Some of the Achaeans expelled the Ionians from the territory they held in the Peloponnesus, and gave to it the name it afterward retained, of Achaia.

The expelled Ionians took refuge with the Athenians, their kindred race.
The fated house of Pelops swept away by this irruption, Sparta fell to the lot of Procles and Eurysthenes [126], sons of Aristodemus, fifth in descent from Hercules; between these princes the royal power was divided, so that the constitution always acknowledged two kings--one from each of the Heracleid families.

The elder house was called the Agids, or descendants of Agis, son of Eurysthenes; the latter, the Eurypontids, from Eurypon, descendant of Procles.

Although Sparta, under the new dynasty, appears to have soon arrogated the pre-eminence over the other states of the Peloponnesus, it was long before she achieved the conquest even of the cities in her immediate neighbourhood.

The Achaeans retained the possession of Amyclae, built upon a steep rock, and less than three miles from Sparta, for more than two centuries and a half after the first invasion of the Dorians.
And here the Achaeans guarded the venerable tombs of Cassandra and Agamemnon.
