What this dot point is asking
NESA expects you to survey the Greek mainland and the Persian Empire at the start of the fifth century BC: the rise of Achaemenid Persia under Cyrus, Cambyses, and Darius I; how Persia controlled subject Ionia; the geographical setting and the polis system; the constitutions of Athens (after Cleisthenes) and Sparta; the major leagues and alliances; and the source base, led by Herodotus, that historians use to reconstruct this world before it collided with the mainland Greeks.
The answer
The rise of Achaemenid Persia
The Achaemenid Persian Empire was the largest and most administratively sophisticated state the ancient world had yet seen, and its expansion under three successive kings brought it to the edge of the Aegean just as the Greek world was reshaping its own politics.
- Cyrus the Great (559 to 530 BC)
- Cyrus founded the empire by uniting the Persians and Medes, then conquering the wealthy kingdom of Lydia under Croesus in 546 BC, which brought the Greek cities of Ionia under Persian rule for the first time. He went on to conquer Babylon (539 BC), creating an empire stretching from Asia Minor to Central Asia.
- Cambyses (530 to 522 BC)
- Cyrus's son Cambyses added Egypt to the empire in 525 BC after defeating Pharaoh Psamtik III at Pelusium, extending Achaemenid rule to Nubia's border. His reign ended in a succession crisis, and Darius, a member of a collateral branch of the royal family, seized the throne in 522 BC.
- Darius I (522 to 486 BC)
- Darius consolidated and reorganised the empire rather than merely expanding it. He divided the territory into around 20 satrapies (provinces), each governed by a satrap who collected a fixed tribute, raised troops, and administered justice, while royal inspectors ("the King's Eyes and Ears") and a royal secretary attached to each court reported directly back to the king, a check against any satrap becoming an independent power. Darius standardised coinage (the gold daric), built the royal road (about 2,500 km, Susa to Sardis) with its angareion courier relay described by Herodotus (8.98), and commissioned the Behistun inscription (c. 520 BC), which presents his accession as sanctioned by Ahura Mazda. The elite Persian and Median infantry, the Immortals (10,000 strong), anchored a combined-arms army that also drew cavalry and fleets from subject peoples.
Ionia under Persian rule
The Ionian Greek cities of Asia Minor, the wealthiest and most culturally advanced part of the Greek world, had passed from Lydian to Persian control in 546 BC. Rather than governing each polis directly, the satrap based at Sardis typically installed or confirmed a local Greek as tyrant in each city, a client ruler whose position depended entirely on Persian backing.
These tyrants owed their power to Persia, not to their own citizens: they collected the fixed tribute assessed by the satrapy, supplied troops and (where relevant) ships on demand, and were replaced by the satrap if they proved unreliable. This was a far cheaper way of controlling dozens of scattered poleis than stationing permanent Persian garrisons in each one, but it left the Ionian cities without the kind of internally driven constitutional development under way at Athens, and it created a standing grievance: Greek citizens ruled by a fellow Greek who answered to a foreign king. That grievance would erupt in the Ionian Revolt of 499 BC, when Aristagoras of Miletus, one such client tyrant, turned against his Persian patrons.
The geographical setting
Mainland Greece is mountainous and broken into small fertile plains separated by ranges. The Aegean is studded with islands. This geography reinforced the polis system: hundreds of small independent city-states, each with its own constitution, army, coinage, and patron god. The major regions of 500 BC were Attica (with Athens), the Peloponnese (with Sparta, Corinth, Argos), Boeotia (with Thebes), Thessaly, and the islands. Greek poleis also dotted the coastlines of Asia Minor (Ionia), Sicily, southern Italy, and the Black Sea, the legacy of the colonising movement of the eighth to sixth centuries BC that had spread Greek communities far beyond the mainland in search of land, trade, and resources.
The polis as the basic unit
A polis was a self-governing community of citizens (politai) with a defined territory, an urban centre, and shared religious institutions. By 500 BC there were perhaps 1,000 poleis in the Greek world. They shared a common Greek identity (language, gods, panhellenic sanctuaries at Olympia and Delphi) but no political unity, a fragmentation that would shape, and complicate, the Greek response to Persia.
