Year 480 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Vibulanus and Cincinnatus (or, less frequently, year 274 Ab urbe condita). The denomination 480 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
Events
By place
Greece
May – King Xerxes I of Persia marches from Sardis and onto Thrace and Macedonia.
The Greek congress decides to send a force of 10,000 Greeks, including hoplites and cavalry, to the Vale of Tempe, through which they believe the Persian army will pass. The force includes Lacedaemonians led by Euanetos and Athenians under Themistocles. Warned by Alexander I of Macedon that the vale can be bypassed elsewhere and that the army of Xerxes is overwhelming, the Greeks decide not to try to hold there and vacate the vale.
August 20 or September 8-10 – The Battle of Thermopylae ends in victory for the Persians under Xerxes. His army engulfs a force of 300 Spartans and 700 Thespiae under the Spartan King, Leonidas I. The Greeks under Leonidas resist the advance through Thermopylae of Xerxes' vast army. For two days Leonidas and his troops withstand the Persian attacks; he then orders most of his troops to retreat, and he and his 300-member royal guard fight to the last man.
King Alexander I of Macedon is obliged to accompany Xerxes in a campaign through Greece, though he secretly aids the Greek allies. With Xerxes' apparent acquiescence, Alexander seizes the Greek colony of Pydna and advances his frontiers eastward to the Strymon, taking in Crestonia and Bisaltia, along with the rich silver deposits of Mount Dysorus.
August – The Persians achieve a naval victory over the Greeks in an engagement fought near Artemisium, a promontory on the north coast of Euboea. The Greek fleet holds its own against the Persians in three days of fighting but withdraws southward when news comes of the defeat at Thermopylae.
September 22 – The Battle of Salamis brings victory to the Greeks, whose Athenian general Themistocles lures the Persians into the Bay of Salamis, between the Athenian port-city of Piraeus and the island of Salamis. The Greek triremes then attack furiously, ramming or sinking many Persianvessels and boarding others. The Greeks sink about 200 Persianvessels while losing only about 40 of their own. The rest of the Persian fleet is scattered, and as a result Xerxes has to postpone his planned land offensives for a year, a delay that gives the Greek city-states time to unite against him. Aeschylus fights on the winning side.
An eclipse of the sun discourages the Greek army from following up the victory of Salamis. Xerxes returns to Persia leaving behind an army under Mardonius, which winters in Thessaly.
Rome
The Romans achieve a significant victory against Veii after a close-fought battle. Tensions between the Roman classes flare during the battle. Quintus Fabius and the consul Manlius perish in the fighting.
Xerxes encourages the Carthaginians to attack the Greeks in Sicily. Under the Carthaginian military leader, Hamilcar, Carthage sends across a large army.
The Greek city of Himera in Sicily, in its quarrel with Akragas, enlists Carthaginian support. With the help of Gelo, the tyrant of Syracusae, and Theron of Akragas, the Carthaginians are defeated in the Battle of Himera. After the defeat, Hamilcar kills himself.
Persian empire
The Imperial treasury at the Persepolis Palace is completed after a building time of thirty years.
