Dorieus

Dorieus (died c.510 BC; ) was a Spartan prince of the Agiad dynasty who is mentioned several times in Herodotus. The second son of Anaxandridas II, he was the younger half-brother of Cleomenes I and the elder full brother of both Leonidas I and Cleombrotus. He tried to found a colony in Cinyps (Libya) but failed. He tried again to establish a colony in western Sicily, but was killed by the Carthaginians.

==Family== According to Herodotus, Anaxandridas II of Sparta had married his niece and was devoted to her. 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. Anaxandridas refused and the Ephors then proposed that he take a second wife, even though bigamy was hitherto unknown in Sparta. Anaxandridas agreed and, shortly after his second marriage, both of his wives became pregnant. Cleomenes, who was the only child of the second wife, was the first-born. Dorieus was born to the first wife a few months later and she then had Leonidas and Cleombrotus, who may have been twins, in the following year.
