Research assessment
proposed mechanism
Cheaper or more available iron altered warfare, undermined bronze-dependent elites, and enabled new groups.tests
- anomalies
- Technological timing is the central falsifying issue.
- geography
- Weak as a universal explanation.
- chronology
- Weak. Major adoption does not securely precede the first collapses.
- physical or social mechanism
- Possible as a long-term transformation, not an initiating shock.
- survivors and counterexamples
- Does not explain why some bronze-dependent systems survived or why failures were staggered.
Research description
