These questions ask you to connect events, people, and dates within one long conflict. Build a chain of causes and reversals instead of memorising each episode as an isolated label.
Follow the balance of power
Begin with the opposing systems. Sparta led the Peloponnesian League and was strongest in hoplite warfare on land. Athens led a maritime coalition, protected its city and port with the Long Walls, and depended on its fleet. Pericles therefore brought people from the Attic countryside behind the fortifications and avoided staking Athenian survival on an open land battle. This strategy preserved Athens from Spartan invasions of Attica, but crowding inside the city worsened the human setting of an epidemic that killed Pericles; historians cannot identify the disease with certainty.
| Stage | What changed |
|---|---|
| Early war | Spartan armies invaded Attica while Athens used walls and sea power; at Pylos and Sphacteria in 425 BCE, Athenians captured more than one hundred Spartan citizens. |
| Unstable pause | The Peace of Nicias in 421 BCE interrupted fighting but did not resolve the rivalry, so major warfare resumed. |
| Sicilian crisis | The expedition of 415–413 BCE ended near Syracuse with the main Athenian forces destroyed or captured. |
| Naval reversal | Persian money helped Sparta build and maintain a fleet; Lysander then destroyed or seized most of the Athenian fleet at Aegospotami in 405 BCE. |
| Defeat and rule | Athens surrendered in 404 BCE, lost most ships, and demolished the Long Walls. Sparta then supported the brief oligarchy known as the Thirty Tyrants. |
Use three checks when choosing a statement. First, place it before, during, or after the temporary peace. Second, ask whether it fits the land strength of Sparta or the maritime strength of Athens at that stage. Third, prefer measured historical language: an epidemic can be securely placed without claiming a certain diagnosis, and a peace can pause a war without permanently settling it.
Where the story is easily reversed
| Trap | How to reject it |
|---|---|
| Moving the war into the Persian Wars or Alexander's reign | Keep the outer dates, 431 and 404 BCE, around the whole narrative. Alexander belongs to a later Macedonian period, while Persia entered this conflict as a later financial supporter of Sparta, not as the original commander of both coalitions. |
| Swapping the early strategies | Match resources to policy: Spartan pressure came mainly by land, while Athens sheltered behind connected walls and used ships. Sending Athenians into open country for an immediate hoplite decision contradicts Pericles's defensive logic. |
| Turning a striking loss into a complete triumph | Preserve what makes each episode distinctive. Spartan citizens were captured rather than all killed at Sphacteria; Athens failed catastrophically rather than conquering Sicily; surrender removed ships and fortifications rather than leaving them intact. |
| Reversing commander, allegiance, or regime | Lysander commanded Sparta's fleet, so Aegospotami cannot become an Athenian victory. After surrender, Sparta backed a short-lived oligarchy in Athens, not an unrestricted restoration of the citizen Assembly or a Persian monarchy. |
