Cyrus the Great. The name reverberates through the ancient world
With a distinctive resonance. A conqueror, yes, but also—almost
Uniquely among ancient conquerors—remembered by the conquered
Themselves with gratitude. The Jews called him Yahweh's anointed.
The Babylonians welcomed him as liberator. The Greeks, writing
Generations later, portrayed him as a model of just kingship
(Even as their city-states faced Persian expansion). Cyrus's
Reputation was such that even his successors' failures could not
Erase it. And the empire he founded, the Achaemenid empire, was
The largest the world had yet seen—stretching from the Indus Valley
To the Aegean Sea, from the Caucasus to Egypt's southern border.
Over thirty million people under a single political authority.
Multiple languages, multiple religions, multiple ecological zones,
Multiple histories. The Persian achievement was to hold all this
Together in a functional imperial system for two hundred years.
How did they do it? That is the subject of this chapter.
Cyrus was born around five-ninety BCE in Anshan, in what is now
Southwestern Iran. His father Cambyses I was king of the
Persians, a tributary of the Medes. His mother, by some accounts,
Was the daughter of Astyages, king of the Medes—making Cyrus
A Median prince through his maternal line. The Persians and
Medes were closely related Iranian peoples with shared language
And culture; in the political geography of the early sixth century
BCE, the Medes dominated. Cyrus inherited his father's throne
Around five-fifty-nine BCE and began a remarkable career of
Conquest. He rebelled against Median overlordship around five-
Fifty-three BCE, and within a few years had defeated Astyages
And absorbed the Median kingdom. He then turned westward against
Lydia. King Croesus of Lydia—proverbial for his wealth, and the
Ruler of Anatolia west of the Halys River—had reportedly
Consulted the Oracle of Delphi about whether to make war on
Persia. The oracle's answer was famously ambiguous: "If you
Cross the Halys, you will destroy a great empire." Croesus
Crossed. The empire destroyed turned out to be his own. Cyrus
Defeated him at Thymbra in five-forty-seven BCE and annexed
Lydia, including the Greek-speaking cities of the Ionian coast.
Then he turned east and consolidated his rule over the Iranian
Plateau and Central Asia. Then, finally, in five-thirty-nine BCE,
He marched on Babylon. As noted in the previous chapter, Babylon
Fell with little resistance—the unpopular Nabonidus was deposed,
The Babylonian priests welcomed Cyrus, and the city was
Incorporated into the Persian empire without destruction. Cyrus
Then issued his famous edict permitting exiled peoples to return
To their homelands and rebuild their temples—an edict which
Benefited the Jews most famously but which was in fact a general
Policy. Cyrus wanted his subjects to be grateful, loyal, and
Stable, and he understood that religious and cultural autonomy
Was cheaper than coercion. The Cyrus Cylinder, a clay cylinder
Inscribed with his proclamation on taking Babylon and now held
In the British Museum, is sometimes called the "first charter of
Human rights"—a slightly overheated description, but the cylinder
Does record an explicit policy of religious tolerance and
Restoration of displaced peoples. For its time, this was remarkable.
Cyrus died in battle around five-thirty BCE, fighting against
The Massagetae in Central Asia. His tomb at Pasargadae—a
Simple stone structure surmounted by a gabled roof—still stands
And is one of the most moving monuments of antiquity. Its
Inscription is said to have read: "O man, I am Cyrus the son of
Cambyses, who founded the empire of the Persians and was king
Of Asia. Grudge me not therefore this monument." Simplicity, even
Humility, inscribed on the tomb of a world conqueror.
His son
Cambyses II continued the expansion, conquering Egypt in
Five-twenty-five BCE. The last native Egyptian pharaoh, Psamtik III,
Was defeated at Pelusium and then captured. Cambyses briefly
Ruled Egypt as pharaoh before dying under unclear circumstances
In five-twenty-two BCE. His death triggered a crisis: Cambyses had
Apparently had his own brother Bardiya secretly killed before the
Egyptian campaign, and an impostor claiming to be Bardiya seized
The throne. This impostor was overthrown by a faction of Persian
Nobles led by Darius, a distant relative of the royal family.
