It has become all too common for Napoleon Bonaparte's biographers to approach him as a figure to be reviled, bent on world domination, practically a proto-Hitler. Here, after years of study extending even to visits paid to St Helena and 53 of Napoleon's 56 battlefields, Andrew Roberts has created a true portrait of the mind, the life, and the military and above all political genius of a fundamentally constructive ruler. This is the Napoleon, Roberts reminds us, whose peacetime activity produced countless indispensable civic innovations - and whose Napoleonic Code provided the blueprint for civil law systems still in use around the world today.

It is one of the greatest lives in world history, which here has found its ideal biographer. The sheer enjoyment which this book will give anyone who loves history is enormous.
