II., the 30th king of Sparta of the Agid line, was of the royal race, though not in the direct male line. He was also the son-in-law of Leonidas II., in whose place he was made king by the party of Agis IV. about 243 B. C. On the return of Leonidas, Cleombrotus was deposed and banished to Tegea, about 240 B. C. [AGIS IV.] He was accompanied into exile by his wife Cheilonis, through whose intercession with her father his life had been spared, and who is mentioned as a conspicuous example of conjugal affection. He left two sons, Agesipolis and Cleomenes, of whom the former became the father and the latter the guardian of AGESIPOLIS III. (Plut. Agis 11, 16_18; Paus. 3.6; Plb. 4.35; Manso, Sparta, 3.1, pp. 284, 298.)
