A static map of the Bronze Age lies by omission. It freezes one instant of something that was, in truth, constant churn — warriors moving, refugees dispersing, pottery and script and metallurgy leaking across the Mediterranean faster than any single polity could control.
Rendered as a field you can scrub through time, around 1300 BC you watch combatant volumes rise, settlers and refugees disperse in their thousands, and three attribute streams — technology, culture, language — transfer along the trade routes like current along a wire.
Told this way, history stops being a list of dates and becomes what it was: a dynamical system. The sovereign-order question — how negotiated arrangements survive shock — is not abstract here. It is the literal content of the collapse.