Athens after Cleisthenes
In 508/7 BC the aristocrat Cleisthenes had reformed the Athenian constitution after the fall of the Peisistratid tyranny in 510 BC.
- Ten new tribes
- Each citizen was assigned to one of ten new tribes (named after Attic heroes), made up of three trittyes (thirds) drawn from coast, plain, and city. This cut across the old regional and aristocratic loyalties.
- The deme
- The local village (deme) was the basic administrative unit. Around 139 demes registered the citizens of Attica. Citizenship was hereditary through the deme.
- The Council of 500 (boule)
- Fifty councillors from each tribe, chosen by lot annually from those over thirty, prepared business for the Assembly. The boule sat in the bouleuterion in the agora.
- The Assembly (ekklesia)
- All adult male citizens could attend, debate, and vote. The Assembly met on the Pnyx hill.
- Ostracism
- A procedure by which the Assembly could exile a citizen for ten years without loss of property or status. Introduced around 508 BC and first used in 487 BC against Hipparchus son of Charmus, a relative of the Peisistratids.
Herodotus (5.66) credits Cleisthenes with the foundation of Athenian democracy. The political system was still developing: archons were elected (not yet selected by lot), and the Areopagus retained extensive powers until Ephialtes reformed it in 462 BC.
Sparta
Sparta was the leading military power on the mainland in 500 BC.
- Dual kingship
- Two hereditary kings, one from the Agiad house and one from the Eurypontid, commanded the army and held religious functions.
- The gerousia
- A council of 28 elders (over sixty) plus the two kings. Members served for life. The gerousia prepared business for the assembly.
- The ephors
- Five magistrates elected annually by the assembly. The ephors had broad powers including supervision of the kings and the management of foreign policy.
- The assembly (apella)
- All Spartiate citizens could attend; voting was by acclamation.
- The helots
- Sparta's economy rested on an enslaved population of Messenians (conquered c. 715 to 668 BC) and Laconians. The helots farmed the land while the Spartiates trained for war. The agoge, the state education system, produced full-time soldier-citizens (homoioi, "the equals").
- The Peloponnesian League
- A network of alliances binding most of the Peloponnese (except Argos and Achaea) to Sparta as hegemon. The League met when Sparta convened it.
Other major mainland states
- Thebes
- The leading Boeotian polis, dominant in the Boeotian League.
- Corinth
- A commercial and naval power on the isthmus.
- Argos
- A traditional rival of Sparta in the Peloponnese.
- Thessaly
- A confederation of aristocratic states in the north.
The Greek east: Ionia and the islands
The Greek cities of Asia Minor (Ionia) had been founded in the migrations of the eleventh and tenth centuries BC. By 500 BC they were the most prosperous and culturally advanced part of the Greek world: home to the philosophers (Thales, Anaximander, Heraclitus), the historians (Hecataeus, later Herodotus from Halicarnassus), and the major poets. Miletus was the largest. The Ionian cities had been subjects of Lydia under Croesus, then of Persia after Cyrus's conquest of Lydia in 546 BC, governed thereafter through client tyrants answering to the satrap at Sardis (see "Ionia under Persian rule" above).
Greek and Persian first contact
Persian expansion reached the Aegean in 546 BC when Cyrus conquered Lydia and inherited the Greek cities of Ionia. By 513 BC Darius had crossed the Bosphorus and campaigned in Thrace and Scythia, bringing Persian power to the edges of Europe. Athens and Eretria sent envoys to Persia around 507 BC seeking an alliance against Sparta; the envoys offered "earth and water" (tokens of submission). On their return the Athenians repudiated the gift, but Persia regarded Athens as a subject.
The sources
Herodotus, Histories, is the principal source for this period, and his strengths, methods, and biases all need to be weighed together. Born at Halicarnassus (a Greek city under Persian influence) around 484 BC, he travelled widely across Egypt, the Levant, and the Black Sea region collecting oral tradition, and Books 1 and 5 cover the rise of Persia and the Cleisthenic reforms respectively. His method often presents competing versions of a story side by side ("some say... others say...") rather than a single flattened account, which is a genuine strength for a modern historian trying to see the seams in the evidence. His limitations are equally real: he worked from oral tradition gathered decades after some events, could not read Persian or cuneiform sources directly, and wrote for a Greek, largely Athenian, audience after the Persian Wars, which shapes his sympathetic treatment of Cleisthenes and his occasionally moralising framing of Persian kings.
