Why do Achilles and agamemnon dislike each other?

Achilles and Agamemnon dislike each other primarily due to a clash of pride and authority. Agamemnon, the leader of the Greek forces, dishonors Achilles by taking his war prize, Briseis, which undermines Achilles' status and honor as a warrior. This conflict escalates into a personal feud, highlighting themes of pride, respect, and the consequences of personal grievances within the broader context of the Trojan War. Their animosity ultimately affects the Greek campaign against Troy.
