Darius the Great
Key Takeaways
- Darius I brought the Achaemenid Persian Empire to its greatest size.

If Cyrus the Great founded the Persian Empire, Darius the Great made it work. Under his rule the Achaemenid Empire reached its greatest size and became one of the best-organized states the ancient world had ever seen.
The great organizer
Darius divided his vast realm into provinces called satrapies, each governed by an appointed official and watched by royal inspectors. He standardized coinage, built the Royal Road for messengers, and raised the magnificent ceremonial capital of Persepolis. His empire stretched from the Indus Valley to the edge of Europe.
Persia and Greece
Darius also launched the first Persian invasion of Greece — and met a famous check at the Battle of Marathon in 490 BC, where the Athenians turned back his army. He died planning revenge, leaving the war to his son Xerxes I. A century later the empire he had built so carefully would fall to Alexander the Great, but in the age of Achaemenid Persia Darius stood as its supreme administrator.
Expanded the Persian Empire from the Indus to the Balkans, organized it into satrapies with roads, coinage and a postal system, and launched the first Persian invasion of Greece, checked at Marathon.