- Thucydides, Histories 1.89 to 118 (the Pentecontaetia)
- A dense digression covering the fifty years from 478 to 432 BC, written a generation after Herodotus. It is more analytical and less anecdotal, useful for the transition from the Persian Wars into the growth of Athenian power, though its extreme compression means it often summarises in a sentence what took Herodotus a chapter.
- Plutarch, Lives (early second century AD)
- Biographies such as his Life of Themistocles are written some 500 years after the events they describe, drawing on now-lost earlier historians. They are valuable for anecdote, character, and later reputation, but must be used cautiously as evidence for verified fact from this period.
- The Athenian Constitution (Aristotelian school, c. 330s BC)
- Chapters 20 to 22 cover the Cleisthenic reforms in more technical, less narrative detail than Herodotus.
- Inscriptions
- Ostraka (potsherds bearing names) from the Athenian agora; the Behistun inscription of Darius; Persepolis fortification tablets; and, for the following decades, the Athenian tribute lists, the annual stone-carved quota lists recording payments into the Delian League treasury from 454 BC, which give hard, dated, quantifiable figures no literary source can match.
- Archaeology
- The Acropolis and Agora at Athens; Persepolis; Sardis; the Athenian deme sites.
How to read a source on this topic
Section IV background sources typically include extracts from Herodotus on the Cleisthenic reforms, the Athenian Constitution on the Council of 500, or Persian royal inscriptions. Three reading habits.
First, distinguish the structural background from the narrative. The period 500 to 440 BC is shaped by Persia, Athens, and Sparta as institutions; do not collapse the survey into "the wars started in 490 BC."
Second, watch for Herodotus's Athenian sympathies. He grew up in Persian Halicarnassus but wrote in Athens; the Cleisthenic reforms are presented positively.
Third, integrate the Persian side and the later sources. Persian sources (Behistun, the Persepolis tablets) describe a confident world empire for which Greece was peripheral; Thucydides's Pentecontaetia and the Athenian tribute lists extend and quantify the story into the 450s and 440s BC that Herodotus barely reaches.
Exam-style practice questions
Practice questions written in the style of NESA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Practice (NESA)6 marksDescribe the main features of the Greek world and the Persian Empire at the start of the fifth century BC.Show worked answer →
A 6-mark "describe" needs the polis system, Athens and Sparta, and Achaemenid Persia.
- The polis system
- Greece was divided into around 1,000 independent poleis (city-states) by the mountainous geography of the mainland and the islands. Each polis had its own constitution, army, and patron god. The two leading poleis by 500 BC were Athens (a developing democracy) and Sparta (a militarised oligarchy).
- Athens after Cleisthenes (508/7 BC)
- Cleisthenes had reorganised the citizen body into ten new tribes based on demes (local villages). The Council of 500 (boule), chosen by lot from the tribes, prepared business for the Assembly (ekklesia). Ostracism (introduced around 508 BC, first used 487 BC) allowed the Assembly to exile a citizen for ten years.
- Sparta
- A dual kingship (the Agiad and Eurypontid houses), the gerousia (council of 28 elders plus the two kings), the ephors (five annually elected magistrates), and an assembly of Spartiate citizens. Spartan society rested on the helots, an enslaved population of Messenians and Laconians. The Peloponnesian League bound most of the Peloponnese to Spartan leadership.
- The Persian Empire
- Under Darius I (522 to 486 BC) the Achaemenid empire stretched from the Indus to the Aegean coast, organised into satrapies, with a royal road and a uniform coinage (the daric). The Ionian Greek cities of Asia Minor were Persian subjects after Cyrus's conquest of Lydia in 546 BC.
Markers reward the polis system, Athens and Sparta, and the Achaemenid context.
