Sparta, it is true, still continued to retain her independence, but without a shadow of her former greatness and power. The primitive simplicity of Spartan manners had been completely destroyed by the collection of wealth into a few hands, and by the consequent progress of luxury. The number of Spartan citizens had been reduced to 700; but even of these there were not above a hundred who possessed a sufficient quantity of land to maintain themselves in independence. The young king, Agis IV., who succeeded to the crown in 244, attempted to revive the ancient Spartan virtue, by restoring the institutions of Lycurgus, by cancelling all debts, and by making a new distribution of lands; and with this view he relinquished all his own property, as well as that of his family, for the public good. But Agis perished in this attempt, and was put to death as a traitor to his order. A few years afterwards, however, Cleomenes, the son of Leonidas, succeeded in effecting the reforms which had been contemplated by Agis, as well as several others which regarded military discipline. The effect of these new measures soon became visible in the increased success of the Spartan arms. Aratus was so hard pressed that he was compelled to solicit the assistance of the Macedonians. Both Antigonus Gonatas and his son Demetrius II.--who had reigned in Macedonia from 239 to 229 B.C. were now dead, and the government was administered by Antigonus Doson, as guardian of Philip, the youthful son of Demetrius II. Antigonus Doson was the grandson of Demetrius Poliorcetes, and the nephew of Antigonus Gonatas. The Macedonians compelled him to accept the crown; but he remained faithful to his trust as guardian of Philip, whose mother he married; and though he had children of his own by her, yet Philip succeeded him on his death. It was to Antigonus Doson that Aratus applied for assistance; and though Cleomenes maintained his ground for some time, he was finally defeated by Antigonus Doson in the fatal battle of Sellasia in Laconia (B.C. 221). The army of Cleomenes was almost totally annihilated; he himself was obliged to fly to Egypt; and Sparta, which for many centuries bad remained unconquered, fell into the hands of the victor. The succession of Macedonian kings from Alexander the Great to the extinction of the monarchy will be seen from the following table:--
