This was in some respects true, for Cyrus had been the founder of the empire and the legitimate monarch, while Darius had no hereditary claims. He was originally a noble, of high rank, indeed, but not of the royal line; and he had been designated as Cyrus's successor in a time of revolution, because there was, at that time, no prince of the royal family who could take the inheritance. Those, therefore, who were disposed to insist on the claims of a legitimate hereditary succession, might very plausibly claim that Darius's government had been a regency rather than a reign; that Xerxes, being the oldest son of Atossa, Cyrus's daughter, was the true representative of the royal line; and that, although it might not be expedient to disturb the possession of Darius during his lifetime, yet that, at his death, Xerxes was unquestionably entitled to the throne.
Influence of Atossa.
There was obviously a great deal of truth and justice in this reasoning, and yet it was a view of the subject not likely to be very agreeable to Darius, since it seemed to deny the existence of any real and valid title to the sovereignty in him. It assigned the crown, at his death, not to his son as such, but to his predecessor's grandson; for though Xerxes was both the son of Darius and the grandson of Cyrus, it was in the latter capacity that he was regarded as entitled to the crown in the argument referred to above. The doctrine was very gratifying to the pride of Atossa, for it made Xerxes the successor to the crown as her son and heir, and not as the son and heir of her husband. For this very reason it was likely to be not very gratifying to Darius. He hesitated very much in respect to adopting it. Atossa's ascendency over his mind, and her influence generally in the Persian court, was almost overwhelming, and yet Darius was very unwilling to seem, by giving to the oldest grandson of Cyrus the precedence over his own eldest son, to admit that he himself had no legitimate and proper title to the throne.
The Spartan fugitive.
His views of the succession.
While things were in this state, a Greek, named Demaratus, arrived at Susa. He was a dethroned prince from Sparta, and had fled from the political storms of his own country to seek refuge in Darius's capital. Demaratus found a way to reconcile Darius's pride as a sovereign with his personal preferences as a husband and a father. He told the king that, according to the principles of hereditary succession which were adopted in Greece, Xerxes was his heir as well as Cyrus's, for he was the oldest son who was born after his accession. A son, he said, according to the Greek ideas on the subject, was entitled to inherit only such rank as his father held when the son was born; and that, consequently, none of his children who had been born before his accession could have any claims to the Persian throne. Artobazanes, in a word, was to be regarded, he said, only as the son of Darius the noble, while Xerxes was the son of Darius the king.
The decision.
Death of Darius.
In the end Darius adopted this view, and designated Xerxes as his successor in case he should not return from his distant expedition. He did not return. He did not even live to set out upon it. Perhaps the question of the succession had not been absolutely and finally settled, for it arose again and was discussed anew when the death of Darius occurred. The manner in which it was finally disposed of will be described in the next chapter.
