had to go through the rigorous education system of Sparta, called the agoge. Despite his disability, he brilliantly completed the training, which massively enhanced his prestige, especially after he became king. Indeed, as heirs-apparent were exempted of the agoge, very few Spartan kings had gone through the same training as the citizens; another notable exception was Leonidas, the embodiment of the "hero-king". Between 433 and 428, Agesilaus also became the younger lover of Lysander, an aristocrat from the circle of Archidamos, whose family had some influence in Libya. Spartan prince Little is known of Agesilaus' adult life before his reign, principally because Xenophon—his friend and main biographer—only wrote about his reign. Due to his special status, Agesilaus likely became a member of the Krypteia, an elite corps of young Spartans going undercover in Spartan territory to kill some helots deemed dangerous. Once he turned 20 and became a full citizen, Agesilaus was elected to a common mess, presumably that of his elder half-brother Agis II, who had become king in 427, of which Lysander was perhaps a member. Agesilaus probably served during the Peloponnesian War (431–404) against Athens, likely at the Battle of Mantinea in 418. Agesilaus married Kleora at some point between 408 and 400. Despite the influence she apparently had on her husband, she is mostly unknown. Her father was Aristomenidas, an influential noble with connections in Thebes. Thanks to three treaties signed with Persia in 412–411, Sparta received funding from the Persians, which it used to build a fleet that ultimately defeated Athens. This fleet was essentially led by Lysander, whose success gave him an enormous influence in the Greek cities of Asia as well as in Sparta, where he even schemed to become king. In 403 the two kings, Agis and Pausanias, acted together to relieve him from his command. Reign Accession to the throne (400–398 BC) Agis II died while returning from Delphi between 400 and 398. After his funeral, Agesilaus contested the claim of Leotychidas, the son of Agis II, using the widespread belief in Sparta that Leotychidas was an illegitimate son of Alcibiades—a famous Athenian statesman and nephew of Pericles, who had gone into exile in Sparta during the Peloponnesian War, and then seduced the queen. The rumours were strengthened by the fact that even Agis only recognised Leotychidas as his son on his deathbed. Diopeithes, a supporter of Leotychidas, however quoted an
