World History · Era— 500 BCE — 500 CE —

Empires & ideas that outlasted them.

Persia, Greece, Rome, Han China, Maurya, Gupta. The era that gave us most of the philosophy, religion, and political theory the modern world still argues about.

What you need to know

The thousand years from roughly 500 BCE to 500 CE were the great age of empire and idea. The Persian Empire under Cyrus and Darius established the template for multi-ethnic rule. Greek city-states pushed back, then Alexander conquered everything from Egypt to India. Rome consumed the Mediterranean. In China, the Qin unified the warring states and the Han built four centuries of imperial culture. India saw the Maurya and Gupta. And in this same era — almost simultaneously — Confucianism, Buddhism, Christianity, Hinduism, and Greek philosophy emerged. The empires fell. Their ideas didn’t.
