Year 304 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Sophus and Saverrio (or, less frequently, year 450 Ab urbe condita). The denomination 304 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.


By place[edit]


  • Demetrius shows ingenuity in devising a new siege engine: a wheeled siege tower named Helepolis (or "Taker of Cities"), which stands 40 meters tall and 20 meters wide and weighs 180 tons.[1]
  • The Siege of Rhodes ends after a year.
  • Demetrius Poliorcetes and the Rhodians come to a truce, with the agreement that the city should be autonomous, should keep its own revenue and that the Rhodians should be allies of Antigonus unless he is at war with Ptolemy.[2]
  • Antigonus then concludes a peace treaty and an alliance with the island state, guaranteeing it autonomy and neutrality in his conflicts with Ptolemy.[3][2]
  • Cassander invades Attica and besieges Athens. He captures the island of Salamis off the coast of Athens.
  • Demetrius Poliorcetes invades mainland Greece for Asia-Minor, drives Cassander out of central Greece and liberates Athens. In return, the Athenians bestow on him a new religious honour, synnaos (meaning "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.[4]
