The foundation of the Delian League (478 BC): HSC Ancient History

An 8-mark "outline" needs the context, organisation, and aims.

Context

After Mycale (479 BC) and the siege of Sestos (winter 479 to 478 BC) the Hellenic League fleet operated under the Spartan regent Pausanias. His arrogance and rumoured medism at Byzantium discredited Spartan leadership in the eastern Aegean. Sparta recalled him in 478 BC. The Ionian and Aegean allies asked Athens to take command.

Foundation

Aristides "the Just" organised the new league at Delos in 478/7 BC. The treasury was kept at Delos in the temple of Apollo. Delos was the religious centre of the Ionian Greeks and politically neutral.

Organisation

A synod (congress) of allies met at Delos. Each member had one vote. Athens chaired but did not vote separately. The hellenotamiai (treasurers of the Greeks), Athenian officials, assessed and collected the tribute (phoros).

The first assessment

Aristides assessed each member's contribution either in cash (phoros) or in ships and crews. The first total was 460 talents annually (Thucydides 1.96). Athenian assessments were proverbial for fairness.

Aims

The original aim was to continue the war against Persia, to free the Greeks of Asia, and to take revenge for Persian damage (Thucydides 1.96). The League was a Greek alliance under Athenian leadership, not a Persian-style empire.

Membership

Initially around 150 states, mostly Ionian, the Aegean islands, and the Hellespontine and Thracian coasts. The Peloponnesians (Sparta, Corinth, Aegina) did not join.

Markers reward context, the synod and treasury, the assessment of tribute, and the aims.

A 7-mark "describe" needs the campaign, the double battle, and the significance.

Date and commander

Cimon, son of Miltiades, around 466 BC.

The campaign

A Delian League fleet of around 200 triremes sailed against the Persian fleet gathering in Pamphylia (southern Asia Minor) to support a Persian counter-attack.

The naval battle

At the mouth of the Eurymedon river the League fleet attacked and destroyed the Persian fleet (about 200 ships).

The land battle

Cimon then landed his hoplites and attacked the Persian land force in its camp. Plutarch (Cimon 12) reports both battles on the same day.

Significance

Eurymedon was the high point of Delian League success against Persia. Persian power was driven back from the south coast of Asia Minor. Cimon's prestige reached its peak. Athenian assessments were not yet feared by allies; the League looked like a successful anti-Persian alliance. The Peace of Callias (around 449 BC) is sometimes traced to the Eurymedon settlement.

Markers reward the commander, the double battle, and the strategic significance.

A 4-mark "outline" wants several correct, sequenced points with brief development.

Point 1: Pausanias's arrogance

Commanding the Hellenic League fleet after Mycale (479 BC), the Spartan regent Pausanias adopted Persian dress and Persian bodyguards. Thucydides (1.130) describes him as "haughty" and says he "scorned the allies."

Point 2: Suspected medism

At Byzantium, Pausanias released Persian prisoners and reportedly corresponded with Xerxes, fuelling suspicion he sought a Persian marriage alliance and rule over Greece as a client of the King.

Point 3: Sparta's recall and withdrawal

The ephors recalled Pausanias in 478 BC. When Sparta sent Dorcis to replace him, the allies refused to accept a new Spartan commander. Sparta, distracted by helot unrest and reluctant to sustain a distant naval war, withdrew from the eastern Aegean altogether.

Point 4: Kinship and confidence in Athens

The Ionian states, linked to Athens by the tradition of the Ionian migration, and impressed by Athens's naval role at Salamis (480 BC) and Mycale (479 BC), asked Athens to take command instead.

Markers reward correct dated detail (478 BC) and the explicit causal link from Pausanias's conduct to the Athenian invitation.

A 3-mark "significance" question needs more than description; it needs why the choice mattered.

Religious centrality

Delos was the traditional sanctuary of Apollo for the Ionian Greeks, home of the panionian festival, so it carried sacred authority that a purely military headquarters would lack.

Political neutrality

Delos belonged to no major power, so no single member state (including Athens) could claim to physically hold the League's funds by force of territory.

Geographic centrality

Positioned mid-Aegean, Delos was accessible to the Ionian cities, the island states and the Hellespontine members alike, making it a practical meeting point for the synod.

Markers reward identifying all three dimensions (religious, political, geographic) rather than only describing the temple of Apollo.

A 5-mark "explain" with a source needs the ritual's detail USED, plus own knowledge showing what it reveals about intent.

Use the source

The oath's wording, "the same friends and enemies," frames membership as a shared military alliance rather than subjection to Athens. The iron-lumps ritual, an oath meant to last "until the iron should float," was a solemn, permanent commitment, signalling the League was conceived as binding and indefinite, not a short-term coalition.

Own knowledge

This matches Thucydides's account (1.96) of the League's stated aims: to continue the war against Persia, free the Ionian Greeks, and take revenge by ravaging the King's territory. The synod at Delos, with each member (including Athens) holding one vote, reinforced an image of a voluntary alliance of nominal equals, not an empire.

Qualify it

The ritual's language of permanent, equal partnership sits in tension with the reality that Athens alone supplied the hegemon, commanded the fleet and, through the hellenotamiai, controlled the tribute from the outset, an asymmetry that the historiography (Meiggs) sees as the seed of the later transformation to empire.

Markers reward direct use of the source's oath language, correct citation of Thucydides 1.96 and Aristotle Ath. Pol. 23.5, and the qualification linking the oath's language to the League's later transformation.

A 6-mark source-analysis task needs balanced usefulness AND reliability, anchored in origin/motive/audience, plus own knowledge and a named historian.