Practice (NESA)4 marksOutline the Cleisthenic reforms at Athens and their significance.Show worked answer →
A 4-mark "outline" needs the reforms and the consequence.
- Ten new tribes (508/7 BC)
- Cleisthenes replaced the four old Ionian tribes with ten new ones, each made up of three trittyes drawn from coast, plain, and city. This broke up the regional power blocs of the aristocratic families.
- The deme as the basic unit
- Citizenship was registered at the deme (local village). Around 139 demes provided the citizen body.
- The Council of 500 (boule)
- Fifty councillors from each tribe, chosen by lot annually, prepared business for the Assembly. The prytany system rotated executive responsibility through the tribes.
- Ostracism
- Each year the Assembly could vote on whether to ostracise; if it voted yes, the citizen with the most ostraka (potsherds) was exiled for ten years. First used against Hipparchus son of Charmus in 487 BC.
- Significance
- Cleisthenes created the institutional framework of Athenian democracy. Herodotus (5.66 to 78) calls him the founder of isonomia (equality before the law).
Markers reward the tribes, the deme, the boule, and the political consequence.
Practice questions
Original practice questions graded from foundation to exam level, each with a full worked solution. Try them before revealing the solution.
foundation4 marksOutline the structure of the Achaemenid satrapy system established under Darius I.Show worked solution →
A 4-mark "outline" wants several correct, sequenced features with brief development.
- Point 1: The province
- Darius I (522 to 486 BC) divided the empire into about 20 satrapies (provinces), each corresponding roughly to a conquered kingdom or region (e.g. Lydia, Egypt, Babylonia).
- Point 2: The satrap
- Each satrap was usually a Persian noble, often a royal relative, appointed by the king to collect tribute, raise troops, and administer justice in the province.
- Point 3: Checks on the satrap
- Royal inspectors ("the King's Eyes and Ears") and a royal secretary attached to each satrapy reported directly to the king, guarding against a satrap building an independent power base.
- Point 4: Communication and coinage
- The royal road (c. 2,500 km, Susa to Sardis) and the angareion courier system linked the satrapies to the centre; a uniform gold coinage (the daric) and fixed tribute assessments standardised the economic relationship.
Markers reward correct dated detail (Darius, 522 to 486 BC) and each feature developed beyond a single word.
foundation4 marksSource A (ExamExplained reconstruction, illustrative only, not a translated original): a boundary stele of the type set up in an Ionian city under Persian rule, recording that 'the polis submits earth and water to the Great King and confirms [tyrant's name] as its ruler under Persian protection.' Using Source A and your own knowledge, describe how Persia controlled the Ionian Greek cities after 546 BC.Show worked solution →
A 4-mark "describe" using a source needs the source's content plus supporting own knowledge.
Use the source. The reconstructed stele shows two mechanisms working together: the formal token of submission ("earth and water") and the installation of a named local ruler acting "under Persian protection," rather than direct rule by a Persian official alone.
Own knowledge. After Cyrus conquered Lydia in 546 BC, the satrap based at Sardis governed Ionia but relied on client tyrants placed in individual poleis such as Miletus. These tyrants owed their position and their survival to Persian backing, collected tribute for the satrap, and provided troops and ships on demand. This was cheaper and more stable than permanent garrisons in dozens of separate cities.
Markers reward correct use of the source's detail and the named mechanism (client tyranny under satrapal oversight).
core5 marksExplain the significance of the Cleisthenic reforms of 508/7 BC for the development of Athenian democracy.Show worked solution →
A 5-mark "explain" needs the reforms AND why they mattered, not just a list.
- The reforms
- Cleisthenes replaced the four old Ionian tribes with ten new tribes, each combining trittyes from the coast, plain, and city; citizenship was now registered through the local deme (around 139 of them); the Council of 500 (boule), chosen by lot from the tribes, prepared business for the Assembly; ostracism let the Assembly exile a citizen for ten years.
- Why it mattered
- By mixing coastal, inland, and urban trittyes inside each new tribe, Cleisthenes broke the regional power bases that aristocratic families like the Alcmaeonidae and the Peisistratids had relied on, so no single clan or district could dominate a tribe's vote. The deme-based citizenship register created a stable, broad-based political identity independent of birth into an aristocratic clan. The boule and the prytany system gave ordinary citizens direct, rotating administrative experience.
