Polites was born to Priam, King of Troy, and Hecuba, his wife. He lived in Troy during his youth, was crowned prince of Troy, and was styled his royal Majesty. During his youth, Polites witnessed the Trojan War and was a supporting character in the Iliad.
During the passage of the Trojan Horse in the Trojan War, Polites was one of those who accepted the gift. During the fall of Troy and the attempted escape to Latium, Neoptolemus shot an arrow in Polites' leg. Polites fell, escaping Neoptolemus, who pursued Polites to his father's palace. Priam called on the gods to punish Neoptolemus, but in that scene, Priam was also killed by Neoptolemus.
