How, for just over a century, Britain ensured it would not face another Napoleon Bonaparte--manipulating European powers while building a global maritime empire At the conclusion of the Napoleonic Wars, a fragile peace emerged in Europe. The continent's borders were redrawn, and the French Empire, once a significant threat to British security, was for now cut down to size. But after decades of ceaseless conflict, Britain's economy was beset by a crippling debt. How could this small, insular seapower state secure order across the Channel? Andrew Lambert argues for a dynamic new understanding of the nineteenth century, showing how British policymakers shaped a stable European system that it could balance from offshore. Through judicious deployment of naval power against continental forces, and the defence strategy of statesmen such as the Duke of Wellington, Britain ensured that no single European state could rise to pose a threat, rebuilt its economy, and established naval and trade dominance across the globe. This is the remarkable story of how Britain kept a whole continent in check--until the final collapse of this delicately balanced order at the outset of World War One.
