Step-by-step explanation:
Helen's part in the Trojan War was indeed pivotal. In Greek mythology, Helen of Troy is said to be the cause of the Trojan War. Helen was the most beautiful woman in the world and was married to Menelaus, the king of Sparta. However, she was kidnapped by Paris, the prince of Troy, which triggered the entire conflict. This caused the Greek kingdoms, under the leadership of King Agamemnon of Mycenae, to wage war against Troy. Therefore, Helen's elopement with Paris was the spark that ignited the battle.
