Year 350 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Laenas and Scipio (or, less frequently, year 404 Ab urbe condita). The denomination 350 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.

Events

By place

Persian Empire

• Sidon, the centre of the revolt against Persia, seeks help from its sister city of Tyre and from Egypt but gets very little.
• 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.
