Ethiopian / Axumite
TibetanDetails
- Basins concentrate populations and administrative capacity through predictable surplus (e.g., Nile, Yellow, Indus).
- Littorals create maritime hubs that transmit technologies, beliefs, and institutions across regions (e.g., Mediterranean, Indian Ocean).
- Corridors enable mobility, pastoral polities, and cultural transmission that periodically transform agrarian cores (e.g., Eurasian steppe).
