How did Hades get his title?

Hades earned his title as the god of the underworld in ancient Greek mythology, derived from his role overseeing the realm of the dead. The name "Hades" itself means "the unseen," reflecting his association with the hidden aspects of the afterlife. He was one of the three main brothers, along with Zeus and Poseidon, who divided the cosmos after defeating the Titans. While Zeus took the sky and Poseidon the sea, Hades was given dominion over the underworld, solidifying his title and role in mythology.
