The world that Alexander the Great built and his generals maintained for the first time saw the creation of a Greek political sphere from Macedon to the Indus, largely upending the rule of the Achaemenid monarchs prior. Surprisingly, the system he and his successors developed would last for centuries politically, and for centuries after, even as the last states that derived themselves from the legacy of Alexander were conquered, the cultural legacy would last another few centuries, and still has great influence even today. The challenge here is to dismantle or render politically impotent the world and order that Alexander and his successors have created as soon as possible, and to erase the cultural traces of Hellenization as well(this was done with the Sassanids in Mesopotamia and Iran-proper, as part of the Eranshahr resurgence) earlier. What would be needed to accomplish this result? The POD is after the Battle of the Persian Gates, meaning the Achaemenids have been militarily defeated, but a loose alliance of chiefs and satraps proclaiming nominal fealty to a "Great King" remain. What would be needed? Earlier and deadlier Diadochi wars? Alexander dying earlier? A resurgent dynasty in Persis, perhaps the Frataraka? Or replacing the Arsacids with another, more hostile nomadic polity? What would be the effects?
