Peter Ackroyd reveals how the radical ideas of liberty that inspired the French Revolution opened up a world of possibility for great British writers such as William Blake, Samuel Taylor Coleridge and William Wordsworth, inspiring some of the greatest works of literature in the English language. Their ideas are the foundations of our modern notions of freedom and their words are performed by David Tennant, Dudley Sutton and David Threlfall.

As the Industrial Revolution took hold of Britain during the late 18th Century, the Romantics embraced nature in search of sublime experience. But this was much more than just a walk in the country; it was a groundbreaking endeavour to understand what it means to be human. They forged poetry of radical protest against a dark world that was descending upon Britain.

Byron, Keats and Shelley lived short lives, but the radical way they lived them would change the world. At 19, Shelley wrote The Necessity of Atheism - it was banned and burned, but it freed the Romantics from religion. Through their search for meaning in a world without God, they pioneered the notions of free love, celebrity and secular idolatry that are at the centre of modern Western culture. For them poetry became the new religion, a way of reaching eternity.
