Hyborian kingdom situated southwest of Ophir, west of Koth and Shem, and south of Zingara. Argos was a nation of paramount seafarers, with cosmopolitan cities along the coast. Its capital, Messantia, lay on the coast at the estuary of the Khorotas River.
The Argossean people were an amalgam of Zingaran and Shemite races. They were the best sailors in the Hyborian world - according to everyone but the mariners of Zingara!
Argos was anciently a part of Acheron. It may have been the third of the Hyborian kingdoms to be established, after Nemedia and Aquilonia. Argos had a long-standing feud with Zingara, based on their maritime rivalry. Zingara essayed an incursion into Argos when Conan was a young man. The Argosseans under King Milo trounced King Ferdrugo's invaders soundly.
