How did Paris commit treason to troy in the Trojan war?

Paris committed treason to Troy by abducting Helen, the wife of Menelaus, king of Sparta. This act not only violated the guest-host relationship but also ignited the Trojan War, as Menelaus sought to retrieve Helen with the help of other Greek kings. Paris's decision to take Helen, who was considered the most beautiful woman in the world, ultimately led to the downfall of Troy and was seen as a betrayal of his own city and family.
