The Persian Empire is the name given to a series of dynasties centered in modern-day Iran that spanned several centuries—from the sixth century B.C. to the twentieth century A.D. The first Persian Empire, founded by Cyrus the Great around 550 B.C., became one of the largest empires in history, stretching from Europe’s Balkan Peninsula in the West to India’s Indus Valley in the East. This Iron Age dynasty, sometimes called the Achaemenid Empire, was a global hub of culture, religion, science, art and technology for more than 200 years before it fell to the invading armies of Alexander the Great.
CYRUS THE GREAT
The Persian Empire started as a collection of semi-nomadic tribes who raised sheep, goats and cattle on the Iranian plateau.
Cyrus the Great—the leader of one such tribe—began to defeat nearby kingdoms, including Media, Lydia and Babylon, joining them under one rule. He founded the first Persian Empire, also known as the Achaemenid Empire in 550 B.C.
The first Persian Empire under Cyrus the Great soon became the world’s first superpower.
