THE RECORD
What changed
During the thirteenth and twelfth centuries BCE, palace systems across the eastern Mediterranean were destroyed or reduced and exchange networks weakened. Iron use expanded gradually over subsequent centuries.
EVIDENCE
What remains
Destruction layers, interrupted texts, settlement change and shifts in metal assemblages reveal both rupture and continuity by region.
WHY IT MATTERS
Why it matters
Complex interdependence can be both strength and vulnerability. Iron was not an instantly superior replacement for bronze; it spread through new resource networks and skills.
OPEN QUESTION
Where interpretation begins
No single invasion explains the change. Drought, earthquakes, conflict, migration and systems failure carried different weight by region, and even ‘collapse’ can oversimplify.
