✅ Answers
- In 478 BC, after the Persian Wars, Greek states formed a defensive alliance against further Persian attack. Athens was chosen as leader (hegemon) because of its large navy. Members contributed ships or money to a common treasury on Delos.
- Athens moved the treasury from Delos to Athens (454 BC), claiming it was safer. It forced members to use Athenian currency and weights, required legal cases to be tried in Athenian courts, and prevented members from leaving by force (e.g. crushing the Naxos revolt). The Erythrae decree shows Athens directly controlling allied governments.
- They were forcibly prevented. Naxos was the first to attempt withdrawal (c. 470 BC) and was besieged and forced back into the League. Thasos revolted (465 BC) and after a two-year siege was forced to dismantle its walls, surrender its fleet and pay increased tribute. These examples deterred other rebellions.
- After moving the treasury to Athens, Pericles used tribute money to fund the Athenian building programme (including the Parthenon), pay for the navy and support Athenian democracy. Effectively, Athens spent allied money on its own city, provoking resentment.
- It symbolised and enabled the transformation from alliance to empire. The money was now under Athens' direct control. Athens could use the funds for its own purposes rather than just defence against Persia. It also meant Athens could monitor and control contributions more closely.
🧭 Spec Focus — OCR
OCR GCSE Ancient History (J198). Two written papers, no coursework: one covering the Greek world (Persia and Greece, Alexander) and one covering Rome (kings to emperors, Britain). These pages map onto that split: ah-persian-wars, ah-greece and ah-alexander-style period topics for the Greek paper; ah-rome-republic, ah-rome-emperors and ah-britain for the Roman paper. Source-analysis skill is the assessed differentiator — every answer should cite the ancient evidence by author.
🎯 Exam Tips
- Delian League = alliance (478 BC) then empire (by 450s BC)
- Moving treasury to Athens (454 BC) = key turning point
- Naxos and Thasos = examples of Athens crushing revolts
- Tribute funded the Parthenon and Athenian navy

⚠️ Common Errors
✗ The Delian League was always an Athenian empire ✓ The League began as a genuine voluntary alliance against Persia. The transformation into empire was gradual, through a series of steps over about 25 years (478-454 BC)
✗ All League members paid tribute in money ✓ Some members contributed ships instead of money. Over time, most states chose to pay money rather than provide ships, which suited Athens because it kept the navy under Athenian control
✗ Athens controlled the League through elected representatives ✓ Athens controlled the League through military force, not representative institutions. There was no League assembly or council where allies could vote on policy
✍️ Model Answer
Full-Mark Response
Explain how the Delian League was transformed from a defensive alliance into the Athenian Empire. [6 marks]
The Delian League was founded in 478 BC as a voluntary defensive alliance against Persia, with Athens as hegemon (leader) due to its naval supremacy. Members contributed ships or money (phoros) to a common treasury on Delos. The transformation into empire was gradual. First, Athens began treating the League as permanent rather than temporary, even after the Persian threat diminished. When Naxos attempted to withdraw (c. 470 BC), Athens besieged it and forced it back, establishing the principle that membership was compulsory. Thasos suffered the same fate (465 BC) after a two-year siege. Second, most allies chose to pay money rather than provide ships, inadvertently handing naval control entirely to Athens. Third, the crucial turning point came in 454 BC when Athens moved the treasury from Delos to Athens, claiming it needed better security. This gave Athens direct control of League finances. Tribute was then used to fund Athenian building projects (the Parthenon) and the navy, rather than solely for collective defence. Fourth, Athens imposed increasing controls: the Erythrae decree shows Athens dictating allied governments' legal systems; Athenian coinage and weights were made compulsory; important legal cases had to be tried in Athenian courts. By the 440s BC, what had been a voluntary alliance was clearly an empire, with allies as subjects paying tribute to an Athens that controlled their foreign policy, legal systems and economies.
