In the Iliad, Hector was the leader of the Trojan forces, and the very model of nobility and honor. In the war against the Greeks he killed several great warriors before being slain by Achilles. His name began to take on its current meaning only after it was adopted by a crowd of bullying young rowdies in late-17th-century London.
