In Greek mythology, the primordial deities are the first gods and goddesses born from primordial Chaos or from Chronos and Ananke (depending on the source). Hesiod's first are Chaos,  Gaia, Tartarus, Eros and Nyx. The primordial deities Gaia and Uranus give birth to the Titans. The Titan god Cronus and Rhea give birth to Zeus, Poseidon, Hades, Hestia, Hera and Demeter who overthrow the Titans. The warring of the gods ends with the reign of Zeus.
