50 free Peloponnesian War trivia questions with answers — history quiz, new questions added Aug 2026.
The Peloponnesian War set Athens and its Delian League against Sparta and the Peloponnesian League from 431 to 404 BC. It began with Thebans attacking Plataea and Spartan kings marching into Attica, was reshaped by a plague that killed Pericles and a third of Athens, swung to Athens at Sphacteria, paused with the Peace of Nicias, and then broke Athens in Sicily and at Aegospotami once Persian gold built Lysander a fleet. Thucydides, exiled for losing Amphipolis, wrote it all down — until his text stops in 411 BC and Xenophon picks up the thread. This quiz covers the causes — Corcyra, Potidaea, the Megarian decree and the debate at Sparta — the Archidamian War and the Long Walls, Cleon and Brasidas, Mantinea, the massacre at Melos, the mutilated herms, Alcibiades's defections, the fortification of Decelea, the Four Hundred, Cyzicus and Arginusae, the Thirty Tyrants and the symbolic peace the mayors of Athens and Sparta finally signed in 1996.
