This article concerns the period 359 BC – 350 BC.

• The Macedonian King Perdiccas III is killed while defending his country against an Illyrian attack led by King Bardylis. He is succeeded by his infant son, Amyntas IV. The child's uncle, Philip II, assumes the regency.^[1]
• The Illyrians prepare to close in, the Paeonians raid from the north and two claimants to the Macedonian throne are supported by foreign powers. Philip II buys off his dangerous neighbours and, with a treaty, cedes Amphipolis to Athens.

• Artaxerxes III ("Ochus") succeeds Artaxerxes II as King of Persia and restores central authority over the Persian empire's satraps. To secure his throne he puts to death most of his relatives.

• Alexander of Pherae, Despot of Pherae in Thessaly is murdered by his wife's brother at her instigation.
• Cersobleptes, in conjunction with his brothers, Amadocus II and Berisades, inherits the dominions of the Thracian king, Cotys I, following his murder. However, the overall management of Thracian affairs is assumed by the Euboean adventurer, Charidemus, who is connected by marriage with the royal family, and who plays the prominent part in the ensuing negotiations with Athens for the possession of the Thracian Chersonese.

• Philip II of Macedonia invades the hill tribes of Paeonia and decisively beats them.^[2]

• The Romans defeat the Volsci, annex most of their territory, and settle it with Roman colonists. The Romans also force the Latin League to renew its close alliance with Rome, an alliance which was weakened by Rome’s defeat at the hands of the Gauls in 390 BC.

• Rhodes falls to the Persian satrap Mausolus of Halicarnassus.

See Purim

• Euboean mercenary Charidemus recaptures the Thracian Chersonese for Athens. He receives, from Athens, a golden crown for his part in the victory.^[3]

• The Macedonian general, Parmenion, wins a great victory over the Illyrians. King Philip II of Macedon, having disposed of an Illyrian threat, occupies the Athenian city of Amphipolis (which commands the gold mines of Mount Pangaion). Philip II now has control of the strategic city which secures the eastern frontier of Macedonia and gives him access into Thrace.
• Philip II of Macedon marries Olympias, the Molossian princess of Epirus thus helping to stabilize Macedonia's western frontier.

• The brother-in-law of Dionysius I, Dion, exiled from Syracuse in 366 BC by Dionysius II, assembles a force of 1,500 mercenaries at Zacynthus and sails to Sicily. Dion wrests power from the weak Dionysius II, who is exiled and flees to Locri.

• Having blamed their defeats to Philip II in Thessaly and Chalcidice on his colleagues (Iphicrates and Timotheus), Chares is left in sole command of the Athenian fleet. Chares, in need of money for his war effort, frowns upon asking it from Athens, so, partly compelled by his mercenaries, he enters the service of the insurgent Achaemenid satrap of Phrygia Artabazus who rewards Chares very generously.^[4]
• Artabazus is also supported by the Thebans, who send him 5,000 men under one of their generals Pammenes. With the assistance of these and other allies, Artabazus defeats his Achaemenid enemies in two great battles.^{[citation needed]}
• The Achaemenid King Artaxerxes III orders all the satraps (governors) of his empire to dismiss their mercenaries. The Athenians, who have originally approved their mercenaries' collaboration with Artabazus of Phrygia, order them to leave due to their fear of Achaemenid support for the rebellion of Chios, Rhodes, and Cos. Thebes follows suit and withdraws its mercenaries.
• With King Artaxerxes III succeeding in depriving Artabazus of his Athenian and Theban allies, Artabazus is defeated by the Persian King's general, Autophradates.^{[citation needed]}

• Philip II of Macedon secretly offers the city of Amphipolis back to the Athenians in exchange for the valuable port of Pydna. Despite the Athenians being willing to comply, both Pydna and Potidaea are conquered by the Macedonians (along with other Athenian strongholds in Thessaly and Chalcidice) despite being defended by Athenian forces led by general and mercenary commander, Chares, as well as generals Iphicrates and Timotheus.^{[citation needed]}
• With Pydna and Potidaea occupied, Philip II decides to keep Amphipolis anyway. He also takes the city of Crenides from the Odrysae and renames it Philippi.^{[citation needed]}
• The Phocians capture and sack Delphi in whose territory the famous temple and oracle stand. A sacred war is declared against them by the other members of the Great Amphictyonic League. The Phocians, led by two capable generals, Philomelus and Onomarchus, use Delphi's riches to hire a mercenary army to carry the war into Boeotia and Thessaly.^{[citation needed]}
• The Social War begins between the Second Athenian League, led by Athens, and its revolting allies of Chios, Rhodes, and Kos as well as the independent state Byzantium. Mausolus, the tyrant of Caria, instigates the rebellion against the Athenian control of these states. The revolting allies ravage the islands of Lemnos and Imbros which are loyal to Athens.^[4]
• The Athenian generals Chares and Chabrias are given command of the Athenian fleet with the aim of defeating the rebellious cities. However, Chabrias' fleet is defeated and he is killed in its attack on the island of Chios, off the coast of Ionia.^{[citation needed]}
• Chares is given sole command of the Athenian fleet and withdraws to the Hellespont to move against Byzantium. The generals Timotheus, Iphicrates and his son Menestheus are sent with 60 ships to help him when the enemy fleet is sighted on the Hellespont. Timotheus and Iphicrates refuse to engage due to a severe gale, but Chares does engage and lose many of his ships. Timotheus and Iphicrates are accused by Chares and put on trial, however only Timotheus is condemned to pay a fine.^[4]

