Editing 450 BC (section)

=== By place ===

==== Greece ====
* [[Athenian]] [[general]] [[Cimon]] sails to [[Cyprus]] with two hundred [[trireme]]s of the [[Delian League]]. From there, he sends sixty ships to [[Egypt]] to help the Egyptians under [[Amyrtaeus]], who are fighting the [[Achaemenid Empire|Persians]] in the [[Nile Delta]]. Cimon uses the remaining ships to aid an uprising of the [[Greek Cypriots|Cypriot Greek]] city-states against [[Achaemenid Empire|Persian]] control of the island. He lays siege to the [[Achaemenid Empire|Persian]] stronghold of [[Citium]] on the southern west coast of Cyprus. However, the siege fails and Cyprus remains under [[Phoenicia]]n (and Persian) control.
* During the siege Cimon dies and command of the fleet is given to Anaxicrates, who leaves Citium to engage the Phoenician fleet in the [[Battle of Salamis in Cyprus (450 BC)|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 (i.e. members of the Delian League), and each city is allowed to issue its own coinage.
* 5,000 [[Talent (measurement)|talents]] are transferred to the treasury of the Delian League in Athens.

==== Macedonia ====
* [[Perdiccas II of Macedon|Perdiccas II]] succeeds [[Alexander I of Macedon|Alexander I]] as king of [[Macedon]]ia (approximate date).

==== Roman Republic ====
* 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.

==== Sicily ====
* 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, Sicily|Syracuse]] and [[Agrigento|Acragas]]. Ducetius flees to exile in [[Corinth]].
