son of Anaxandrides king of Sparta, who became regent after the battle of Thermopylae. On the approach of the Persians he was deterred from building a wall across the isthmus of Corinth, by an eclipse of the sun. He died in the 75th Olympiad, and was succeeded by Pleistarchus, the infant son of Leonidas.

CLEOMEROTUS I., son of Pausanias king of Sparta, and brother to Agesipolis I., whom he succeeded on the throne. He was entrusted with the conduct of three successive expeditions against the Boeotians; and to avoid the suspicion of treachery which his former hesitancy and ill-success had inspired at home, he rashly gave battle to Epaminondas at Leuctra on disadvantageous ground, and fell in the engagement, B.C. 371. He was succeeded by his son Agesipolis II.

CLEOMEROTUS II., king of Sparta during the exile of his father-in-law Leonidas II. On the recall of Leonidas (240 B.C.) he was in turn deposed and banished to Tegea, whither he was accompanied by Cheilonis his wife.
