Simon Schama explores the forces that tore Britain apart during two centuries of dynamic change - transforming outlooks, allegiances and boundaries. From the beginning of July 1637, battles raged on for 200 years - both at home and abroad, on sea and on land, up and down the length of burgeoning Britain, across Europe, America and India. Most would be wars of faith  waged on wide-ranging grounds of political or religious conviction. But as wars of religious passions gave way to campaigns for profit, the British people did come together in the imperial enterprise of 'Britannia Incorporated'.
