Short answer: the Greek divine family tree has four generations. First the primordials (Chaos, Gaia, Nyx, Eros). Then the Titans, children of Gaia and Uranus. Then the Olympians, children of the Titans Cronus and Rhea. And finally the younger gods, mostly children of Zeus. Learn one parent pair per generation and the whole tree unfolds.
Generation by generation
| Generation | Who | Born from |
|---|---|---|
| 1. Primordials | Chaos, Gaia, Tartarus, Eros, Nyx, Erebus | Emerged from Chaos |
| 2. Titans | Cronus, Rhea, Oceanus, Atlas, Prometheus, Leto... | Gaia + Uranus |
| 3. Elder Olympians | Zeus, Hera, Poseidon, Hades, Demeter, Hestia | Cronus + Rhea |
| 4. Younger Olympians | Athena, Apollo, Artemis, Hermes, Ares, Dionysus | Mostly Zeus + various mothers |
The three unusual births worth memorizing
Exams love the exceptions. Athena was born in full armor from the head of Zeus. Aphrodite, in Hesiod's version, rose from the sea foam and is older than Zeus himself. And Dionysus was born twice, sewn into the thigh of Zeus after his mother Semele burned. If a question looks like a trick, it is probably one of these three.
Where the heroes hang from the tree
The great heroes are the tree's lowest branches: Heracles and Perseus are sons of Zeus by mortal women, and Achilles is the son of the sea nymph Thetis. That is the pattern to remember: heroes are the children of one god and one mortal, carrying the family gift and the family curse at once.
Quick questions
Who came first, the Titans or the Olympians?
The Titans. They are the second generation (children of Earth and Sky) and ruled before the Olympians, their own children, overthrew them.
Are all the Olympians children of Zeus?
No. Six are his siblings (Hera, Poseidon, Hades, Demeter, Hestia and Zeus himself), children of Cronus and Rhea. The younger set are mostly his children. The full list, with domains and symbols, is in our table of the 12 Olympians.
What is the fastest way to memorize the tree?
Four names, one per generation: Chaos, Uranus, Cronus, Zeus. Each one is the father or origin of the next. Every other god hangs off one of those four hooks.
Every name in this tree has a full illustrated profile in our encyclopedia of gods, and the whole dynasty is narrated as a series in MythologyNow.
