In 1966, during a big campaign coordinated by the Communist Party of Czechoslovakia, around 4,000 young males were forced to cut their hair, often in the cells with the assistance of the state police. On August 19, 1966, during a "safety intervention" organized by the state police, 140 long-haired people were arrested. As a response, the "community of long-haired" organized a protest in Prague. More than 100 people cheered slogans such as "Give us back our hair!" or "Away with hairdressers!". The state police arrested the organizers and several participants of the meeting. Some of them were given prison sentences. According to the newspaper "Mladá fronta Dnes", the Czechoslovak Ministry of Interior in 1966 even compiled a detailed map of the frequency of occurrence of long-haired males in Czechoslovakia. In August 1969, during the first anniversary of the Soviet occupation of Czechoslovakia, the long-haired youth were one of the most active voices in the state protesting against the occupation. Youth protesters have been labeled as "vagabonds" and "slackers" by the official normalized press.
