The ‘period of (almost) fifty years’ between the end of the Persian Wars in Greece in 479 and the beginning of the Peloponnesian War in 431. The term is often applied to the account given by Thucydides 2 at 1. 89–118 of the period from 478 to the early 430s, offered to justify his claim that the truest cause of the Peloponnesian War was Athens' growing power and Sparta's fear of it. The account is brief, selective, and lacking in precise dates.
