Frederick the Great and his uncle George II were confederates in the Seven Years' War, Queen Charlotte, the consort of George III, was the aunt of the Prussian queen Louisa, and since the Battle of Waterloo the victory was commemorated each year at a banquet in a hall in Windsor Castle built specially for this purpose. King Frederick William was the godfather of the Prince of Wales and went to England personally in 1842; in 1844 William visited the English court, and his wife Augusta came there two years later. In 1850 William stood godfather to Albert and Victoria's third child, in 1853 Augusta became the godmother of their fourth child. When William and Augusta came to London in 1851 to see the Great Exhibition, Albert cautiously put forward his favourite plan for the first time, a proposal to join their children in marriage: young Frederick, called Fritz, who was to become crown prince and then emperor Frederick III, and the princess royal Victoria, the eldest and by far most talented child of the British royal couple.
