The greatest warrior in the Achaian army. The Iliad is about the Trojan War, but it is primarily about the war as it is affected by Achilles' wrath, or anger. Achilles is the main character, and his inaction, or withdrawal from the fighting, is crucial to the plot. He is a complex warrior who sometimes ignores the cultural norms of his society because he sees through some of its fallacies — in particular, he sees many of the faults in the often narrow and contradictory heroic code. Achilles is also the greatest warrior and fighter among the Achaians. He is invulnerable (except on the heel) because his mother dipped him in the River Styx as a baby. Furthermore, no warrior comes close to being his equal as a fighter.
Achilles has a strong sense of social order that in the beginning, manifests itself in his concern for the disorder in the Achaian camp; a deadly plague is destroying the soldiers, and Achilles wants to know the reason why. His king, Agamemnon, will not act, so Achilles decides to act: He calls for an assembly of the entire army. In doing this, Achilles upsets the order of protocol; only Agamemnon can decide to call an assembly, but Achilles does so to try to return order to the Achaian camp. He succeeds, partially. He finds out why the plague is killing hundreds of Achaian soldiers, but in the process, he creates disorder when it is revealed that Agamemnon is responsible for the deadly plague. Thus, Achilles' attempt to return order to the Achaian camp does little, ultimately, to establish order. Apollo lifts the plague, but after Achilles withdraws himself and his troops from the Achaian army, disorder still remains among the Achaians.
