Zeus king of the gods

Zeus  is the king of the gods, the ruler of Mount Olympus, and god of the sky and thunder, in Greek mythology. His symbols are the thunderbolt, bull, eagle and the oak.

The son of Cronus and Rhea, he was the youngest of his siblings. He was married to Hera in most traditions, although at the oracle of Dodona his consort was Dione: according to the Iliad, he is the father of Aphrodite by Dione. Accordingly, he is known for his erotic escapades, including one pederastic relationship, with Ganymede. His trysts resulted in many famous offspring, including Athena, Apollo and Artemis, Hermes, Persephone (by Demeter), Dionysus, Perseus, Heracles, Helen, Minos, and the Muses (by Mnemosyne); by Hera he is usually said to have sired Ares, Hebe and Hephaestus.

His Roman counterpart was Jupiter, and his Etruscan counterpart was Tinia.
 

Birth
Cronus sired several children by Rhea: Hestia, Demeter, Hera, Hades, and Poseidon, but swallowed them all as soon as they were born, since he had learned from Gaia and Uranus that he was destined to be overcome by his own son as he had overthrown his own father— an oracle that Zeus was to hear and avert. But when Zeus was about to be born, Rhea sought Gaia to devise a plan to save him, so that Cronus would get his retribution for his acts against Uranus and his own children. Rhea gave birth to Zeus in Crete, handing Cronus a rock wrapped in swaddling clothes, which he promptly swallowed. His mother hid Zeus in a basket under a tree and was raised by a shepherd family under the promise that their sheep would be saved from wolves.
 

Zeus becomes king of the gods
After reaching manhood, Zeus forced Cronus to disgorge first the stone (which was set down at Pytho under the glens of Parnassus to be a sign to mortal men, the Omphalos) then his siblings in reverse order of swallowing. In some versions, Metis gave Cronus an emetic to force him to disgorge the babies, or Zeus cut Cronus' stomach open. Then Zeus released the brothers of Cronus, the Gigantes, the Hecatonchires and the Cyclopes, from their dungeon in Tartarus (The Titans; he killed their guard, Campe. As gratitude, the Cyclopes gave him thunder and the thunderbolt, or lightning, which had previously been hidden by Gaia.) Together, Zeus and his brothers and sisters, along with the Gigantes, Hecatonchires and Cyclopes overthrew Cronus and the other Titans, in the combat called the Titanomachy. The defeated Titans were then cast into a shadowy underworld region known as Tartarus. Atlas, one of the titans that fought against Zeus, was punished by having to hold up the sky.

After the battle with the Titans, Zeus shared the world with his elder brothers, Poseidon and Hades, by drawing lots: Zeus got the sky and air, Poseidon the waters, and Hades the world of the dead (the underworld). The ancient Earth, Gaia, could not be claimed; she was left to all three, each according to their capabilities, which explains why Poseidon was the "earth-shaker" (the god of earthquakes) and Hades claimed the humans that died. (See also: Penthus)

Gaia resented the way Zeus had treated the Titans, because they were her children. Soon after taking the throne as king of the gods, Zeus had to fight some of Gaia's other children, the monsters Typhon and Echidna. He vanquished Typhon and trapped him under a mountain, but left Echidna and her children alive.


Zeus and Hera
Zeus was brother and consort of Hera. By Hera, Zeus sired Ares, Hebe and Hephaestus, though some accounts say that Hera produced these offspring alone. Some also include Eileithyia as their daughter. The conquests of Zeus among nymphs and the mythic mortal progenitors of Hellenic dynasties are famous. Olympian mythography even credits him with unions with Leto, Demeter, Latona, Dione and Maia.

Among the mortals: Semele, Io, Europa and Leda. (For more details, see below).

Many myths renders Hera as jealous of his amorous conquests and a consistent enemy of Zeus' mistresses and their children by him. For a time, a nymph named Echo had the job of distracting Hera from his affairs by incessantly talking: when Hera discovered the deception, she cursed Echo to repeat the words of others.
