Editing Xerxes I (section)

===Accession to the throne===
While Darius was preparing for another war against Greece, a revolt began in Egypt in 486BC due to heavy taxes and the deportation of craftsmen to build the royal palaces at Susa and Persepolis. The king was required by Persian law to choose a successor before setting out on dangerous expeditions; when Darius decided to leave for Egypt (487–486BC), he prepared his tomb at [[Naqsh-e Rustam]] (five kilometers from his royal palace at Persepolis) and appointed Xerxes, his eldest son by [[Atossa]], as his successor. However, Darius could not lead the campaign due to his failing health; he died in October 486&nbsp;BC at the age of 64.{{sfn|Dandamayev|1989|pp=178–179}}

[[Artobazan]] claimed that he should take the crown as the eldest of all Darius' children, while Xerxes argued for his own claim on the grounds that he was the son of Atossa, the daughter of Cyrus, and that Cyrus had won the Persians their freedom. Xerxes' claim was supported by a Spartan king in exile who was present in Persia at the time, the [[Eurypontid]] king [[Demaratus]], who also argued that the eldest son did not universally have the best claim to the crown, citing Spartan law, which stated that the first son born while the father is king was the heir to the kingship.<ref>[[Herodotus]] 7.1–5</ref> Some modern scholars also view the unusual decision of Darius to give the throne to Xerxes as a result of his consideration of the particular prestige that Cyrus the Great and his daughter Atossa enjoyed.<ref>[[#refshabani-xerxes|R. Shabani]] Chapter I, p. 15</ref> [[Artobazan]] was born to "Darius the subject", while Xerxes was the eldest son "[[born in the purple]]" after Darius' rise to the throne. Furthermore, while Artobazan's mother was a commoner, Xerxes' mother was the daughter of the founder of the Achaemenid Empire.<ref>[[#ref|Olmstead: The history of Persian empire]]</ref>

Xerxes was crowned and succeeded his father in October–December 486&nbsp;BC<ref name=chi-v2>[[#refchi-v2|''The Cambridge History of Iran'']] vol. 2. p. 509.</ref> when he was about 32 years old.{{sfn|Dandamayev|1989|p=180}} The transition of power to Xerxes was smooth, due again in part to the great authority of Atossa<ref name=atossa-EI>Schmitt, R.
