Events[edit]

309 BC

By place[edit]

Asia Minor[edit]
  • Ptolemy personally commands a fleet that captures the coastal regions of Lycia and Caria from Antigonus.
Greece[edit]
  • Cassander, who has held Roxana, widow of Alexander the Great, in prison for a number of years, has her put to death along with her young son Alexander, the nominal King Alexander IV of Macedon.
  • Antigonus attempts to renew his alliance with the Macedonian general and former regent Polyperchon, who still controls part of the Peloponnesus. He sends Heracles, the illegitimate son of Alexander the Great, to Polyperchon to be treated as a pretender to the throne of Macedonia.
  • Polyperchon manages to form an army consisting of 20,000 infantry and 1,000 cavalry and challenges Cassander's army. Instead of fighting, Cassander starts negotiations with Polyperchon. By offering to make him a general of his own army and placing him as governor of Peloponnesus, he convinces Polyperchon to change allegiance to him instead of Heracles. As a result Polyperchon murders Heracles and his mother Barsine.
  • Areus I succeeds his grandfather Cleomenes II as king of Sparta.
  • A census is carried out in Athens. 21,000 citizens, 10,000 foreign residents and 400,000 others – women, children and slaves – are living in the city.
Carthage[edit]
  • Since 480 BC, an aristocratic Council of Elders has effectively ruled Carthage. The titular king of Carthage, Bomilcar, attempts a coup to restore the monarchy to full power. His attempt fails, which leads to Carthage becoming in name as well as in fact a republic.
  • Leaving his brother Antander to continue the defence of Syracuse, Agathocles lands in North Africa with the aim of distracting the Carthaginians from their siege of Syracuse. Agathocles concludes a treaty with Ophellas, ruler of Cyrenaica. He then takes advantage of the civil unrest in Carthage and nearly succeeds in conquering the city.
Roman Republic[edit]
China[edit]
  • Soon after the State of Qin has conquered the State of Shu (in modern-day Sichuan province), they employ the Shu engineer Bi Ling to create the Guanxian irrigation system, which will eventually provide for over five million people in an area of 40 to 50 square miles (130 km2), still in use today.

By place[edit]

Cyprus[edit]
Syria[edit]
Sicily[edit]
  • A peace agreement is reached between Syracuse and Carthage. The peace restricts Carthaginian power in Sicily to the area west of the Halycus (Platani) River. This agreement allows the tyrant of Syracuse, Agathocles, to strengthen his rule over the Greek cities of Sicily.

Greece[edit]
  • Demetrius shows ingenuity in devising new siege engines a wheeled siege tower named Helepolis (or "Taker of Cities") which stands 40 meters tall and 20 meters wide and weighs 180 tons.[7]
  • The Siege of Rhodes ends after a year.
  • Demetrius Poliorcetes and the Rhodians came to a truce, with the agreement that the city should be autonomous, should keep its own revenue and the Rhodians should be allies of Antigonus unless he is at war with Ptolemy.[8]
  • Antigonus then concludes a peace treaty and an alliance with the island state, guaranteeing it autonomy and neutrality in his conflicts with Ptolemy.[9][8]
  • Cassander invades Attica and besieges Athens. Demetrius Poliorcetes drives Cassander out of central Greece and liberates Athens. In return, the Athenians bestow on him a new religious honour, synnaos ("having the same temple") of the temple of the goddess Athena.
Roman Republic[edit]
  • The second Samnite war formally ends with a peace agreement in which the Samnites obtain peace on terms that are severe but not as crushing as those agreed by the Romans with the Etruscans four years earlier. Under the peace, Rome gains no territory, but the Samnites renounce their hegemony over Campania. Rome is also successful in ending the revolts amongst the tribes surrounding Roman territory.[10]

  • Antigonus' son Demetrius Poliorcetes attacks Cassander's forces in Thessaly. Cassander loses his possessions south of Thessaly to Demetrius. Antigonus and Demetrius crown their success by renewing the pan-Hellenic league. Ambassadors from all the Hellenic states (with the exception of Sparta, Messenia and Thessaly) meet at Corinth to elect Antigonus and Demetrius protectors of the new league.
  • As Antigonus is finding his enemies closing in on him, a truce is made and the gains by Demetrius have to be abandoned. Demetrius reaches Ephesus to support his father.
  • Pyrrhus is dethroned as King of Epirus by an uprising and joins Demetrius while in exile.
