When the Titan god Kronos was defeated by the mighty Zeus, the world was split between Zeus and his two elder brothers, Hades and Poseidon. Zeus took realm of the sky and heavens, Hades that which is under the Earth, and Poseidon was given the seas. The earth was to remain unclaimed, a realm shared by the three of them. Zeus remained the most powerful and chief god of the Greek pantheon, but Poseidon remained a powerful and important god in Greek myth, culture and society. This text offers a general introduction into the birth of Poseidon, his role in the Greek pantheon, written lore, and culture.
