Hades was the eldest son of Cronus and Rhea. Interestingly, he was also the last son to be regurgitated by his father.
Alongside his brothers Zeus and Poseidon, they defeated the previous generation of gods, the Titans, and claimed joint rulership over the cosmos.
Hades received dominion over the underworld, while Zeus ruled the sky, and Poseidon commanded the sea. The solid earth, previously under Gaia, was shared by all three.
