The framework read

The author's reading of this civilization.

  • Geographic core: highland–lowland nodes from Oaxaca and the Valley of Mexico to Maya regions.
  • Cultural-linguistic cohesion: writing/calendrical systems and shared ritual-architectural repertoires across polities.
  • Political-economy: tribute, market exchange, and ritual centers linking urban and rural zones.
  • Continuity: civilizational frames persist across Olmec, Maya, Teotihuacan, Toltec, and Mexica phases.

Why it works — and how it breaks

  • Success vector: S (ritual-infrastructure coordination, calendrical systems enabling agricultural planning) + G (organized defense, tribute extraction).
  • Failure modes: S fragmentation (city-state competition, elite conflict) + B disease catastrophe at contact (Columbian Exchange) → rapid collapse; internal breakdown in some cases (Teotihuacan).
