Abstract
Thucydides, Diodorus and Plutarch describe the outbreak of war between Miletus and Samos in 441/440 b.c.e., ostensibly over possession of their smaller neighbour Priene, in similar ways. What began as a local conflict over land escalated when Miletus appealed to Athens as hegemon of the Delian League. The Athenians ordered arbitration to resolve the conflict, but the Samians, probably concerned that the Athenians would side with the Milesians, refused, which in turn led to war between Samos and Athens. Eight months later a coup at Samos started another war. When the Samians finally surrendered, the Athenians forced them to repay the cost of the siege and collected hostages.
