Cyrus the Great — Founder of the Persian Empire
Founder of the Achaemenid Persian Empire, the largest empire the world had yet seen. Cyrus conquered Media, Lydia, and Babylon in under two decades, then governed through satrapies and a policy of local religious tolerance recorded in the Cyrus Cylinder, a rule later writers from the Hebrew Bible to Greek historians treated as a model of enlightened kingship.
Timeline
Birth and Ancestry
Cyrus was born to Cambyses I, king of the Persian vassal state of Anshan, and Mandane, a daughter of the Median king, if the account of Herodotus is followed. His exact birth year is uncertain, and ancient sources also preserve a legend of his near-death in infancy ordered by his Median grandfather.
Location: Anshan, Persis (Fars), Iran
King of Anshan
Cyrus succeeded his father as king of Anshan, ruling a small Persian realm under the overlordship of the Median Empire. Within a decade he would transform this inheritance into the core of a world empire.
Location: Anshan, Persis
The Fall of the Median Empire
Cyrus rebelled against his grandfather Astyages and captured the Median capital Ecbatana, as confirmed by the contemporary Nabonidus Chronicle. The victory absorbed the Median army and empire, giving Cyrus control of the Iranian plateau.
Location: Ecbatana, Media
The Conquest of Lydia
After the Lydian king Croesus attacked Persian territory, Cyrus defeated him and took the capital Sardis, according to the Babylonian Chronicle (the exact year is debated among scholars). The conquest added western Anatolia, including the Greek cities of Ionia, to the new empire.
Location: Sardis, Lydia (Anatolia)
The Conquest of Babylon
Cyrus's army entered Babylon in October 539 BC with little resistance after defeating Nabonidus at Opis, taking the ancient metropolis and its empire. The conquest transferred Mesopotamia, Syria, and the Levant to Persian rule and made Cyrus master of the largest empire in history to that time.

The Cyrus Cylinder and the Return of the Exiles
A foundation cylinder in Babylonian script presented Cyrus as chosen by Marduk and announced the restoration of displaced peoples and their cults. Consistent with this policy, an edict recorded in the Hebrew Bible allowed the Judean exiles to return to Jerusalem and rebuild their Temple, a decree that made Cyrus a rare foreign ruler praised in scripture.
Location: Babylon
Death and Tomb at Pasargadae
Cyrus died in 530 BC while campaigning on the northeastern frontier against the Massagetae, according to Herodotus, and was succeeded by his son Cambyses II. His tomb at Pasargadae, a modest stepped chamber on a six-course plinth, still stands, and was visited and honored by Alexander the Great two centuries later.
Location: Central Asia / Pasargadae, Persis
The Achaemenid Model of Empire
Cyrus bequeathed a governing system his successors extended: provinces under satraps, respect for local laws and religions, an imperial road and courier system, and administrative use of the Elamite and later Aramaic languages. This model of layered tolerance and delegation influenced imperial governance from Alexander to Rome.
The Cylinder Rediscovered
The Cyrus Cylinder was excavated at Babylon in 1879 by Hormuzd Rassam and entered the British Museum collection. In the twentieth century it was promoted, including by the last Shah of Iran, as an early charter of human rights, a reading contested by modern scholars who identify it with a long Mesopotamian tradition of royal legitimation while acknowledging its unusual policy of restoration.