- Qualify it
- Cleisthenes did not create full democracy at a stroke: archons were still elected, not selected by lot, and the aristocratic Areopagus retained wide powers until Ephialtes's reforms of 462 BC. Herodotus (5.66 to 78) nonetheless credits Cleisthenes with founding isonomia (equality before the law), the institutional starting point for what Pericles later broadened.
Markers reward the causal link from mechanism (mixed tribes, sortition) to consequence (broken aristocratic power), not a bare list of institutions.
core6 marksSOURCE ANALYSIS. Source B (ExamExplained paraphrase, illustrative only): Herodotus, in the opening books of the Histories, presents Cyrus the Great's rise as guided by a series of dreams and oracular signs that foretold his destiny to rule over Asia. Assess the usefulness and reliability of Source B for a historian investigating the rise of Achaemenid Persia.Show worked solution →
A 6-mark source-analysis task needs balanced usefulness AND reliability, anchored in origin/motive/audience, plus own knowledge and ideally a historian.
- Origin, motive, audience
- Herodotus (born at Halicarnassus, then under Persian rule, c. 484 BC) composed the Histories in Greek for a Greek audience roughly two generations after Cyrus's death (530 BC), drawing on oral tradition gathered on his travels rather than Persian court records, which he could not read.
- Usefulness
- The passage is genuinely useful for the STORY the Persians and their neighbours told about Cyrus's legitimacy: dream-omens and destiny were a standard way ancient Near Eastern and Greek audiences explained the rise of a great king, so the passage reveals how contemporaries understood royal legitimacy, even where it is not a literal record of events.
- Reliability
- Reliability as a factual account of Cyrus's actual life is limited: Herodotus is writing at second or third hand from oral tradition decades after the events, includes folkloric motifs (the exposed infant destined for greatness) that recur across other ancient traditions, and had reasons (writing for a Greek audience that had just fought Persia) to present the rise of the enemy empire as fated rather than as a series of contingent military and political choices.
- Historian
- As John Gould (Herodotus, 1989) and others note, Herodotus is simultaneously a careful collector of variant traditions (he often states more than one version and lets readers judge) and a storyteller working within Greek narrative conventions, so he is best used as evidence for how the story was told, corroborated wherever possible against the Behistun inscription and Near Eastern administrative texts for the political and military facts.
Markers reward origin/motive/audience analysis, BALANCED usefulness and limitations, and a named historian used as part of the argument.
core5 marksCompare the constitutions of Athens (after 508/7 BC) and Sparta at the start of the fifth century BC.Show worked solution →
A 5-mark "compare" needs matched points of similarity AND difference, not two separate descriptions.
- Similarity: both were oligarchic in origin but institutionally checked
- Athens retained the aristocratic Areopagus and elected (not sortition-selected) archons; Sparta retained the dual hereditary kingship and the gerousia of 28 elders. Neither system in 500 BC was the "radical" democracy of Pericles's day.
- Difference: the base of participation
- At Athens, all adult male citizens (perhaps 30,000 to 40,000) could attend the ekklesia, debate policy, and serve by lot on the boule of 500. At Sparta, the apella of Spartiate citizens (a much smaller, more exclusive body, since Spartiate status depended on completing the agoge and maintaining syssitia contributions) voted only by acclamation on proposals set by the gerousia, with no right to debate.
- Difference: the social base beneath the constitution
- Athenian citizens worked the land themselves or used limited slave labour; Spartan citizens were freed for full-time military training only because the helots (an enslaved Messenian and Laconian population) worked the land, a structural dependence with no Athenian equivalent.
- Difference: external structure
- Athens after Cleisthenes had no formal alliance system in 508 BC; Sparta headed the Peloponnesian League, binding most of the Peloponnese (except Argos and Achaea) to Spartan military leadership.