Darius became king and spent the next several years putting down
Rebellions across the empire. His account of these events is
Preserved in the Behistun Inscription—a massive rock relief
Carved high on a cliff in western Iran, written in three
Languages (Old Persian, Elamite, and Akkadian) and featuring
Darius himself triumphing over nine defeated rebels. The
Behistun Inscription was what, in the nineteenth century CE,
Allowed scholars to decipher cuneiform—because its trilingual
Structure functioned like the Rosetta Stone did for Egyptian
Hieroglyphics. Without Behistun, our knowledge of ancient
Mesopotamia and Persia would be vastly poorer. Darius, in
Addition to successfully defending his reign, was a brilliant
Administrator. He reorganized the empire into twenty satrapies
(Provinces), each under a satrap (governor) responsible to the
Central government. He established a standardized tax system,
Weights and measures, a royal postal service with relay stations
(The famous "royal roads" with horse stations every day's ride,
Allowing messages to travel from Susa to Sardis in a week), and
A single imperial currency (the gold daric). He built the great
Ceremonial capital at Persepolis, whose ruins still impress
Visitors with their scale and architectural sophistication. The
Apadana audience hall at Persepolis, with its thirty-six
Massive columns rising over twenty meters, was surrounded by
Reliefs showing delegations from all the empire's peoples
Bringing tribute—Medes, Elamites, Babylonians, Egyptians,
Lydians, Ionians, Indians, Scythians, Arabs, and many more.
The imagery was ideological: the Great King ruled many peoples,
And each people brought him its distinctive gifts. Diversity under
A single imperial canopy. The visual rhetoric of Persian rule
Was pluralistic: the king was honored in the distinctive styles
Of each subject culture, and each subject culture retained its
Own traditions under his protection. This was not assimilation
Imperialism. It was federation imperialism. Each people kept its
Language, its religion, its local rulers (often), its cultural
Practices—as long as it paid tribute, provided troops when
Required, and accepted ultimate Persian authority. For most
Subject peoples, Persian rule was much lighter than the rule
Of Assyria or Babylon had been. The Persians did not conduct
Mass deportations. They did not demand religious conformity. They
Taxed regularly and expected loyalty, but they did not terrorize.
And the result was an empire that was, by the standards of the
Time, remarkably stable and prosperous for most of its population.
Darius
Extended the empire further, adding the Indus Valley in the east
And Thrace in the west. He attempted to expand into Greece but
Was defeated at Marathon in four-ninety BCE. Greece would remain
Beyond Persian reach, though the empire retained significant
Greek-speaking territories in Anatolia and Cyprus. Darius died
In four-eighty-six BCE, having reigned for thirty-six years and
Having consolidated the largest empire in history to that point.
His son Xerxes I attempted another invasion of Greece in four-
Eighty BCE, which also failed (after initial success) due to the
Greek naval victory at Salamis and land victory at Plataea.
Xerxes is a complicated figure in the historical record—portrayed
In the Hebrew Bible as Ahasuerus, husband of Esther and
Protagonist of that remarkable novella of Jewish court intrigue;
Portrayed by Herodotus as an arrogant tyrant whose hubris
Brought his army to disaster at Salamis; portrayed in Persian
Inscriptions as a mighty king completing his father's constructions
At Persepolis. Each perspective captures something. Xerxes was
The last of the great conquering Persian kings. After him, the
Empire ceased expanding and focused on maintaining what it had.
Subsequent Achaemenid kings—Artaxerxes I, Darius II, Artaxerxes II,
Artaxerxes III, Arses, Darius III—mostly managed to hold the
Empire together despite periodic rebellions (especially in Egypt,
Which repeatedly revolted and was repeatedly reconquered). Court
Intrigue and succession disputes weakened the central authority
Over time. The empire grew more decadent, more reliant on
Mercenary troops, more dependent on bribery to buy the loyalty of
Its various satraps and subject peoples. By the mid-fourth century
BCE, the Persian Empire was still vast but increasingly hollow.
