By place edit

Persian Empire edit

• Egypt revolts against Persian rule. The Egyptian leader, Inaros, asks Athens for assistance, which is willingly provided as Athens has plans to trade with and colonise Egypt. A force of 200 Athenian triremes, which is campaigning in Cyprus, is immediately ordered to Egypt to render assistance.
• Achaemenes, Persian satrap (governor) of Egypt, is defeated and slain in a battle at Papremis, on the banks of the Nile River, by Egyptian forces.
• The construction of the ceremonial complex of Apadana (the audience hall of Darius I and Xerxes I) in Persepolis is completed.

Greece edit

• The First Peloponnesian War breaks out between the Delian League (led by Athens) and a Peloponnesian alliance (led by Sparta), caused in part by Athens' alliance with Megara and Argos and the subsequent reaction of Sparta. The Athenians have built long walls for the Megarans to their port at Nisaea, thereby earning the enmity of Megara's old rival Corinth.
• Argos rises against Sparta. Athens supports Argos and Thessaly. The small force that is sent by Sparta to quell the uprising in Argos is defeated by a joint Athenian and Argos force at Oenoe. (Battle of Oenoe)

Roman Republic edit

• Conflicts arise between the Roman patricians and plebeians. There is also a revolt by Rome's slaves. During the revolt, the Campidoglio is held by the slaves for a lengthy period, along with the most important temples of Rome. It is during this revolt that consul Publius Valerius Publicola dies. The revolt only ends with the arrival of an army from Tusculum, led by Tusculan dictator Lucius Mamilius. Meanwhile, Lucius Quinctius Cincinnatus is appointed as consul to replace Publicola.

Siculi edit

• Ducetius, a Hellenised leader of the Siculi, an ancient people of Sicily, takes advantage of the confusion that follows the collapse of the tyranny in Syracuse and other Sicilian states. With the support of the Syracusan democracy, he drives out the colonists of the former tyrant Hieron from Catana and restores it to its original inhabitants.
