Post-Classical Worlds
Religions, trade networks, and empires after antiquity—how ideas and power traveled across continents.
500 CE → 1200 CE
In one minute..
The mental model for this era
is where the world connects. After the classical empires fragment, new political orders emerge alongside powerful universal religions. Trade routes, pilgrimages, and conquest link distant societies, spreading ideas, technologies, and institutions across Afro-Eurasia.
Why this era matters
- Major world religions—Islam, Christianity, Buddhism, Confucian revival—shape law, identity, and daily life.
- Long-distance trade networks knit together regions that had never been directly connected before.
- States learn to rule without Rome-style bureaucracy, relying on religion, tribute, and elite cooperation.
What to watch for
- How religion legitimizes rulers and constrains power
- How trade routes (Silk Roads, Indian Ocean) move more than goods
- How cities act as nodes—ports, pilgrimage centers, capitals
- What happens when empires rule diversity rather than uniformity
