366 BCE
Athens founds the town of Kos on the island of Kos in the Aegean Sea. The Abduction of Persephone, detail of a wall painting in Tomb I (Small Tomb) in Vergina, Macedonia, is made (approximate date). Theban leader, Epaminondas, returns to the Peloponnesus for a third time, seeking to secure the allegiance of the states of Achaea. Although no army dares to challenge him in the field, the democratic governments he establishes there are short-lived, as pro-Spartan aristocrats soon return to the cities, reestablish the oligarchies, and bind their cities ever more closely to Sparta.
Geopolitics & Diplomacy
- The use of military tribunes with consular power is abandoned permanently and the dual consulship is restored. A new magistracy is established, which is called the praetorship. Its holder, the praetor, is elected annually by the Assembly and takes charge of civil matters, thus relieving the consuls of this responsibility. The praetor is regarded as a junior colleague of the consuls. Nevertheless, the praetor can command an army, convene a Senate or an assembly, as well as exercise the consular functions.source
