Who was the Trojan prince who married Helen after Paris's death?

Deiphobus was the Trojan prince who married Helen after Paris's death.

Deiphobus was a son of King Priam and Queen Hecuba, and one of Troy's leading princes. After Paris died, Helen was awarded to Deiphobus rather than his brother Helenus. The marriage belongs mainly to later Trojan War traditions, since the Iliad ends before the fall of Troy and does not narrate the entire episode in detail.

The story varies between authors. Some accounts present the marriage as a political or ceremonial arrangement, while Euripides' Trojan Women depicts Helen as having been forced into it and feeling enslaved. During the sack of Troy, Deiphobus is killed and horribly mutilated; accounts differ over whether Menelaus, Odysseus, or Helen played a direct role in his death.

Helenus is the most important alternative name to remember: he also sought Helen's hand and lost the contest to Deiphobus. In later tradition, Helenus survives Troy, becomes a prophet, and marries Andromache, Hector's widow.
