The Division of the Cosmos
After the defeat of the Titans, Zeus, Poseidon and Hades divide the great realms of the cosmos between them.
The Story
With the Titans defeated, the younger gods faced a new problem: victory had given them control of the cosmos, but that power still had to be organised.
The three brothers Zeus, Poseidon and Hades divided the principal realms between them.
Zeus received the sky and became the dominant ruler among the gods. Poseidon received the sea, while Hades became ruler of the Underworld and the dead.
The earth itself and Mount Olympus were not simply assigned in the same way and remained places in which the gods could act and share interests.
This division established the broad structure of the divine world familiar from later Greek mythology.
Zeus' position was particularly important. He was not merely god of the sky and thunder. His victory over Cronus and leadership during the Titanomachy placed him at the centre of the new divine order.
Yet the Olympian world was not an absolute monarchy in which every god simply obeyed Zeus. Poseidon remained immensely powerful. Hades ruled his own realm, while older gods and divine powers retained honours and spheres of influence.
Zeus therefore governed a complicated family of powerful immortals whose interests frequently conflicted.
The age of the Titans had ended, but the stability of the new order was not yet guaranteed.

Why It Matters
The division of the cosmos establishes the political geography of later Greek mythology: Zeus in the sky, Poseidon in the sea and Hades in the Underworld. Most later divine and heroic stories take place within this Olympian order.
Traditions & Variations
Homer describes Zeus, Poseidon and Hades receiving their realms by lot. Ancient Greek religion and mythology remained more complicated than a simple three-way division, however, with many gods retaining authority across overlapping parts of the cosmos.
