Britain and Germany were once natural allies, with closely related royal families. Where did it all go wrong? Received wisdom says with the accession of Wilhelm II in 1888. In fact, as this provocative history demonstrates, the hostility went back a full half century before 1914, to the 1864 German-Danish war. And when economic collapse hit the victorious Reich in 1873, the catastrophe seemed so inexplicable that it could only be blamed on the perfidious English policy of free trade.
