Civilization

# Mesoamerican

Mesoamerica developed enduring urban, calendrical, and ritual-institutional complexes across multiple polities with recognizable civilizational continuities.

## 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).
