Zeus, the king of the gods in Greek Mythology, had many wives and mistresses, but his main wife and queen was Hera. She was the goddess of marriage and birth and was known for her jealousy and vengeful nature towards Zeus' many affairs. Despite this, Hera was a loyal wife to Zeus and the mother of many of his children, including Ares, Hebe, and Hephaestus. Their relationship was tumultuous and often reflected the power struggles that existed between men and women during that time. Hera's strength and determination made her a formidable opponent to Zeus and her presence in Greek Mythology continues to be important in modern times.
