Who was Hera, the goddess of marriage and queen of all gods?
Hera, or Here, was the wife and older sister of Zeus in Greek Mythology. She was the goddess of women and marriage. The Roman equivalant was Juno. Hera was sired by Rhea (the mother or all Gods) and Cronus (the leader of the first generation of Titans).
Hera was known to be vengeful and full of jealousy, mostly against Zeus’s offspring, although she would often focus her rage against mortals such as Palias or Paris. Paris offended Hera by deciding that Aphrodite was more beautiful than all other goddesses, Hera was not amused.
