They inhabited the region of Achaea in the northern Peloponnese, and played an active role in the colonization of Italy, founding the city of Kroton.
[3][4][5][6] In the Classical era the Achaeans inhabited the region of Achaea in the northern Peloponnese, and later established colonies in Italy including Kroton and Sybaris.
[14] Herodotus described them as unified nation composed of 12 city-states: Pellene, Aegeira, Aeges, (Achaea) Boura, Helike, Aegion, Rhypes, Patrai, Pherae, Olenos, Dyme and Tritaia.
[18] Both Herodotus and Pausanias recount the legend that the Achaeans (referring to the tribe of the Classical period) originally dwelt in Argolis and Laconia.
[21][22] Pausanias says that 'Achaean' was the name of those Greeks originally inhabiting the Argolis and Laconia, because they were descended from the sons of the mythical Achaeus, Archander and Architeles.
