First Generation Deities

The First Generation Deities in Greek Myth are known as the Titans!

These were the children of the Earth (Gaea/Gaia) and Sky (Uranus/Ouranos).

The Titans:

Cronus, Rhea, Iapetus, Oceanus, Hyperion, Themis, Thea, Mnemosyne, Phoebe, Coeus, Tethys, and Cruis.

The Titans paired up in various ways with siblings to produce future generations.

Decidedly 'humanoid' Titans, Cronus and Rhea paired up to give us the Olympians.

Iapetus is the father of Prometheus, and also of Atlas and Epimetheus.

Oceanus is the father of nymphs

Hyperion is considered the Sun-God, and father of moon and dawn.
Thea is Hyperion's mate.

Themis became Zeus' second consort and together, they created the Hours and the Fates.

The Muses were created by Mnemosyne and Zeus (he really got around with the women)

Phoebe and Coeus paired together, and are considered the parents of Leto and Asteria (Leto, who would mate later with - guess who? You got it - Zeus)

Oceanus and Tethys paired together

And Crius is considered father of Pallas, Astraeus, and Perses


Now these aren't the only offspring from Uranus and Gaea - these are just the ones called The Titans.

Uranus and Gaea also had other offspring that weren't necessarily 'human'-looking.
Some of these were

The Hecatoncheires or 100-Handers - and also - the Cyclopes. The non-human looking offspring were confined to the Underworld in the place known as Tartaros.

It was Uranus' decision to lock certain offspring up, and Gaea was very displeased about having her offspring confined that way so she appealed to her other children, The Titans, for help. None of them were interested in helping their mother or their different-looking 'siblings', save for Cronus. Cronus agree to act on behalf of Gaea and help liberate some of the other offspring if possible.

The only way to help the offspring stuck down in Tartaros was to usurp (un-wedge from power) Uranus. Gaea gave her son, Cronos a sickle and with this, he castrated his father, Uranus - who was then unfit to hold seat as Ruler.

The position then was given to Cronos who freed the 100-Handers and the Cyclopes.

The freedom didn't last long. Perhaps Cronos quickly began to feel the power within the 100-Handers and the Cyclopian offspring. Whatever the case, they didn't enjoy freedom for long. Cronos imprisoned them again to the Underworld just as his father had done.

From there, Cronos paired with Rhea and together they made The Olympian Gods and Goddesses.
