The ancient civilization that developed a polytheistic religion with gods like Zeus and Hera is Ancient Greece. The Greeks worshipped a pantheon of deities, each having distinct roles, personalities, and domains such as love, war, agriculture, and the sea. Olympian gods were central to both public and private life, influencing culture, art, and politics. Festivals and rituals were dedicated to honoring these gods, with the Olympic Games being one of the most significant events celebrating Zeus. This rich mythology not only shaped Greek civilization but also left a profound legacy on Western literature, art, and philosophy.