• Gaius Marcius Rutilus is the first plebeian to be chosen as a dictator in Rome.^[5]

• With his reforms initiated in this year, the Chinese prime minister Shang Yang starts to transform the once marginal and frontier State of Qin to become the most dominant military force amongst the Warring States of China by the 3rd century BC.^{[citation needed]}

• July 21 (traditional date) – The Temple of Artemis at Ephesus is burned down by a madman named Herostratus, destroying one of the Seven Wonders of the World. The great temple was built by Croesus, king of Lydia, in about 550 BC and was famous not only for its great size (110 metres by 55 metres), but also for the magnificent works of art that adorned it.^{[citation needed]}

• King Artaxerxes III of Persia forces Athens to conclude a peace which requires the city to leave Asia Minor and to acknowledge the independence of its rebellious allies.
• King Archidamus III of Sparta supports Phocis against Thebes in the "Sacred War".
• Chares' war party in Athens is replaced by one under Eubulus which favours peace. Eubulus restores the economic position of Athens without increasing the burden of taxation and improves the Athenian fleet while its docks and fortifications are repaired.

• Reflecting the growing level of discontent with his tyrannical conduct, Dion is assassinated by Callippus, an Athenian who has accompanied him on his expedition to take over as tyrant of Syracuse. Dionysius II remains in exile in Italy.
• Athens recognises the independence of Chios, Kos and Rhodes and makes peace with Mausolus of Caria.
• The Phocians suffer a defeat in the Sacred War against Athens.
• Philip II of Macedon takes and destroys Methone, a town which has belonged to Athens. During the siege of Methone, Philip loses an eye.

• Rome allies itself with the Samnites and they agree on a mutual defence pact.^[6]

• Rome defeats the Etruscans of the city of Caere.

• The State of Qi is victorious over the State of Wei in the Battle of Guiling, a conflict which involves the military strategy of Sun Bin.

• The Mausoleum at Halicarnassus in Caria, the tomb of King Mausolus and one of the Seven Wonders of the World, is built.

• Mausolus, King and Persian satrap of Caria, dies and is succeeded in 352 BC by Artemisia, his sister and wife.^[7]

• The Phocians threaten Thessaly to their north. Philip II of Macedon saw his opportunity to penetrate south.^[8]
• Clearchus, the tyrant of Heraclea, a Greek city on the Black Sea, is murdered by some of the city's citizens led by Chion after a reign of twelve years. Most of the conspirators are killed by the tyrant's body-guards upon the spot, while others are captured and put to death. Within a short time, the city falls under the rule of the new tyrant Satyrus, Clearchus' brother.

• After two initial efforts, Philip II of Macedon drives the Phocians south after a major victory over them in the Battle of Crocus Field. Athens and Sparta come to the assistance of the Phocians and Philip is checked at Thermopylae. Philip does not attempt to advance into central Greece with the Athenians occupying this pass. With this victory, Philip accrues great glory as the righteous avenger of Apollo, since the Phocian general Onomarchos has plundered the sacred treasury of Delphi to pay his mercenaries. Onomarchos' body is crucified, and the prisoners are drowned as ritual demanded for temple-robbers.
• Philip then moves against Thrace. He makes a successful expedition into Thrace, gaining a firm ascendancy in the country, and brings away a son of Cersobleptes, the King of Thrace, as a hostage. Philip II's Thessalian victory earns him election as president (archon) of the Thessalian League.

• Encouraged by a failed effort at invasion of Egypt by King Artaxerxes III, Phoenicia and Cyprus revolt against Persia.

• Demosthenes tries to get the Athenians to cease depending on paid mercenaries and return to the old concept of a citizen army. He also delivers his First Philippic, warning Athenians of the folly of believing that Philip's ill health will save Athens from the Macedonians. In response, Athens' citizens vote for increased armaments.

• Idrieus, the second son of Hecatomnus, succeeds to the throne of Caria on the death of Artemisia II, the widow of his elder brother Mausolus. Shortly after his accession, at the request of the Persian king, Artaxerxes III, Idrieus equips a fleet of 40 triremes and assembles an army of 8,000 mercenary troops and despatches them against Cyprus, under the command of the Athenian general Phocion.
