, rational fourth-century BC principles.
