Astyanax

In Greek mythology, Astyanax ("king of the city") was the son of Hector and Andromache. He was killed during the Trojan War by Neoptolemus, who threw the infant from a wall and told his mother "Since my father (Achilles) killed his father (Hector) he might try to avenge the death. He also could become King of Troy, and we want no more kings of Troy!" (Iliad VI, 403, 466; Aeneid II, 457)
