Next in the town's history, another important event happened during the Mycenean period, when the Dorians tried to invade and take the control over the town.
Herodotus speaks of Ionians, Dorians , Herakleeidai, and Akhaians among the Greeks, that is, with aggregative self-definitions.
But Pindar and others also assign the foundation of the games to Herakles, as noted above, an attempt, some have suggested, to assert a clearly Dorian claim to the foundation of the games, since Herakles is a Dorian hero.
When Herodotus writes about Ionians, Dorians , Herakleeidai, Akhaians he also mentions myths of origins in relation to genealogies of the eponymous ancestors Helen, Doros, Aiolos, Ion, and Akhaios.
But, around 1100 BCE, the Mycenaeans were invaded by barbarians called Dorians and all their advances disappeared.
