Cyrus the Great
In twenty years he took Media, Lydia and Babylon and built the largest empire the world had yet seen. What made it last was not the conquest but the settlement: local law, local gods, local elites — an empire governed by consent where its rivals governed by deportation.
Who was Cyrus the Great?
Cyrus II — Kūruš in Old Persian, Kourosh in modern Persian — was the founder of the Achaemenid Empire and its king from roughly 559 to 530 BCE. Born to the small vassal kingdom of Anshan in what is now Fars, he overthrew his Median overlord Astyages around 550 BCE, absorbed the Lydian kingdom of Croesus in 547–546 BCE, and entered Babylon in October 539 BCE. At his death the empire ran some 5,000 kilometres from the Aegean coast to the edge of Central Asia and held perhaps a sixth of the world's population.
His lasting significance is administrative and ethical rather than purely military. Where the Assyrians had ruled by mass deportation and the erasure of local cults, Cyrus restored temples, returned deported communities and their sacred images to their homelands, and left existing legal and religious institutions intact. That policy is recorded in his own words on the Cyrus Cylinder, and independently in the Hebrew Bible.
Twenty years that made an empire
| Date | Event | Consequence |
|---|---|---|
| c. 559 BCE | Accession as king of Anshan | A Persian vassal within the Median confederation |
| c. 550 BCE | Defeat of Astyages of Media at Pasargadae | Median empire absorbed; Ecbatana becomes a Persian capital |
| 547–546 BCE | Campaign against Croesus of Lydia; fall of Sardis | Persian rule reaches the Aegean and the Ionian Greek cities |
| c. 545–540 BCE | Eastern campaigns — Bactria, Sogdiana, Gandhara | Frontier pushed to the Oxus and the Hindu Kush |
| 12 October 539 BCE | Battle of Opis; Babylon entered without a siege | The Neo-Babylonian Empire ends; Mesopotamia becomes Persian |
| 538 BCE | Decree permitting the Judean return | Rebuilding of the Jerusalem Temple begins |
| c. 530 BCE | Death on the north-eastern frontier | Succession of his son Cambyses II |
"He ruled over these nations, though they did not speak the same language as he, nor one nation the same as another; yet he was able to extend the fear of himself over so great a part of the world that he astonished all."
The Cylinder and the policy behind it
The Cyrus Cylinder is a barrel-shaped clay document, about 22 cm long, excavated at Babylon in 1879 and now in the British Museum. Written in Akkadian cuneiform in the established idiom of Babylonian royal proclamations, it presents Cyrus as chosen by Marduk to end the impieties of Nabonidus, and records that he returned cult images to their sanctuaries and allowed displaced peoples to go home.
Two readings compete. The popular one, promoted from the 1960s and reinforced by the replica displayed at the United Nations, calls it the first charter of human rights. The scholarly one — argued most clearly by Amélie Kuhrt — reads it as a conventional Mesopotamian accession text whose content nonetheless reflects a real and unusual imperial policy. Both agree on the substance: restoration in place of deportation.
How the empire was actually run
Cyrus's settlement, refined by Darius I a generation later, established the machinery every subsequent Iranian empire reused: a provincial governor (satrap) drawn where possible from the local aristocracy, a separate military commander and royal secretary as checks on him, fixed tribute in place of arbitrary plunder, and imperial roads with relay stations carrying the king's correspondence.

The tomb, and what came after
Cyrus built his capital at Pasargadae on the Morghab plain: a dispersed royal park of pavilions, watercourses and gardens — the earliest known chahar bagh, ancestor of every Persian garden. His tomb stands there still, a gabled limestone chamber on six receding steps, deliberately modest beside the later terraces of Persepolis. Alexander of Macedon, who had it restored after finding it plundered in 324 BCE, is said to have treated the visit as an act of homage.
The dynasty Cyrus founded ruled for two more centuries. His memory outlasted it: Xenophon made him the model prince of the Cyropaedia, a text read by Machiavelli, Montesquieu and Jefferson, who owned two copies. In Iran the tomb remains a place of gathering, and his name a shorthand for rule without cruelty.
