A visual atlas of pre-industrial history
How Everything
Evolved
Our World in Data made the modern world legible. This project attempts the same thing for everything that came before it.

History is a sequence of domestications.
Humans domesticated fire, landscapes, water, plants, animals, metal, labor, information, belief, violence—and one another. Each system expanded what societies could coordinate. Each also created new dependencies and new ways to fail.
This is not a neutral encyclopedia. It is a source-traceable argument told through maps, timelines, models, and comparisons. Where the evidence is fragmentary, the uncertainty belongs in the explanation.
The atlas
History as systems
you can see.
Pages are published as their evidence and visuals become strong enough. Draft pages contain live, auditable work; research pages show the committed sequence.
500 BCE–476 CE
Rome
How an Italian coalition became a continental state—and why the Roman state survived its western court.
7000–2900 BCE
Uruk and the first states
Water, grain, writing, and organized labor made people and landscapes newly legible—without making control complete.
4000 BCE–1550 CE
The cradles of civilization
Cities, states, monuments, notation, coordination, and collapse followed different clocks and pathways.
3300–1050 BCE
The Bronze Age world system
Distant materials and selective institutions made societies powerful, connected, and vulnerable without producing one synchronized collapse.
2000–400 BCE
The Iron Age transformation
Iron became transformative when fuel, furnaces, skills, exchange, and institutions made production repeatable—not when someone first found the metal.
550 BCE–651 CE
Persia and territorial empire
Roads, provinces, obligations, coalition armies, and reusable institutions made imperial scale outlast one dynasty.
475 BCE–220 CE
Qin and Han China
Competition built mobilizing systems; standards and a maintained logistics ecology made distance governable.
2600 BCE–550 CE
India from cities to empires
Shared measures, monsoon ecologies, cities, empires, religions, and trade coordinated South Asia on overlapping geographies.
3500 BCE–1500 CE
The Steppe
Pastoral mobility preceded cavalry, then repeatedly changed agrarian states, trade, warfare, languages, and populations.
30–800 CE
Christianity
Letters, cities, bishops, ritual, and charity made institutions that outlasted western empire.
632–1258 CE
The Caliphates
Conquest joined old imperial worlds; administration, Arabic, law, trade, and scholarship made the connection last.
800–338 BCE
Greek City-States
Small political territories made citizenship intensely local while leagues and empires repeatedly tested the limits of the polis.
323–30 BCE
Hellenistic Kingdoms
Alexander’s successors built royal systems from mixed armies, capitals, settlements, money, and durable local institutions.
200 BCE–1500 CE
Silk Roads
Changing chains of oasis economies, merchants, states, religious institutions, and sea lanes connected Eurasia.
500–1500 CE
Medieval Europe
Layered power coexisted with expanding manuscripts, towns, church institutions, markets, and territorial states.
300–1500 CE
African States and Trade
River valleys, highlands, cattle landscapes, ports, mines, and corridors produced many routes to political scale.
500 BCE–1500 CE
Southeast Asian Mandalas
Workshop ports, river systems, temples, and overlapping centers made authority mobile across a maritime region.
1000 BCE–1500 CE
Mesoamerican Cities and States
Dense cities and countryside depended on engineered landscapes, writing, markets, and political systems that repeatedly reorganized.
1000 BCE–1533 CE
Andean Worlds and the Inka
Communities linked unlike ecological floors through settlements, caravans, colonies, and state labor.
1206–1500 CE
Mongol Eurasia
Conquest joined armies, relays, merchants, disease ecologies, and successor states across a continental space.
1450–1800 CE
Gunpowder Empires
Cannon changed walls, muskets changed infantry, and paying for both changed states.
1400–1815 CE
Oceanic Navigation
Open-ocean routes joined continents through seasonal knowledge, skilled labor, monopolies, exchange, and coercion.
1500–1800 CE
The Great Divergence
Wages, energy, ecology, states, and empire created unequal incentives before factories transformed output.
