In Part 1 you looked at how the Aztec and Inca organised political power and used warfare. This micro finishes the section: how their economies and societies worked, what they believed, and what they created culturally.
Two case studies: The syllabus requires these last three bullets to be taught through a case study of two indigenous societies — here, the Aztec (Mexica) Empire (c1345–1521) and the Inca Empire (Tawantinsuyu) (c1400–1533).
The big idea: Neither empire used money. Instead, both economies ran on tribute and organised labour. How each empire collected tribute reveals how centralised and controlling it really was.
The Aztec tribute system
The Aztec Empire was really a network of conquered city-states (altepetl) that kept their own local rulers but had to pay tribute to the Triple Alliance (Tenochtitlan, Texcoco, Tlacopan). Tribute was recorded in pictographic codices such as the Codex Mendoza, which lists exactly what each province owed.
- Tribute in goods — maize, cotton cloth, cacao beans, feathers, gold dust, jade and even live animals, delivered on a fixed schedule (often every 80 days)
- Tribute in labour — the coatequitl, a labour draft used to build causeways, temples and canals in Tenochtitlan
- Landholding — most land was held communally by the calpulli (a clan-based neighbourhood unit), not owned individually; nobles held separate estates worked by commoners
- Long-distance traders (pochteca) — a specialist merchant class who carried luxury goods across and beyond the empire, and also acted as spies and diplomats
- Marketplaces (tianguis) — huge markets such as Tlatelolco, where goods were exchanged by barter, sometimes using cacao beans or cloth as a rough currency
The Inca mit'a system
The Inca ran a much more centrally planned economy. There was no marketplace trade at all in most of the empire — the state itself redistributed almost everything.
- Mit'a — a rotational labour tax: every household owed a set number of days of labour per year to the state instead of goods, working on roads, terraces, temples or in the army
- Ayllu — the basic Inca social and landholding unit, an extended kin-group that farmed land collectively and redistributed the harvest among its members
- Three-way land division — land was split for the community, for the state, and for the state religion, with the ayllu farming all three parts
- Qollqa (storehouses) — vast networks of state storehouses along the road system held surplus food and goods, used to feed workers, armies and disaster relief
- Quipu — knotted cords used by trained officials (quipucamayocs) to record tribute owed, labour performed and census data — a record-keeping system rather than writing
Compare, don't just describe: In a Paper 3 essay on 'economic and social structures', make sure you compare: Aztec tribute flowed upward from conquered provinces to the capital, while Inca mit'a was labour-based and the state redistributed goods back down to communities. Same problem (no money), two different solutions.

Both empires were polytheistic, and in both, religion and political power were tightly bound together — rulers claimed descent from, or a special relationship with, the gods.
Aztec religion
- Worshipped hundreds of gods; the most important were Huitzilopochtli (sun and war god, patron of Tenochtitlan) and Tlaloc (rain god)
- Believed the sun needed human blood to keep moving across the sky, so warfare partly existed to capture prisoners for ritual sacrifice
- The Emperor (Huey Tlatoani) was seen as a semi-divine intermediary between the people and the gods
- Priests held huge social status, ran schools (calmecac) for nobles, and kept the ritual calendar
Inca religion
- Also polytheistic, but state religion was built around Inti, the sun god, and Viracocha, the creator god
- The Sapa Inca (emperor) was believed to be a direct descendant of the sun — this justified his absolute authority
- Practised ancestor worship: dead rulers were mummified and kept as if still alive, still 'owning' their estates
- Believed in Pachamama (earth mother) and a close relationship between humans and nature, especially the mountains (apu)
Religion legitimised power: In both empires, religion was not separate from politics — it justified the ruler's right to demand tribute and labour. If the Sapa Inca is the sun's descendant, or the Huey Tlatoani speaks for the gods, disobeying the ruler becomes disobeying the gods.
- Relationship between man and nature — Aztec cosmology saw the world as fragile and cyclical (the sun could die without sacrifice); Inca cosmology saw mountains, rivers and the earth itself as living, sacred beings
- Religious buildings as political statements — the Aztec Templo Mayor in Tenochtitlan and the Inca temple of Coricancha (Cusco) were both the literal and symbolic centres of empire
- Ritual and calendar — both cultures used complex calendars (Aztec: 260-day ritual calendar + 365-day solar calendar; Inca: solar calendar tied to agriculture) to time festivals and sacrifices
Worked micro-example: Question type you might see: 'Compare and contrast the relationship between religion and political power in two indigenous societies of the Americas.'
Method
1
Shared idea
State the shared idea: rulers use religion to legitimise rule.
2
Aztec example
Give ONE precise Aztec example: Huey Tlatoani as intermediary + sacrifice justifying warfare.
3
Inca example
Give ONE precise Inca example: Sapa Inca as son of the sun + ancestor worship.
4
Compare
End with a comparative sentence on the difference: sacrifice-centred vs descent-centred legitimacy.
Shared idea → Aztec example → Inca example → the difference

The final bullet asks about culture: written and unwritten language, and contributions to science and the arts. This is where the two empires differ most sharply.
| Feature | Aztec | Inca |
|---|---|---|
| Writing | Pictographic/logographic codices (bark paper) recording history, tribute and religion | No true writing; used quipu (knotted cords) for numerical records only |
| Number system | Base-20 (vigesimal) counting system | Decimal system encoded in quipu knots |
| Astronomy/science | Highly accurate 365-day solar calendar + 260-day ritual calendar (the Calendar Stone) | Precise agricultural/solar calendar; sophisticated terrace farming and irrigation engineering |
| Engineering | Chinampas (raised farming islands) on Lake Texcoco; causeways into Tenochtitlan | Road network (over 30,000 km) with rope suspension bridges; terracing on steep mountainsides |
| Arts | Featherwork, goldwork, poetry (in Nahuatl), monumental stone sculpture | Fine textiles (considered a prestige good), goldwork, monumental stonework (Machu Picchu, Sacsayhuamán) |
- Nahuatl — the Aztec language, still spoken by over a million people in Mexico today; used for poetry and oral history alongside the codices
- Quechua — the Inca language, spread across the empire as an administrative language, still spoken by millions in the Andes
- Chinampas — Aztec floating gardens that made farming possible around Tenochtitlan's lake, showing engineering adapted to environment
- Terracing — Inca stepped fields cut into mountainsides, showing engineering adapted to a completely different environment (steep Andes, not a lake)
- Monumental architecture — Templo Mayor (Aztec) and Sacsayhuamán/Machu Picchu (Inca) both used architecture to project state power, not just religion
Same problem, different answer: Notice the pattern across this whole section: both empires solved the same problems (recording information, farming difficult land, moving goods, justifying rule) but the local environment and local traditions shaped different solutions. That comparative reasoning is exactly what Paper 3 rewards.
Don't overreach the syllabus: Only named individuals and events in the guide are examinable. For this section, you do NOT need names of specific Aztec or Inca artists or scientists — focus on the systems (tribute, mit'a, quipu, codices, calendars) named in the bullets, not extra facts from outside reading.
