Athenian Reasons
- Loss of confidence over recent defeats at Delium and Amphipolis
- Apprehensive about allies - fear of revolts
- Regretting their rejection of peace after Pylos
Spartan Reasons
- Anxiety to get back Spartan prisoners taken during Pylos campaign
- Sparta's territory was being raided from Pylos and Cythera
- Helots likely to revolt
- Thirty Years' Peace with Argos coming to an end
Terms of the Treaty - Thucydides 5.17
- It was to last 50 years
- Delphi was to be free
- Disputes were to be settled by law and alterations to the treaty made by mutual consent
- Chalcidice was to be independent
- Amphipolis and Panactum were to be given back to Athens
- Pylos, Cythera and Methana were to be returned to Sparta
- All prisoners were to be exchanged
Thucydides' View of the Period: Shifting Alliances 5.25-6
- "The states which had accepted the treaty were at peace; but the Corinthians and some of the cities in Peloponnese trying to disturb the settlement, a fresh agitation was instantly commenced by the allies against Lacedaemon. Further, the Lacedaemonians, as time went on, became suspected by the Athenians through their not performing some of the provisions in the treaty; and though for six years and ten months they abstained from invasion of each other's territory, yet abroad an unstable armistice did not prevent either party doing the other the most effectual injury, until they were finally obliged to break the treaty made after the ten years' war and to have recourse to open hostilities"
- "Only a mistaken judgment can object to including the interval of treaty in the war. Looked at by the light of facts it cannot, it will be found, be rationally considered a state of peace, where neither party either gave or got back all that they had agreed, apart from the violations of it which occurred on both sides in the Mantinean and Epidaurian wars and other instances, and the fact that the allies in the direction of Thrace were in as open hostility as ever, while the Boeotians had only a truce renewed every ten days"
- In Thucydidies' view, though peace was signed, hostility still continued in the Greek world
Changing Alliances 421-416 BC
Discontent of Sparta's Allies
- Refusal to ratify the treaty:
- Corinth - lost possession with no compensation
- Megara - Chief harbour Nisaea still in Athenian hands
- Boeotia - refused to give back Panactum
- Sparta's reactions: Formed an alliance with Athens. The treaty was never fully implemented
- Amphipolis not returned to Athens [objections by the inhabitants]
- Pylos not returned to Sparta
- Thucydides 5.17, 5.25
New Alignment of Powers
- The resentment of the Spartan allies lead to political upheaval and alliance reshuffling i.e: joining a secret unofficial alliance with Argos
- "The Corinthians pointed out that Lacedaemon could have no good end in view, but only the subjugation of Peloponnese, or she would never have entered into treaty and alliance with the once detested Athenians, and that the duty of consulting for the safety of Peloponnese had now fallen upon Argos" - Thucydudes 5.27
- Aware of the coalition Sparta implemented plans to get her allies back - risking a break of the Athenian alliance
In Athens: Alcibiades
- After the death of Cleon at Amphipolis, Nicias held the greatest authority over the Athenians
- However, he would face a new challenge from among the demagogues, in the form of Alcibiades:
- Born into one of the famous aristocratic families of Athens, the Alcmaeonidae (shield-signallers at Marathon)
- Famed for his beauty, charm and wit - he was the student of the famous philosopher Socrates, who saved his life at the Battle of Potidaea
- Pericles acted as a guardian after his father, Cleinias, died at the Battle of Coronea (between Athens and Boeotia during the First Peloponnesian War)
Writers' Views of Alcibiades
- "You shall not rear a lion cub in the city, but if one is brought up, accommodate its ways" - Aristophanes
- "He was exceedingly ambitious of a command by which he hoped to reduce Sicily and Carthage, and personally to gain in wealth and reputation by means of his successes. The position he held among the citizens led him to indulge his tastes beyond what his real means would bear, both in keeping horses and in the rest of his expenditure; and this later on would contribute to the ruin of the Athenian state" - Thucydides
- "Although publicly his conduct of the war was as good as could be desired, individually, his habits gave offence to every one, and caused them to commit affairs to other hands, and thus before long to ruin the city" - Thucydides
- "His character displayed many inconsistencies and marked changes, as was natural amid his vast undertakings and varied fortunes. He was naturally a man of many strong passions, the mightiest of which were the love of rivalry and the love of pre-eminence." - Plutarch
Alcibiades Undermining the Peace
- Aim of Alcibiades - Discard the alliance, win over Argos risking war with Sparta
