Xerxes I of Persia (519 - 465 BCE), also known as Xerxes the Great, was the son of Darius I, the Emperor of Achaemenid Persia, during the Greco-Persian War. Like his father, Xerxes I was a strong ally of proto-Templars.
These proto-Templars aided Xerxes in his suppression of revolts in Egypt and Babylon, as well as his attempted conquest of Greece. In 465 BCE, Xerxes was killed by Darius, later considered to be one of the first proto-Assassins, marking the first recorded use of the Hidden Blade.
