On March 10, 1966, Princess Beatrix married the German Claus von Amsberg in the city of Amsterdam, where Provo, a one-year-old anarchist youth movement, provoked lawful authorities, the monarchy, and “the mindless masses” in a playful and imaginative way. All day long there were riots and a few smoke bombs were thrown.
Provo organized various playful actions but they were not appreciated by the police. The Provotarian sector organization Oranje Komitee De Parel van de Jordaan issued a warning that evil people would administer LSD to the mounted police's horses.
