Pantheon
Pantheon, from the Greek for "all the gods," names the full population of Greek divinity across every generation that ever held power, not one fixed list drawn from whichever generation currently rules.

In Practice
Hesiod's Theogony lays out the structure in three distinct tiers. First come the primordial powers: Chaos, then wide-bosomed Earth, then Eros, with Erebus and Night born from Chaos in turn. Earth then bears Heaven as her own equal, and by lying with him produces the Titan generation, twelve of them named directly, Oceanus, Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys, and Cronus, youngest and most cunning of the twelve. The third tier arrives only after a war. Once the Olympians defeat the Titans in the Titanomachy, Hesiod says they "pressed far-seeing Olympian Zeus to reign and to rule over them," and Zeus "divided their dignities amongst them" rather than replacing the cosmos outright. That phrasing matters: Gaia, several Titans, and other pre-Olympian powers persist in later myth even after losing supremacy, which is why the pantheon as a whole spans three generations of real, still-active divinity rather than shrinking to whichever twelve names currently hold Olympus. Cronus himself, the youngest Titan and the one who seized power from Heaven in the generation before Zeus, is the clearest case of a demoted-but-undestroyed god: he loses his own rule in the Titanomachy yet keeps a name and a story, rather than vanishing from the pantheon the moment a new generation takes the throne. The English word's own history has a genuinely ancient precedent behind it, and not the one most readers expect. Long after the classical period this corpus mostly covers, Pausanias records the emperor Hadrian building in Athens "a temple of Hera and Zeus Panellenios (Common to all Greeks), a sanctuary common to all the gods," alongside a hundred pillars of Phrygian marble. A shrine literally dedicated to all the gods together, in other words, existed in Athens itself under Roman rule, centuries after Hesiod's three-tier cosmology first gave the concept its shape, and independently of the far more famous building in Rome that carries the same name today.
Does "pantheon" mean the same thing as "the twelve Olympians"?
No. The twelve Olympians are the current ruling generation, but the pantheon as a whole spans three tiers Hesiod's Theogony lays out in sequence: the primordial powers (Chaos, Earth, Eros, and others), the Titan generation born from Earth and Heaven, and only then the Olympians who took power after defeating the Titans.

What are the three generational tiers of the Greek pantheon?
Primordial powers first: Chaos, then Earth, then Eros, with Erebus and Night following from Chaos. Earth then bears Heaven and, lying with him, produces the twelve Titans, including Oceanus, Rhea, Themis, and Cronus. Only after the Olympians defeat the Titans in the Titanomachy does the third tier, Zeus's own generation, take power.
Hesiod, Theogony 116-138
Did the Olympians wipe out the earlier generations of gods when they took power?
No. Hesiod says the victorious gods pressed Zeus to "reign and to rule over them" and that he "divided their dignities amongst them," language of redistributing authority rather than eliminating anyone. Gaia and several Titans, Oceanus, Tethys, Themis, Rhea, and Mnemosyne among them, remain active figures in myths set after the Titanomachy.
Hesiod, Theogony 881-885
Is there a real ancient building called a pantheon, besides the one in Rome?
Yes. Pausanias records that the emperor Hadrian built "a sanctuary common to all the gods" in Athens itself, alongside a temple honoring Zeus as "Panellenios," common to all Greeks. It stood independently of Rome's far better-known Pantheon and centuries after the Archaic and Classical texts that describe the pantheon's three-tier cosmology.

Why does Greek myth still give the older, defeated gods speaking roles after the Olympians take over?
Because losing the Titanomachy cost the Titans and earlier powers their rule, not their existence. Hesiod's own account has Zeus redistribute authority among the victors rather than erase the earlier generation, which is exactly why figures like Gaia, Themis, and Mnemosyne continue to act in myths the corpus tells about events long after the Olympians took charge.

Where Accounts Differ
- redistributing power vs replacing the earlier gods
- This entry deliberately does not restate olympian.json's coverage of the twelve Olympians debate (Hades' exclusion, the Hestia/Dionysus seat dispute, Aphrodite's two origins) -- it covers the pantheon as the full three-generation system that produces the Olympians, not the membership question olympian.json already answers in depth.
