Section 1
Persia Governs a Vast Empire
Key Idea
The Persian Empire grew into the largest the world had yet seen. To manage this vast territory, King Darius I divided it into provinces called satrapies. A governor, known as a satrap, ruled each province, collected taxes, and enforced the king’s laws.
To unite the empire, the Persians built a system of roads. The famous Royal Road allowed messengers and a professional army to travel quickly across great distances. This organization helped Persian kings maintain control over their diverse lands before their conflict with the Greeks.
