Ares is a Greek God, son of the king and queen of the gods, Zeus and Hera in the ancient Greek religion. The cult of Ares was not very large, being centered in the northern region of Greece and in Sparta, one of the most important city-states in Ancient Greece. Although often referred to as the Olympic god of war, he is more exactly the god of wild war, bloodlust, or personified killing. The Romans identified him as Mars, the Roman god of war and agriculture.
Among the Hellenics there was always mistrust of Ares and he was detested by Zeus. Ares was generally belittled in the name of his half-sister, Athena, who although she was a goddess of war, Athena's position was one of strategic war, while Ares tended to be the unpredictable violence of war.
