In which book of the Iliad is Hector killed?

Hector is killed in Book 22 of Homer’s Iliad.

After Patroclus dies, Achilles returns to battle with a single purpose: revenge. He drives the Trojans back to Troy and pursues Hector, who remains outside the city despite his parents’ pleas. Achilles chases him around the walls three times before Athena, disguised as Hector’s brother Deiphobus, tricks Hector into stopping for a final duel.

Hector asks that the winner return the loser’s body, but Achilles refuses. Achilles then strikes Hector in the throat, the only unprotected part of his armor, and Hector dies after predicting that Paris and Apollo will eventually kill Achilles.

The story does not end with Hector’s death. Achilles ties the body to his chariot and drags it behind him, dishonoring the fallen prince. The gods preserve Hector’s corpse, and in Book 24 Achilles finally returns it to King Priam. The Iliad ends with Hector’s funeral rather than the fall of Troy.
