Xerxes was crowned King of Persia after the death of his father Darius. He was the first son born after Darius had ascended the throne.
As was common in Persia with the change of rulers, Xerxes was immediately challenged by revolts within his kingdom. He began with interventions in Egypt and Babylon followed by a full invasion of Greece.
Xerxes completed the unfinished building project left by Darius which includes the Gate of all nations and Hall of a Hundred Columns at Persepolis and the Susa Gate and palace.
