Historian and co-host of The Rest Is History podcast Tom Holland joins Amol to explore the history of radical ideas and what it means to be radical today.

Tom explains why Christianity represented such a radical break from what came before, how it shaped secular thought in the West and how that compares to other religions. He also talks about his interest in Ancient Greece and the Roman Empire.

And Tom discusses the phenomenal success of The Rest Is History, which he presents with fellow historian Dominic Sandbrook.
