The Eastern Mediterranean after Alexander
Between Alexander's death and the Arab conquests: the Successor kingdoms and the smaller monarchies that grew in their gaps, a Jewish state that made itself and was unmade, and the Arab powers that held the desert between Rome and Iran. Seven of the ten end against Rome, which is most of what the region has to say.
The line below is a time axis. Position on it is date, so concurrency is visible: concurrent polities sit side by side rather than in sequence.
14 sourced edges run between this region and another, to Roman Empire, Achaemenid Empire, Seleucid Empire, Sasanian Empire, Byzantine Empire, Rashidun Caliphate and Macedonian Empire. Those are not drawn on this line — a thread that crossed regions would assert a sequence nobody cited — but they are on each polity’s own page.
