Epigoni

In Greek mythology, the Epigoni or Epigonoi are the sons of the Argive heroes, the Seven against Thebes, who had fought and been killed in the first Theban war, the subject of the Thebaid, in which Polynices and his allies attacked Thebes because Polynices' brother, Eteocles, refused to give up the throne as promised. The second Theban war, also called the war of the Epigoni, occurred ten years later, when the Epigoni, wishing to avenge the death of their fathers, attacked Thebes.
