Neil Oliver continues his journey through Scotland's past with the story of the Covenanters, whose profound religious beliefs were declared in the National Covenant of 1638. This document licensed revolution, started the Civil War that cost King Charles I his head, cost tens of thousands of Scots their lives and led to Britain's first war on terror.

At the start of the 19th century, everything familiar was swept away. People fled from the countryside into the industrial towns of Scotland's central belt. Rural workers became factory workers - in some of the worst conditions in Europe. This new Scotland became a seedbed of revolution. But it wasn't just force that kept the Scottish people in their place, it was fantasy. Neil Oliver reveals how Sir Walter Scott created so powerful a myth, it haunts the Scots collective imagination to this day.
