What daughter of Zeus was the cause of the Trojan war?

The daughter of Zeus and Hera was Eris, the goddess of discord. She wasn't invited to a wedding so she brought a golden Apple and said it was for the fairest goddess. Hera, Aphrodite, and Athena argued over it and asked Paris to make the decision. Paris chose Aphrodite because she promised he could marry the most beautiful girl in the world. He chose Helen but her husband didn't like the idea and the war started.