- Historical thought on Alcibiades' motivation:
- Thucydides - Alcibiades believed the Spartans could not be trusted (5.43)
- Plutarch - Alcibiades aimed to violate the treaty out of sheer jealousy of Nicias' success and fame (14-15)
Thucydides, 5.43
"The breach between the Lacedaemonians and Athenians having gone thus far, the party at Athens, also, who wished to cancel the treaty, immediately put themselves in motion. Foremost amongst these was Alcibiades, son of Clinias, a man yet young in years for any other Hellenic city, but distinguished by the splendour of his ancestry. Alcibiades thought the Argive alliance really preferable, not that personal resentment had not also a great deal to do with his opposition; he was offended with the Lacedaemonians for having negotiated the treaty through Nicias and Laches, and having overlooked him on account of his youth, and also for not having shown him the respect due to the ancient connection of his family with them as their proxeni, which, renounced by his grandfather, he had lately himself thought to renew by his attentions to their prisoners taken at Sphacteria. Being thus, as he thought, slighted on all hands, he had in the first instance spoken against the treaty, saying that the Lacedaemonians were not to be trusted, but that they only sough an alliance in order to be enabled by this means to crush Argos, and afterwards to attack Athens alone; and now, immediately upon the above occurring, he sent privately to the Argives, telling them to come as quickly as possible to Athens, accompanied by the Mantineans and Eleans, with proposals of alliance; as the moment was propitious and he himself would do all he could to help them."
Athenian/Argive Alliance
- In order to sow discord for Sparta, Alcibiades arranged an agreement between Argos, Athens, Mantinea and Elis
- What is the strategic importance of this manoeuver?
- Corinth and Megara decided to re-join the Spartan Alliance for protection purposes
Role of Agis
- After realising that the Peloponnesian allies were beginning to turn against their Spartan leaders, King Agis of Sparta decided to march against Argos with her full army as well as the Tegeans and some other allies from Arcadia
- They were joined by other Peloponnesian Allies = 11,000 Boeotians, 2,000 Corinthians; Phliasians = entire force
- With such a considerable force, it was thought the Spartan coalition would crush the Argives and reassert Spartan dominance. However, King Agis took an unusual step:
- He met with a few representatives of the Argives and concluded a four month truce without consulting the other Peloponnesian allies
- Consequence - Agis severely criticised and forced to accept a 10 man board of special advisors to prevent further political blunders
- "The Lacedaemonians and allies followed their general out of respect for the law, but amongst themselves loudly blamed Agis for going away from so fair a field (the enemy being hemmed in on every side by infantry and cavalry) without having done anything worthy of their strength" - Thucydides, 5.60
Truce Broken
- Not long after it was signed, the Argives break the truce signed with Agis and the Spartans and continue hostilities. Why?
- "The Argives blamed the persons who had concluded the truce without consulting the people, themselves thinking that they had let escape with the Lacedaemonians an opportunity such as they should never see again; as the struggle would have been under the walls of their city, and by the side of many and brave allies" (5.60)
- "Alcibiades told the Argives and the allies that they had no right to make a truce at all without the consent of their fellow confederates, and now that the Athenians had arrived so opportunely the war ought to be resumed" (5.61)
- The Argives began incursions into Laconia, forcing the Spartans and King Agis once again to march out and meet them - though this time without the support of their other allies, who had all been sent home
Battle of Mantinea 418 BC
- Spartan alliance vs Athenian/Argive Coalition met on the battlefield near Mantinea in 418 BC:
- Spartan Alliance:
- 3,500 Spartiates
- 600 Skiritae
- 2,000 Helots
- Neodamodeis
- 3,000 Tegean infantry and cavalry
- Roughly 9,000 in total
- Argive Alliance:
- 3,000 Argives
- 1,000 Athenians
- 2,000 Mantineans
- 1,000 Arcadian Mercenaries
- 1,000 other allied infantry and cavalry
- Roughly 8,000 in total
- The battle ended with a Spartan victory over Argos and Athens
- "The imputations cast upon them by the Hellenes at the time, whether of cowardice on account of the disaster at Sphacteria, or of mismanagement and slowness generally, were all wiped out by this single action: fortune, it was thought, might have humbled them, but the men themselves were the same as ever" Thucydides 5.75
- Outcome:
- Sparta and Argos concluded a 50 year alliance [begun 415 BC]
- Mantineans re-join the Spartan Alliance [stronger by 417 BC]
