Rise to prominence Alcibiades first rose to prominence when he began advocating aggressive Athenian action after the signing of the
Peace of Nicias. That treaty, an uneasy truce between Sparta and Athens signed midway through the Peloponnesian War, came at the end of seven years of fighting during which neither side had gained a decisive advantage. Historians Arnold W. Gomme and
Raphael Sealey believe, and
Thucydides reports, that Alcibiades was offended that the Spartans had negotiated that treaty through Nicias and
Laches, overlooking him on account of his youth. Disputes over the interpretation of the treaty led the Spartans to dispatch ambassadors to Athens with full powers to arrange all unsettled matters. The Athenians initially received these ambassadors well, but Alcibiades met with them in secret before they were to speak to the
ecclesia (the Athenian Assembly) and told them that the Assembly was haughty and had great ambitions. He urged them to renounce their diplomatic authority to represent Sparta, and instead allow him to assist them through his influence in Athenian politics. The representatives agreed and, impressed with Alcibiades, they alienated themselves from Nicias, who genuinely wanted to reach an agreement with the Spartans. This alliance, however, would ultimately be defeated at the
Battle of Mantinea. Somewhere in the years 416–415 BC, a complex struggle took place between
Hyperbolos on one side and Nicias and Alcibiades on the other. Hyperbolos tried to bring about the
ostracism of one of this pair, but Nicias and Alcibiades combined their influence to induce the people to expel Hyperbolos instead. This incident reveals that Nicias and Alcibiades each commanded a personal following, whose votes were determined by the wishes of the leaders. An oration urging Alcibiades's ostracism, "Against Alcibiades" (historically attributed to the orator
Andocides but not in fact by him), alleges that Alcibiades had a child by one of these enslaved women.
Sicilian Expedition . Vandalizing hermai was one of the crimes of which Alcibiades was accused. In contrast, Alcibiades argued that a campaign in this new theatre would bring riches to the city and expand the empire, just as the
Persian Wars had. In his speech Alcibiades predicted (over-optimistically, in the opinion of most historians) that the Athenians would be able to recruit allies in the region and impose their rule on
Syracuse, the most powerful city of
Sicily. In spite of Alcibiades's enthusiastic advocacy for the plan, it was Nicias, not he, who turned a modest undertaking into a massive campaign and made the conquest of Sicily seem possible and safe. It was at his suggestion that the size of the fleet was significantly increased from 60 ships to "140 galleys, 5,100 men at arms, and about 1300 archers, slingers, and light armed men". Philosopher
Leo Strauss underscores that the Sicilian expedition surpassed everything undertaken by Pericles. Almost certainly Nicias's intention was to shock the assembly with his high estimate of the forces required, but, instead of dissuading his fellow citizens, his analysis made them all the more eager. Against his wishes Nicias was appointed general along with Alcibiades and
Lamachus, all three of whom were given full powers to do whatever was in the best interests of Athens while in Sicily. One night during preparations for the expedition, the
hermai, heads of the god
Hermes on a
plinth with a
phallus, were mutilated throughout Athens. This was a religious scandal, resulted in a charge of
asebeia (impiety) against Alcibiades, and was seen as a bad omen for the mission. Plutarch explains that Androcles, a political leader, used false witnesses who accused Alcibiades and his friends of mutilating the statues, and of profaning the
Eleusinian Mysteries. Later his opponents, chief among them being Androcles and Thessalus,
Cimon's son, enlisted orators to argue that Alcibiades should set sail as planned and stand trial on his return from the campaign. Alcibiades was suspicious of their intentions, and asked to be allowed to stand trial immediately, under penalty of death, in order to clear his name. This request was denied, and the fleet set sail soon after, with the charges unresolved. As Alcibiades had suspected, his absence emboldened his enemies, and they began to accuse him of other sacrilegious actions and comments and even alleged that these actions were connected with a plot against the democracy. According to
Thucydides, the Athenians were always in fear and took everything suspiciously. When the fleet arrived in
Catania, it found the state
trireme Salaminia waiting to bring Alcibiades and the others indicted for mutilating the hermai or profaning the Eleusinian Mysteries back to Athens to stand trial. Meanwhile, the Athenian force in Sicily, after a few early victories, moved against
Messina, where the generals expected their secret allies within the city to betray it to them. Alcibiades, however, foreseeing that he would be outlawed, gave information to the friends of the Syracusans in Messina, who succeeded in preventing the admission of the Athenians. With the death of Lamachus in battle some time later, command of the Sicilian Expedition fell into the hands of Nicias, admired by Thucydides (however a modern scholar has judged him to be an inadequate military leader The Spartans granted this request and received him among them. Because of this defection, the Athenians condemned him to death
in absentia and confiscated his property. In the debate at Sparta over whether to send a force to relieve Syracuse, Alcibiades spoke and instilled fear of Athenian ambition into the Spartan
ephors by informing them that the Athenians hoped to conquer Sicily, Italy, and even
Carthage. Historian
Donald Kagan believes that Alcibiades knowingly exaggerated the plans of the Athenians to convince the Spartans of the benefit they stood to gain from his help. Kagan asserts that Alcibiades had not yet acquired his "legendary" reputation, and the Spartans saw him as "a defeated and hunted man" whose policies "produced strategic failures" and brought "no decisive result". If accurate, this assessment underscores one of Alcibiades's greatest talents, his highly persuasive oratory. After making the threat seem imminent, Alcibiades advised the Spartans to send troops and most importantly, a Spartan commander to discipline and aid the Syracusans. By doing this, the Spartans cut the Athenians off entirely from their homes and crops and the silver mines of
Sunium. In spite of these valuable contributions to the Spartan cause, around this time Alcibiades fell out of favor with the government of King
Agis II.
Leotychides, the son born by Agis's wife
Timaea, Queen of Sparta (or Queen Timonassa), shortly after this, was believed by many to be Alcibiades's son. An alternate account asserts that Alcibiades took advantage of King Agis's absence with the Spartan army in
Attica and seduced his wife. It is alleged that
Astyochus, a Spartan admiral, was sent orders to kill him, but Alcibiades received warning of this order and defected to the Persian
satrap Tissaphernes, who had been supporting the Peloponnesian forces financially in 412 BC.
Defection to Achaemenid Empire in Asia Minor , who received Alcibiades as an advisor. Astyra,
Mysia. Circa 400–395 BC On his arrival in the local Persian court, Alcibiades won the trust of the powerful
satrap and made several policy suggestions which were well received. According to
Thucydides, Alcibiades immediately began to do all he could with Tissaphernes to injure the Peloponnesian cause. At his urging, the satrap reduced the payments he was making to the Peloponnesian fleet and began delivering them irregularly. Although Alcibiades's advice benefited the Persians, it was merely a means to an end; Thucydides tells us that his real motive was to use his alleged influence with the Persians to effect his restoration to Athens. Alcibiades was one of several Greek aristocrats who took refuge in the
Achaemenid Empire following reversals at home, other famous ones being
Themistocles,
Demaratos or
Gongylos. According to
Thucydides (Thuc.8.47), Alcibiades also advised the Achaemenid king (
Darius II), and therefore he may have traveled to
Susa or
Babylonia to encounter him. ==Recall to Athens==
