Delphic Oracle becomes pan-Hellenic arbiter
The Oracle at Delphi — the Pythia, a priestess of Apollo speaking in hexameter riddles from a trance state — emerged around the 8th century BC as the consensus authority of the Greek world. Kings, city-states, and colonists consulted her before founding cities, starting wars, or enacting laws. Her answers were famously ambiguous ('a great empire will fall' — whose?), which meant the mechanism was self-correcting: whatever happened, the Oracle was right. Greek cities that ignored her advice were shunned.
Modern analyses suggest the Pythia's trance may have been induced by ethylene gas seeping through the temple's floor fractures — the site sits on two intersecting fault lines. The geology turned out to be doing some of the political work.
