14 June, 1966
Riots by construction workers on Dam Square in Amsterdam during the Holland Festival. Heavy riots broke out on 13 June 1966, when construction workers, who were not members of a trade union, were told that their vacation bonus would be cut down with 2%. During the riots, one of the construction workers died from a heart attack. The Dutch newspaper De Telegraaf, however, reported the following day that he had died from wounds caused by a stone thrown by one of his comrades. Enraged by this one-sided coverage of the story, the workers assaulted De Telegraaf building on the Nieuwezijds Voorburgwal, and the riots came thus to be known as De Telegraaf Riots (De Telegraafrellen).
