What is the role of the marriage pact in Trojan war?

In the context of the Trojan War, the marriage pact refers to the agreement made by the suitors of Helen, the beautiful daughter of Zeus and Leda. To win her hand, they pledged to support her chosen husband, Menelaus, should any conflict arise. This pact ultimately led to the Greek coalition against Troy when Paris, a Trojan prince, abducted Helen, prompting Menelaus and his allies to launch the war to retrieve her. Thus, the marriage pact served as a catalyst for the war, highlighting themes of honor, loyalty, and the consequences of desire.
