Hera was the wife of Zeus while Apollo was his son from Leto. Poseidon was named the lord of the seas and received the rivers and the oceans, Hades received the underworld where he ruled over the souls of the deceased, while Zeus received the heavens and became the king of the Greek Gods. Poseidon and his brothers then shared the world by drawing lots. In this battle, the Olympians, the younger generation led by Zeus defeated the Titans and overthrew Cronus.

Along with his siblings, the Hecatonchires and the Cyclopes Poseidon fought against Cronus and the other Titans in the Battle of the Gods known as Titanomachy. Depiction of Cronus disgorging his childrenДЄfter Poseidon was rescued from Cronus by Zeus, he teamed up with him and his other siblings against Cronus and the Titans. There is another version of this myth which suggests that Rhea had already saved Poseidon by hiding him among a flock of lambs and instead telling Cronus that she had given birth to a colt. This led to Cronus disgorging ZeusвЂ™ siblings: his sisters Hestia, Demeter and Hera and his brothers Hades and Poseidon. When Zeus came of age, he disguised himself as an Olympian cup-bearer poisoned his fatherвЂ™s wine with a potion and tricked him to drink it. However, when her sixth child Zeus was born, Rhea hid him in a cave and instead gave Cronus a stone wrapped in his clothes which he swallowed. Cronus had several children with Rhea but swallowed them all at birth. However he was told that one of his children would go on to overthrow him like he had overthrown his father. According to Greek mythology, Cronus overthrew his father Uranus and ruled over the world along with his wife Rhea.
