Ares (Ancient Greek: Ἄρης /árɛːs/, Μodern Greek: Άρης /ˈaris/) is the god of war. He is a member of the Twelve Olympians, a son of Zeus and Hera, in Greek mythology. Though often referred to as the Olympian god of warfare, he is more accurately the god of bloodthirst, or slaughter personified: "Ares is apparently an ancient abstract noun meaning throng of battle, war." He also presides over the weapons of war, the defense and sacking of cities, rebellion and civil order, banditry, manliness and courage. In Greek mythology it is believed that the cause of every conflict is the fault of Ares, the god of war.
