What was Helen of Troy the goddess of?

Helen was not a god(dess). She was a beautiful mortal woman who was the cause of a lot of trouble (though it wasn't really her fault).

Helen was abducted, and the efforts of her relatives and their friends (and their friends, etc.) to get her back resulted in the Trojan War.

Improved answer:

Helen was a godess, I am not sure what of though! I will get back to you on this.....

Improved answer:

Helen is a Demi-goddess her mother was a human and her father was a god (Zeus) she is the goddess of beauty and perfection also lust

Helen was human and then she became the goddess of consolidation.
