Argos

Argos was a city-state in ancient Greece, largely eclipsed by Sparta in prominence and importance.

Argos played a role in the mythology of the Trojan War at which time it was said to be ruled by Diomedes. "Argos" could also refer to the entire Argolid, which was the kingdom of Agamemnon. As Agamemnon was the commander of the entire Greek force, "Argos" also could refer very generally to all of allied Greece during the Trojan War. The kingdom of Achilles was sometimes referred to as "Pelasgian Argos".