Origin, motive, audience

[Aristotle]'s Constitution of Athens (Ath. Pol.) is a late fourth-century BC Peripatetic school compilation, drawing on earlier Atthidographic and documentary sources, written as an institutional history rather than a polemic, which gives it a comparatively dry, administrative tone distinct from Thucydides's narrative history.

Usefulness

The source is useful as evidence for how the assessment process was remembered and for the specific figure of 460 talents (Thucydides 1.96 corroborates the total), and for the tradition that Aristides's assessments were seen as scrupulously fair, supporting the picture of a genuinely consensual early League.

Reliability and limitations

Reliability is limited because the work was compiled around 150 years after 478 BC, from sources that may already have idealised Aristides ("the Just") in hindsight, and because "fairness" is a value judgement that cannot be verified against a lost original assessment list. The claim should be corroborated against Thucydides's more sceptical Pentecontaetia narrative, which the Athenian Tribute Lists (extant only from 454 BC) cannot themselves confirm for 478/7 BC.

Historian

Russell Meiggs (The Athenian Empire, 1972) treats the "fair Aristides" tradition as broadly credible for the founding moment but argues the structural asymmetries built in from the start (Athenian hegemon, Athenian hellenotamiai) made the later shift to unfairness and empire almost inevitable regardless of Aristides's personal integrity.

Markers reward origin/motive analysis, BALANCED usefulness and limitations, corroboration with Thucydides, and a named historian used as argument.

A band-6 essay sustains a judgement on "to what extent," marshals specific dated evidence, and weaves historiography. This is a PLAN plus a model paragraph.

Thesis

The League as founded in 478/7 BC was framed, and largely functioned, as a genuine alliance of nominally equal, autonomous states pursuing a shared war aim; but its formal structure already contained the asymmetries, Athenian command, Athenian treasurers, a growing preference for cash over ships, that made the later transformation into empire possible rather than accidental.

Argument line 1: Genuine alliance features

The synod at Delos gave every member, including Athens, one vote (Thucydides 1.97). The oath to have "the same friends and enemies," sealed by sinking iron into the sea (Aristotle, Ath. Pol. 23.5), framed membership as voluntary and permanent partnership. Aristides's first assessment of 460 talents (Thucydides 1.96) was, by ancient tradition, scrupulously fair, and members retained formal autonomy.

Argument line 2: Built-in Athenian asymmetry

Athens alone held the hegemonia: it commanded the fleet, chaired the synod's agenda, and supplied the hellenotamiai, the Athenian officials who assessed and collected the phoros from 478/7 BC. As allies increasingly chose to pay cash rather than supply ships and crews, Athens built and crewed more of the fleet itself, concentrating naval power in Athenian hands from the outset.

Argument line 3: The trajectory made visible by Cimon's campaigns

Early operations, Eion (476 BC), Skyros (c. 475 BC), Eurymedon (c. 466 BC), extended Athenian-led power while member states supplied only tribute. Thucydides (1.98-99) treats the reduction of Naxos (c. 470 BC), the first allied revolt suppressed by the League fleet, as the moment the alliance's voluntary character was first broken by force.

Historiography

Russell Meiggs (The Athenian Empire, 1972) argues the League was "transitional" from its foundation, structurally destined for Athenian domination once assessed contributions replaced ships. G. E. M. de Ste. Croix (The Origins of the Peloponnesian War, 1972) counters that Athenian rule was more popular among ordinary allied citizens than Thucydides's elite-focused narrative suggests, at least in this early phase.

Model paragraph (argument line 2)

Yet equality at the synod table concealed an asymmetry built into the League's machinery from its first meeting. It was Athens, not the synod collectively, that provided the hellenotamiai who assessed and banked the phoros, and Athens whose admirals commanded every allied fleet from Eion in 476 BC onward. As smaller states found it easier to pay 460 talents in cash than to maintain triremes and crews, the League's own success at converting members to money payments quietly transferred naval power into exclusively Athenian hands. Meiggs is right to call this the "seed" of empire: the constitution of 478/7 BC never needed to be broken to produce domination, only exercised as written.

Conclusion

The League was a genuine, initially voluntary anti-Persian alliance, not an empire in 478/7 BC, but its formal asymmetries (Athenian hegemony, Athenian treasurers, the drift to cash) made empire the structurally likely, not merely accidental, outcome.

Marker's note: band 6 answers commit to a verdict on "to what extent," cite Thucydides 1.94-99 and Aristotle Ath. Pol. 23 with precision, and integrate at least two named historians as argument rather than decoration. A chronological retelling of Cimon's campaigns with no judgement caps the response at mid-band.

A 4-mark "explain" wants the campaigns tied back to Thucydides's stated aims (1.96): continuing the war, liberating Ionia, and taking revenge.

Eion (476 BC)

Captured from the Persian commander Boges at the mouth of the Strymon; cleared a Persian garrison from the Thracian coast, directly serving the aim of continuing the war against Persia.

Skyros (c. 475 BC)

Cleared of Dolopian pirates, securing Aegean shipping lanes; less directly anti-Persian but consolidated League control of the sea route.

Eurymedon (c. 466 BC)

A League fleet of around 200 triremes destroyed a similarly sized Persian fleet at the mouth of the Eurymedon river in Pamphylia, then Cimon landed and defeated the Persian land force the same day (Plutarch, Cimon 12). This drove Persian naval power out of the south Asia Minor coast, the clearest fulfilment yet of "revenge" by damaging the King's forces and of "liberation" by freeing nearby Greek cities from Persian threat.

Markers reward explicit linkage of each campaign to a specific 1.96 aim, not just narration of events.
