Documentary series. As a partner in the British Empire, Scotland began the 20th century with an advanced economy and a world beating heavy industry. But come the closing decades, its sense of Britishness was in doubt and a Scottish Parliament sat in Edinburgh for the first time since 1707. Charting what was probably one of Scotland's darkest centuries, Neil Oliver discovers a country driven to self-determination through a series of economic crises so deep, that her most striking export became its own disillusioned population.
