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. It united under one government three important sites of early human civilization: Mesopotamia, Egypt’s Nile Valley and India’s Indus Valley.
Where Is Persia?
At its height, the Persian Empire stretched from Europe’s Balkan Peninsula—in parts of what is present day Bulgaria, Romania, and Ukraine—to the Indus River Valley in northwest India and south to Egypt.
The Persians were the first people to establish regular routes of communication between three continents—Africa, Asia and Europe. They built many new roads and developed the world’s first postal service.
The ancient Persians of the Achaemenid Empire created art in many forms, including metalwork, rock carvings, weaving and architecture. As the Persian Empire expanded to encompass other artistic centers of early civilization, a new style was formed with influences from these sources.
Early Persian art included large, carved rock reliefs cut into cliffs, such as those found at Naqsh-e Rustam, an ancient cemetery filled with the tombs of Achaemenid kings. The elaborate rock murals depict equestrian scenes and battle victories.
Ancient Persians were also known for their metalwork. In the 1870s, smugglers discovered gold and silver artifacts among ruins near the Oxus River in present-day Tajikistan.
The artifacts included a small golden chariot, coins, and bracelets decorated in a griffon motif. (The griffon is a mythical creature with the wings and head of an eagle and the body of a lion, and a symbol of the Persian capital of Persepolis.)
British diplomats and members of the military serving in Pakistan brought roughly 180 of these gold and silver pieces—known as the Oxus Treasure—to London where they are now housed at the British Museum.
The history of carpet weaving in Persia dates back to the nomadic tribes. The ancient Greeks prized the artistry of these hand-woven rugs—famous for their elaborate design and bright colors.
The ancient Persian capital city of Persepolis, situated in southern Iran, ranks among the world’s greatest archeological sites. It was named a UNESCO World Heritage Site in 1979.
The Achaemenian palaces of Persepolis were built upon massive terraces. They were decorated with ornamental facades that included the long rock relief carvings for which the ancient Persians were famous.
Many people think of Persia as synonymous with Islam, though Islam only became the dominant religion in the Persian Empire after the Arab conquests of the seventh century. The first Persian Empire was shaped by a different religion: Zoroastrianism.
Named after the Persian prophet Zoroaster (also known as Zarathustra), Zoroastrianism is arguably the world’s first monotheistic religion. It’s still practiced today as a minority religion in parts of Iran and India.
Zoroaster, who likely lived sometime between 1500 and 500 B.C., taught followers to worship one god instead of the many deities worshipped by earlier Indo-Iranian groups.
The Achaemenian kings were devout Zoroastrians. By most accounts, Cyrus the Great was a tolerant ruler who allowed his subjects to speak their own languages and practice their own religions. While he ruled by the Zoroastrian law of asha (truth and righteousness), he didn’t impose Zoroastrianism on the people of Persia’s conquered territories.
Hebrew scriptures praise Cyrus the Great for freeing the Jewish people of Babylon from captivity and allowing them to return to Jerusalem.
Subsequent rulers in the Achaemenid Empire followed Cyrus the Great’s hands-off approach to social and religious affairs, allowing Persia’s diverse citizenry to continue practicing their own ways of life. This period of time is sometimes called the Pax Persica or Persian Peace.
Fall of the Persian Empire
The Persian Empire entered a period of decline after a failed invasion of Greece by Xerxes I in 480 BC. The costly defense of Persia’s lands depleted the empire’s funds, leading to heavier taxation among Persia’s subjects.
The Achaemenid dynasty finally fell to the invading armies of Alexander the Great of Macedon in 330 B.C. Subsequent rulers sought to restore the Persian Empire to its Achaemenian boundaries, though the empire never quite regained the enormous size it had achieved under Cyrus the Great.
