As Scotland stands on the brink of a momentous decision, Andrew Marr explores the writers who have reflected, defined and challenged Scottish national identity over the last three hundred years. Andrew examines the life of Walter Scott, a prolific novelist and poet who wrote swashbuckling tales of romance and derring-do, which sold by the bucket load, both north and south of the border. But he is less well known as a political fixer who believed in a proud Scotland inside the United Kingdom. He brought King George IV to Scotland and swathed him in tartan, helping to create an enduring myth of Scotland as a land of romance populated by a brave race doing brave deeds, all clad in the kilt. An image that centuries later, Scotland is still trying to shake.
