Part 7/14:
Economic Decline
Economic explanations focus on the weakening of the empire's financial and agricultural systems:
- Soil exhaustion from over-farming 
- Decline in urban populations and arable land 
- Increasing wealth disparity and declining civic engagement 
- Reliance on slave labor, which decreased over time 
- Inflation and currency debasement during later periods 
These issues drained resources and dissuaded effective military and political response to external threats.
