In the early 1970s, Britain seemed to be tottering on the brink of the abyss. Under Edward Heath, the optimism of the '60s had become a distant memory. Now the headlines were dominated by strikes and blackouts, unemployment and inflation. As the world looked on in horrified fascination, Britain seemed to be tearing itself apart. And yet, amid the gloom, glittered a creativity and cultural dynamism that would influence our lives long after the nightmarish '70s had been forgotten.

Britain's empire has gone. Our manufacturing base is a shadow of its former self; the Royal Navy has been reduced to a skeleton. In military, diplomatic and economic terms, we no longer matter as we once did. And yet there is still one area in which we can legitimately claim superpower status: our popular culture.

The Roman Republic was the most remarkable state in history. What began as a small community of peasants camped among marshes and hills ended up ruling the known world. Rubicon paints a vivid portrait of the Republic at the climax of its greatness - the same greatness which would herald the catastrophe of its fall. It is a story of incomparable drama.

Something has gone really wrong in Britain. Our economy has tanked, our freedoms are shrinking, and social divisions are growing. Our politicians seem most interested in their own careers, and much of the media only make things worse. We are living in a country almost unrecognisable from the one that existed a decade ago. But whose fault is it really? Who broke Britain and how did they do it?

Now, on the book's 40th anniversary, this fully revised and expanded edition illuminates further the fascinating and mysterious centuries between the Romans and the Norman Conquest.
