Zeus was both Hera's husband and also her brother. Due to Zeus' trickery and infidelity, the marriage between Zeus and Hera was often turbulent and chaotic.
Hera was worshipped in ancient Greece as the queen of heaven and the goddess of childbirth, women and family. Zeus had many other lovers besides Hera, both human and immortal. For this reason, she is often depicted as an angry and jealous wife in many Greek myths. As a result of Zeus' unfaithfulness to her in their marriage, Hera is often portrayed interfering in the lives of the human women who were the objects of Zeus' affection.
