Origins and Birth
The Titanomachy
Poseidon was the son of the Titans Cronus and Rhea, making him a sibling to other major gods like Zeus and Hades. Similar to his brothers, Poseidon was swallowed at birth by his father Cronus, who feared a prophecy that one of his children would overthrow him. He was later saved by Zeus, who forced Cronus to regurgitate his siblings, leading to the subsequent war known as the Titanomachy. The Olympian gods, led by Zeus, eventually defeated the Titans and divided the world among themselves, with Poseidon gaining control over the sea.

Following the victory over the Titans, the three brothers—Zeus, Poseidon, and Hades—drew lots to divide their rule over the cosmos. Zeus took the sky, Hades the underworld, and Poseidon the sea. As the god of the sea, Poseidon commanded the oceans and everything within them, becoming a critical figure in maritime activities and naval warfare.