Markers reward genuinely comparative points (participation, social base, external alliances) rather than a list for each city in turn.
exam20 marksESSAY. Evaluate the usefulness of Herodotus as the principal source for the Greek world and the Persian Empire at the start of the fifth century BC.Show worked solution →
A band-6 essay on source evaluation sustains a judgement, uses specific passages and their limitations, and weaves other sources and historiography. This is a PLAN plus a model paragraph.
- Thesis
- Herodotus is indispensable as the only connected narrative source for this period, uniquely combining first-hand travel observation with access to both Greek and Persian-influenced oral tradition; but his usefulness is qualified by his methods, his patriotic Greek framework, and his distance in time and language from the Persian court, so he must be triangulated against Thucydides, Plutarch, and inscriptions wherever they survive.
- Argument line 1: Unmatched scope and method
- Herodotus (Halicarnassus, c. 484 to c. 425 BC) travelled through Egypt, the Levant, and the Black Sea region and explicitly records competing traditions ("some say ... others say"), a self-conscious method that lets a careful reader see the seams in his evidence, unlike a source that presents only one version. Books 1 and 5 remain the fullest surviving account of Cyrus's rise (559 to 530 BC) and the Cleisthenic reforms (508/7 BC).
- Argument line 2: The limits of oral tradition and language
- Herodotus could not read Old Persian or cuneiform; his account of the Persian court and the satrapal system rests on Greek intermediaries and travellers' reports, decades after the events. The Behistun inscription (c. 520 BC), commissioned by Darius himself, gives a directly contemporary Persian self-presentation that both corroborates the scale of Darius's empire and exposes Herodotus's more distant, occasionally garbled detail on Persian administration.
- Argument line 3: Herodotus's Athenian sympathies and other sources
- Raised in Persian-ruled Halicarnassus but writing largely for an Athenian audience after the Persian Wars, Herodotus's account of Cleisthenes and of Ionia carries a discernible pro-Athenian, anti-tyrant slant. Thucydides's Pentecontaetia (Histories 1.89 to 118), though a brief digression written a generation later, is more austere and analytical and extends the narrative from 478 to 432 BC where Herodotus stops. Plutarch's Lives (early second century AD), for figures such as Themistocles, are far more useful for anecdote and later reputation than for verified fact, written some 500 years after the events from now-lost earlier sources. Inscriptions such as the Athenian tribute lists (the annual quota lists recording payments into the Delian League treasury from 454 BC) supply hard, dated, quantifiable data that no literary source can match, though only for what they were designed to record.
- Historiography
- John Gould (Herodotus, 1989) reads him as an honest inquirer working within the limits of oral method; Detlev Fehling (Herodotus and His "Sources", 1971) argued more sceptically that some citations of sources are literary invention; most current scholarship (e.g. Rosalind Thomas, Herodotus in Context, 2000) sits between these positions, treating Herodotus as a genuine researcher shaped by the oral and rhetorical culture of his time.
- Model paragraph (argument line 3)
- Herodotus's usefulness is nowhere clearer, or more compromised, than in his treatment of Cleisthenes. He credits the reforms of 508/7 BC with founding isonomia, equality before the law, a framing that reads suspiciously like a retrospective origin myth for the democracy that had just triumphed over Persia when Herodotus was writing. Where his narrative can be checked, as in the broad institutional detail of the ten tribes and the deme system, it is corroborated by the later, more technical account in the Aristotelian Athenian Constitution (chapters 20 to 22, c. 330s BC); where it cannot, as in his claims about Cleisthenes's motives, a historian is reading rhetoric as much as record. Fehling's scepticism about invented detail is a useful corrective, but as Thomas argues, it does not require discarding Herodotus so much as reading him as a product of, not merely a witness to, his sources.
- Conclusion
- Herodotus remains the indispensable narrative spine for this period, but "principal" does not mean "sufficient": inscriptions supply the hard data, Thucydides the sober continuation, and Plutarch the later reputation, and a strong answer uses all four to qualify, not simply repeat, Herodotus.
Marker's note: band 6 answers name specific books/chapters (Histories 1, 5.66 to 78; Thucydides 1.89 to 118), weigh Herodotus's strengths against his method and bias, and integrate at least two named modern historians as argument, not decoration. Simply asserting "Herodotus is biased" without evidence caps the response at mid-band.
