Concerning the British side of the equation, Edward VII was in many ways critical in overcoming the hostility of the French public to a closer relationship with Britain, in 1903 he went on a state visit to Paris that enormously altered French attitudes towards the British; when he arrived in Paris it was to crowds shouting “Vivent les Boers!”, by the time he left they were shouting “Vive notre roi!” This trip was hugely beneficial to the Anglo-French rapprochement.*
However in 1900 while travelling through Belgium, the future King Edward VII was nearly assassinated by a Belgian sympathetic of the Boer cause. Jeab Baptiste Sipido fired four shots from a revolver at Edward from point blank range and missed the immense target of the comfortably proportioned royal with every shot! If Sipido had had calmer nerves and a steadier hand Britain’s best diplomatic tool would have been felled on a railway platform in Brussels long before he could overcome the hostility of the Europeans to Britain in the wake of the Boer War.
*For the Americans reading this, Edward’s trip was not his own initiative. It was undertaken at the request of Prime Minister Balfour and the Foreign Secretary, Lord Landsdown; British monarchs in the 20th century served their prime ministers, not the other way around.
