Year 405 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Barbatus, Capitolinus, Cincinnatus, Medullinus, Iullus and Mamercinus (or, less frequently, year 349 Ab urbe condita). The denomination 405 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.

Events

By place

Greece

After their victory in the Battle of Arginusae over the Spartans, the Athenian fleet follows the reappointed Spartan admiral, Lysander, to the Hellespont. The Athenian fleet under Admiral Conon is destroyed by the Spartans under Lysander in the Battle of Aegospotami in the Sea of Marmara and Conon flees to Cyprus.
The Spartan king Pausanias lays siege to Athens while Lysander's fleet blockades Piraeus. This action closes the grain route through the Hellespont, thereby starving Athens.
While the Peloponnesians besiege Athens, Theramenes tries to negotiate with Lysander. He is away for three months while Athens is being reduced to starvation. Then he heads the embassy that negotiates the terms of capitulation to the Spartans.

Sicily

Dionysius the Elder rises to power as the tyrant of Syracuse. He makes peace with the Carthaginian general, Hamilco (whose army has been weakened by the plague), and fortifies Syracuse. This treaty leaves Carthage in control of most of Sicily.
Dionysius the Elder ruthlessly consolidates and expands his power. He builds a wall around Syracuse and fortifies Epipolae. The Greek citizens of Naxos, Catana, and Leontini are removed from their cities; many of them are enslaved and their homes are given to Sicilian and Italian mercenaries. Dionysius prepares his army to fight against Carthage, which now occupies western and southern Sicily.
