Cyrus the Great

The Persian Empire is one of the most mysterious major civilizations in the ancient world.

Persia became an empire under the Achaemenid king, Cyrus the Great, who created a policy of religious and cultural tolerance that became the hallmark of Persian rule.

The empire that Cyrus left behind expanded to India and Greece under the reign of Darius I, who built the capital of Persepolis.

Among the engineering feats of the Persian Empire were an innovative system of water management accomplished with simple tools; a cross-continent paved roadway stretching 1500 miles that made travel safe and communication possible; a canal linking the Nile to the Red Sea, a forerunner of the modern Suez Canal; and the creation of one of the Seven Wonders of the World
