In the seventh episode of this landmark series charting the story of human civilisation, Andrew Marr tells how Britain's Industrial Revolution created the modern world.
The old agricultural order of aristocratic landowners, serfs and peasant farmers was replaced by a new world of machines, cities and industrialists.
Across the world, many resisted this sweeping change.
From China to America, Russia to Japan, bitter battles were fought between the modernisers and those who rejected the new way of life.
In Europe, new industrial powers competed with each other to create vast empires which dominated the world.
But this intense competition would lead to the industrial-scale slaughter and destruction of the First World War.
