Lysander as ephor proposed on behalf of Agis that all debts sbould be cancelled and that Laconia should be divided into 19,500 lots, of which 4500 should be given to Spartiates, whose number was to be recruited from the best of the perioeci and foreigners, and the remaining 15,000 to perioeci who could bear arms. The Agiad king Leonidas having prevailed on the council to reject this measure, though by a majority of only one, was deposed in favour of his son-in-law Cleombrotus, who assisted Agis in bearing down opposition by the threat of force.
In his absence the open violence and extortion of Agesilaus, combined with the popular disappointment at the failure of the agrarian scheme, brought about the restoration of Leonidas and the deposition of Cleombrotus, who took refuge at the temple of Apollo at Taenarum and escaped death only at the entreaty of his wife, Leonidas's daughter Chilonis.
As a boy he showed evidence of remarkable talents, and his father Leonidas gave him an excellent education.
Glover (" Leonidas ") attended every performance; the duke of Argyll, Lords Cobham and Lyttelton, Pitt, and several other members of parliament testified their admiration.
While dying, a print of the Leonidas, one of his favourite subjects, was submitted to him.
