 Consequently, the Eurypontid line was the less senior in status and decision-making,

The untimely death of Aristodemus with other events has served as some basis for dating the reigns of the first nine kings of Sparta in the line known by state definition as the Eurypontid.The Return of the Heracleidae, which is the closest event to a Dorian Invasion available in legend, must coincide with the entry of Aristodemus and his brethren into Arcadia, which, based on the chronology of Eratosthenes, happened 328 years before the generally accepted date of the first year of the first Olympiad, 776 BC.Eratosthenes' date is therefore 1104 BC.
