Who was Alcibiades?
Alcibiades was born in Athens around 450 BC. His mother was an Alcmaeonid. He was from one of the richest families in Athens, and he grew up with the best of everything. After his father was killed in battle, Pericles, another Alcmaeonid, was Alcibiades' guardian. When he was a teenager, during the early years of the Peloponnesian War, Socrates was Alcibiades' teacher.
But when Alcibiades got in trouble with the Athenians over the question of who smashed the good-luck statues, he ended up running away from Athens to Sparta in the middle of the night.
When Alcibiades got to Sparta, he made a deal with the Spartans. If they would let him stay in Sparta, he would help them win the Peloponnesian War by giving them good advice. They agreed, and the first thing Alcibiades told the Spartans was that they should build a navy and use it to destroy the Sicilian Expedition.
When this plan worked, the Spartans thought Alcibiades was really smart. Alcibiades also advised them to lay a permanent siege to Athens, instead of only in the summertime. That worked too. But after a while, Alcibiades got into trouble in Sparta, too. People said he had been kissing the wife of one of the Spartan kings. He had to leave Sparta quickly.
This time Alcibiades fled to Persia. The Persian satrap (ruler) of Anatolia (modern Turkey) let him stay there, and now Alcibiades gave the Persians good advice about how to manage the Peloponnesian War.
Near the end of the Peloponnesian War, the Athenians were so desperate that they let Alcibiades come back as their general. But in the end, they fired him again, and he went back to Persia, where he was killed in 404 BC, just as the war was ending.
