Was achieve by Queen Victoria On 23 September 1896, who served 64 years on the throne. The 1st Diamond Jubilee was also a reason to party and celebrate and was made the festival of the British Empire, at the time Britain ruled 1/4 of the whole worlds population!! Pretty impressive stuff.
Queen’s Diamond Jubilee procession through London included troops from all over the empire. The parade paused for an open-air service of thanksgiving held outside St Paul’s Cathedral, throughout which Victoria sat in her open carriage, as she was suffering from Rheumatism and was unable to walk up the steps, there is a plack in the place where the carriage stopped. The reported cost of the festival was a whopping £500,000!
