Magna Carta has inspired and motivated and radicalised countless people all over the world for centuries. It's a document about administration and process, but it has echoed down through the centuries.

Visiting the places where history was made, examining the documents that tell the story, and speaking to word-leading experts, Dan finds the answers to burning questions: how was King John brought to his knees? What did the rebel barons want? And why is Magna Carta still remembered to this day?
