Why did Eris throw a golden apple labeled for the fairest into the wedding crowd?

Eris, the goddess of discord, threw a golden Apple labeled "For the Fairest" into the wedding of Peleus and Thetis to instigate conflict among the goddesses. This act led to a competition between Hera, Athena, and Aphrodite, each claiming the Apple for herself. The dispute ultimately resulted in the Judgment of Paris, which set off a chain of events culminating in the Trojan War. Eris's action epitomized her role as a bringer of chaos and strife among both mortals and deities.