It would prove vulnerable to the decisive blow that Alexander the
Great would deliver in the following decades—but that is for
A later chapter. For now, we are concerned with the empire as it
Existed during its classical period: vast, diverse, administratively
Sophisticated, and unprecedented in human history for its scale
And its (relative) administrative rationality.
Consider some
Specific features of Persian rule that have had lasting influence.
The Royal Road that ran from Susa to Sardis—some twenty-five
Hundred kilometers, with postal stations at regular intervals—was
The prototype of imperial road systems that would later include
The Roman viae and the Inca Qhapaq Ñan. The idea that an
Empire should have systematic communication and transport
Infrastructure was not obvious; it had to be invented, and the
Achaemenids invented it on a scale nobody had previously attempted.
The satrapy system was the first mature imperial provincial
Administration. Each satrapy had its satrap (civil governor), its
Military commander (deliberately separated from the satrap to
Prevent consolidation of local power), and its royal secretary
(Who reported directly to the central court on the actions of
The other two). This three-way balance of authority prevented
Any single official from accumulating enough power to rebel. The
Roman and later imperial administrations would borrow variations
On this structure. The standardized coinage, weights, and measures
Facilitated trade and commerce across the empire's vast territory.
Economic integration rose to a level that would not be matched
In the region until the early modern period. Cultural contacts
Flourished. Greek doctors and sculptors worked in Persepolis.
Phoenician sailors worked in the Persian navy. Jewish scribes
Worked in the royal court. Indian traders brought goods from the
Ganges to Babylonia. The empire was a zone of exchange in which
Ideas and goods moved across what had previously been separate
Civilizational spheres. Some scholars have argued that the
Persian Empire was the cradle of the first genuinely global
Economy—the first time that commercial networks linked the entire
Old World in sustained exchange. And the cultural consequences
Were profound. The spread of Aramaic as a lingua franca across
The empire. The dissemination of Babylonian astronomy to Greeks
And Indians. The transmission of Zoroastrian religious concepts
Into Jewish thought (as we have already discussed). The mixing of
Artistic styles—Persian architecture shows influences from Egypt,
Mesopotamia, Ionia, and Central Asia, synthesized into its own
Distinctive imperial style. The Persian Empire was not just a
Political unit. It was a cultural matrix through which the
Achievements of multiple civilizations flowed and mixed.
And
The religious dimension is worth returning to. The Achaemenid
Kings were Zoroastrian—or at least their inscriptions invoke
Ahura Mazda and frame their kingship in Zoroastrian terms.
But they did not impose Zoroastrianism on their subjects. In
Babylon, Cyrus participated in the Marduk festival and presented
Himself as Marduk's chosen servant. In Egypt, Cambyses and his
Successors styled themselves as pharaohs and patronized Egyptian
Temples. In Jerusalem, Cyrus permitted the rebuilding of the
Temple and supported it with royal funds. The Persians understood
That religious legitimacy in a multi-ethnic empire required
Adopting the religious forms of each subject culture. This was
Not cynicism; it was genuine imperial theology. Ahura Mazda was
Thought to be the universal creator, whose purposes were served
By the continuance of proper worship wherever it occurred, under
Whatever local name. The Persian king, as Ahura Mazda's agent
In the world, had the duty to support all legitimate cults within
His realm. This theological framework made religious tolerance
Into a positive imperial virtue rather than a pragmatic concession.
And the consequence was that the Persian Empire was, for most
Of its subjects, a religiously comfortable home. It was not
Paradise—there were rebellions, there were failed reconquests,
There were occasional episodes of imperial brutality. But compared
To what had come before, and compared to many empires that would
Follow, the Persian Empire was a relatively humane political
Structure. Its subjects were not, on the whole, eager to be freed
From it. When Alexander conquered the empire in the fourth
Century BCE, he did not find populations widely hostile to their
Existing rulers. He found populations who accepted Persian
Rule as reasonably fair and effective. His conquest had to be
Imposed militarily, not welcomed as liberation. This is itself
A testimony to the quality of Persian governance.
