causal hypothesis · HYP-MULTICAUSAL-STAGGERED-CASCADE
Regionally staggered multi-causal cascade
Different regions entered crisis through different combinations of structural fragility, food stress, elite conflict, warfare, mobility, and network disruption, with failures in one area amplifying vulnerabilities elsewhere.

Research assessment
statement
Different regions entered crisis through different combinations of structural fragility, food stress, elite conflict, warfare, mobility, and network disruption, with failures in one area amplifying vulnerabilities elsewhere.mechanisms
- regional drought reduces harvests
- food and tribute demands strain dependent states
- political fragmentation disperses military capacity
- mobile warfare and raiding exploit weakened nodes
- maritime insecurity and political failure disrupt trade
- shortages and insecurity stimulate further migration and reorganization
important caveat
The whole chain is not equally demonstrated in every region. The strongest linked case in this release is Hatti-Ugarit; the Aegean requires a different balance of factors.Research description
