He is one of the most famous rulers of the ancient world, remembered for leading a vast Persian invasion of Greece. Yet Xerxes the Great was far more than just a battlefield king.

In this episode of The Ancients, Tristan Hughes is joined by friend of the show Professor Lloyd Llewellyn-Jones to explore the life and reign of Persia's most revered king, who ruled the largest empire the world had yet seen. From his royal upbringing and court politics to religion, monumental building projects and imperial power, this episode goes beyond Greek battle narratives to uncover who Xerxes really was — and how the Achaemenid empire functioned at the height of his power.
