457 BC
Year 457 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Pulvillus and Augurinus or Cincinnatus and Vibulanus (or, less frequently, year 297 Ab urbe condita). The denomination 457 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Greece
Athens, the leader of the Delian League, comes into conflict with Corinth and its ally Sparta (leader of the Peloponnesian League) over Megara. Nicodemes of Sparta, regent for King Pleistoanax, leads an army of 11,500 hoplites into Boeotia to help Thebes put down a rebellion by Phocis.
Athenian forces block the routes back to the Peloponnese, so the Spartans decide to remain in Boeotia and await the Athenian attack. The Athenians and their allies, with 14,000 men under the command of Myronides, meet the Spartans at Battle of Tanagra. The Spartans win the battle, but they lose many men and so are unable to follow up on their victory.
