• Ahasuerus

• Start — no reference given. The year Ahasuerus's reign began is the year Darius' reign ended = 3476
• End — no reference given. The year Ahasuerus's reign ended is the year his reign began (3476) + the length of his reign (21) years = 3497

START:Most scholars identify Ahasuerus in Esther with Xerxes I (486–465 BCE). The description of his vast empire (127 provinces in EST 1:1) and opulent court aligns with Herodotus’ portrayal of Xerxes’ wealth and campaigns (Histories 7–9). The Greek form of Xerxes (Xerxes) matches the Hebrew Achashverosh via the Old Persian Xšayārša. The account of the book of Esther, with its Persian court intrigue and reference to Susa (Shushan), fits Xerxes I’s reign. No ancient sources explicitly name Xerxes as Ahasuerus, but the linguistic and historical fit is strong. The absence of precise dates in Esther allows flexibility, but Xerxes I is the consensus. Xerxes I preceded Artaxerxes I, his son. Thus, Ahasuerus (Xerxes I) in Esther is not the same person as Artaxerxes in Ezra or Nehemiah. EXTRA-BIBLICAL SOURCES: Babylonian contract tablets dated to Darius I’s reign (522–486 BCE) cease in late 486 BCE (around October/November), and tablets dated to “Year 1 of Xerxes, King of Persia and Media” begin shortly thereafter, marking his accession in late 486 BCE. The transition is seamless, indicating Xerxes’ immediate recognition as king. [Shulman date p143] [Ussher date p119] END:*EXTRA-BIBLICAL SOURCES: - Babylonian contract tablets dated to “Year 21 of Xerxes” appear until mid-465 BCE (around August), after which tablets dated to “Year 1 of Artaxerxes” begin, indicating Xerxes’ death in the summer of 465 BCE. Some tablets note a brief period of instability, possibly due to the assassination. - Ptolemy’s Canon lists Xerxes I’s reign as 21 years, ending in 465 BCE, with Artaxerxes I succeeding him. - Herodotus’ Histories does not explicitly describe Xerxes’ death, as his account focuses on the Greek wars (480–479 BCE) and ended before 465 BCE. - In his Persica, preserved in fragments by later authors like Photius, Ctesias describes Xerxes’ assassination by a courtier, Artabanus, in a palace conspiracy. - In his Library of History (Book 11.69), Diodorus provides a later account of Xerxes’ assassination, attributing it to Artabanus, who briefly usurped power before Artaxerxes I’s rise. - The Persepolis Fortification and Treasury Tablets are administrative records continue under Xerxes until his death until mid-465 BCE, after which Artaxerxes I’s tablets begin. This transition supports Xerxes’ death in 465 BCE. [Shulman date p143]
