Gorgo, Queen of Sparta

Gorgo (/ˈɡɔːrɡoʊ/; Greek: Γοργώ [ɡorɡɔ͜ɔ́]; fl. 480 BC) was the daughter and the only known child of Cleomenes I, King of Sparta (r. 520–490 BC) during the 6th and 5th centuries BC. She was the wife of King Leonidas I, Cleomenes' half-brother, who fought and died in the Battle of Thermopylae. Gorgo is noted as one of the few female historical figures actually named by Herodotus, and was known for her political judgement and wisdom. She is notable for being the daughter of a king of Sparta, the wife of another, and the mother of a third. Her birth date is uncertain, but is most likely to have been between 518 and 508 BC, based on Herodotus' dating (Histories 5.51).

Her father Cleomenes was the eldest-born son of the previous Agiad king, Anaxandridas II, and succeeded his father at his death; however, he had three paternal half-brothers, of whom the eldest, Dorieus, would cause him some trouble. The other two half-brothers were Leonidas I and Cleombrotus. All four were sons of Anaxandridas II, one of the dual kings of Sparta of the Agiad house.

According to one version (Herodotus's Histories, 5.4), Gorgo's grandfather Anaxandridas II was long married without children, and was advised to remarry (i.e. take a second wife) which he did. His second wife gave birth to the future Cleomenes I who was thus his eldest son; however, his first wife also became pregnant, and eventually had three sons, including Leonidas I. This version is however not supported by other sources, which imply that Cleomenes was either born by the king's first marriage or by a non-marital alliance. Most historians favor Herodotus because he is the earliest source. In either case, there appears to have been some tension between the eldest son and his half-brothers, resolved only by the former's death (or murder) and the accession of Leonidas I (at once his half-brother and his son-in-law).
