One of the world's greatest authorities on the Middle Ages, Professor Robert Bartlett of St Andrew's University, investigates the intellectual landscape of the medieval world.

In the final programme, Power, Professor Bartlett lays bare the brutal framework of the medieval class system.

The class you were born into determined who you were.
