Summary
In 480 BC, at the narrow pass of Thermopylae, a vastly outnumbered Greek force prepares to face the advancing army of the Persian king Xerxes. At its head stands Leonidas, king of Sparta, ready to make a final stand that will become one of the most famous moments in ancient history.
In this episode of The Ancients, Tristan Hughes is joined by Dr Andrew Bayliss to peel back the myth and uncover the real story of Leonidas. Tracing Leonidas's origins amid the turbulent politics of Sparta’s Agiad dynasty to his denouement at the hot gates of Thermopylae, they explore Leonidas's journey to power, his dogged defiance against the Persians and what his story reveals about Spartan society, kingship and warfare at the height of the Greco-Persian Wars.
