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. > > The first Persian Empire under Cyrus the Great soon became the world’s first superpower. It united under one government three important sites of early human civilization in the ancient world: Mesopotamia, Egypt’s Nile Valley and India’s Indus Valley. > > Darius the Great, the fourth king of the Achaemenid Empire, ruled over the Persian Empire when it was at its largest, stretching from The Caucasus and West Asia to what was then Macedonia (today’s Balkans), the Black Sea, Central Asia and even into Africa including parts of Libya and Egypt. He unified the empire through introducing standard currency and weights and measures; making Aramaic the official language and building roads.
