Dorieus

Dorieus (died c.510 BC; Ancient Greek: Δωριεύς) was a Spartan prince of the Agiad dynasty who is mentioned several times in Herodotus.

For a long time, the marriage was childless and Sparta's Council of the Ephors, fearing that the line of Eurysthenes would expire, asked Anaxandridas to divorce his wife and remarry.

Dorieus challenged the decision but was over-ruled even though, Herodotus says, he was the finest young man of his generation whereas Cleomenes was not right in his head and was on the verge of madness.

[3][5] Dorieus returned to Sparta but soon heard about land in western Sicily which, he was advised, rightly belonged to the Heracleidae, from whom his family claimed descent.

Instead it was Dorieus' younger brother Leonidas who succeeded Cleomenes as king and assumed the mantle of an heroic figure by his deeds in the Persian Wars.
