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


  • Athenian general Cimon sails to Cyprus with two hundred triremes of the Delian League. From there, he sends sixty ships to Egypt to help the Egyptians under Amyrtaeus, who is fighting the Persians in the Nile Delta. Cimon uses the remaining ships to aid an uprising of the Cypriot Greek city-states against Persian control of the island. Cimon lays siege to the Persians stronghold of Citium on the south west coast of Cyprus. However, the siege fails and Cyprus remains under Phoenician (and Persian) control.
  • During the siege Cimon dies and the command of the fleet is given to Anaxicrates, who leaves Citium to engage the Phoenician fleet in the Battle of Salamis in Cyprus. The Greek fleet is victorious against the Persians and their allies and then returns to Athens.
  • The Athenians reduce the tribute due from their subject city-states (ie members of the Delian League), and each city is allowed to issue its own coinage.
  • 5,000 talents are transferred to the treasury of the Delian League in Athens.
  • The Temple of Theseus is completed in Athens.


Roman Republic[edit]

  • The success of the first Decemvirate prompts the appointment of a second Decemvirate which also includes plebeians amongst its members. This second decemviri adds two more headings to their predecessor's ten, completing the Law of the Twelve Tables (Lex Duodecim Tabularum), which will form the centrepiece of Roman law for the next several centuries. Nevertheless, this Decemvirate's rule becomes increasingly violent and tyrannical.


  • After minor preliminary successes (including the capture of Inessa from its Greek colonists), Ducetius, a Hellenised leader of the Siculi, an ancient people of Sicily, is decisively defeated by the combined forces of Syracuse and Acragas. Ducetius flees to exile in Corinth.
