King of the gods is Zeus or his Roman equivalent, Jupiter who rules over Mount Olympus and is the god of thunder and lightning, as well as law and order. The most well-known account of how Zeus became the king of the gods comes from the Theogony by Hesiod, written around 720 BCE.

Zeus, or his Roman equivalent Jupiter, holds the esteemed title of "King of the Gods" in Greek mythology, presiding over Mount Olympus. This powerful deity is associated with thunder, lightning, law, and order, embodying a commanding presence in the divine hierarchy. The primary narrative detailing Zeus's ascension to this prominent role is chronicled in Hesiod's "Theogony," a significant work of ancient Greek literature believed to have been written around 720 BCE.

In the Theogony, Zeus emerges as a key figure in the divine succession, overcoming various challenges and conflicts to establish his supremacy. One of the pivotal moments occurs when Zeus, with his siblings, successfully overthrows his father, Cronus, and the Titans, who had ruled the cosmos. This dramatic event, known as the Titanomachy, marks the ascent of Zeus to the throne of the gods.

As the ruler of Mount Olympus, Zeus assumes a central role in the pantheon, wielding his thunderbolt and maintaining cosmic order. His reign symbolizes not only the victory of a new generation of gods but also the establishment of a more just and balanced rule. The narrative of Zeus's kingship underscores themes of power, succession, and divine authority, contributing significantly to the rich tapestry of Greek mythology.
