For the opening of the Northern Pacific Railroad, railroad baron Henry Villard chartered 4 trains to carry VIPs to Montana for the 'Golden Spike' ceremony. And Villard brought VIPs. We're talking about former POTUS Grant, governors of all the states through which the railroad passed, British royalty, European professors, financial barons...possibly the most notable collection of international dignitaries assembled in that century.
He even managed to get the Secretary of State to grant a 1-day release from the Sioux reservation for Chief Sitting Bull to give a 'welcome to the West' speech when the trains reached Bismarck. This was the height of Sitting Bull's status as mythical chief, so the place fell silent when he stood to give his speech.
Instead of reciting the speech he had been given, Sitting Bull said (in Lakota)
"I hate you. I hate all the white people. You are thieves and liars. You have taken away our land and made us outcasts."
Sitting Bull's translator quickly recited the words of the prepared speech.
