Tom Holland and Iszi Lawrence continue to explore the historical connections behind today's headlines.

Today - with a resurgence in nationalism from Beijing to Barcelona and with flag-flying dominating the world news, Tom and Iszi look into the origins of this powerful force.

Author, critic and long-time scholar of fairy tales, Marina Warner, recalls regimes who have used them as a political tool for their own sinister ends.

And with the possibility of a second referendum in Scotland being discussed, Tom goes to the spot where Robert the Bruce was buried to consider the challenges of teaching a balanced history curriculum in schools.
