Civilization

# Andean

The Andean highlands and littorals sustained complex polities with distinctive infrastructural, ritual, and economic systems forming a durable civilizational complex.

## The framework read

The author's reading of this civilization.

- Geographic core: Andean highlands with vertical archipelagos linking ecological tiers; coastal nodes.

- Cultural-linguistic cohesion: shared ritual infrastructures and state cults; Quechua/Aymara spheres in later periods.

- Political-economy: labor taxation (mit’a-like systems), road networks, and storage regimes.

- Continuity: recognizable civilizational patterns across Chavín, Moche, Wari, Tiwanaku, and Inca.

### Why it works — and how it breaks

- Success vector: S (vertical archipelago coordination, road networks, storage regimes) + G (organized defense, labor mobilization via mit'a).

- Failure modes: S fragmentation (succession disputes, regional competition) + B disease catastrophe at contact (Columbian Exchange) → rapid collapse; internal breakdown in some cases (Wari, Tiwanaku).
