Why does Juno hate Aeneas?

First and foremost, Juno hates Aeneas because he is a Trojan. The Trojan War began with the Judgement of Paris. Paris, a Trojan prince determined that Venus was the best goddess of all over Pallas Athena and Juno. Venus rewarded Paris with the most beautiful woman in the world, Helen, a Greek princess. Well, Helen's husband invaded Troy to get his wife back. The gods chose sides in the war, and Juno was on the side of the Greeks. Juno also hates Aeneas because he is the hero that will defeat her kingdom. Juno loves Queen Dido and her kingdom of Carthage, but Fate foretells that Aeneas will come and create an empire that will defeat Carthage. Juno tries to keep Aeneas away from Italy, but in the end surrenders to Fate and helps Aeneas in his quest.
