By Place

Greece

* In the wake of the Macedonian victory at Olynthus, Athens seeks to make peace with Macedonia. Because his financial policy is based on the assumption that Athens should not be involved in major wars, the Athenian leader, Eubulus, works for peace with Philip II of Macedon. Demosthenes is among those who support a compromise.
* An Athenian delegation, comprising Demosthenes, Aeschines and Philocrates, is officially sent to Pella to negotiate a peace treaty with Philip II. During the negotiations, Aeschines seeks to reconcile the Athenians to Macedonia's expansion into Greece.

Roman Republic

* Coinage is introduced into Rome for the first time.
