1945–1949 Forced labour camps operated at numerous sites across Bulgaria. The camps were set up near dams under construction, coal mines, and in certain agricultural areas. Some of the most infamous were Bobov Dol, Bogdanov Dol, Rositsa, Kutsian, Bosna, Nozharevo and Chernevo.
1956–1959 A number of new inmates arrived at Belene after the
Hungarian Revolution of 1956 and a crime wave in Sofia early in 1958. Among the figures held at Belene during this period included
Konstantin Muraviev, the last Prime Minister of Bulgaria to hold office before the
Fatherland Front coup of 9 September 1944.
Lovech, a city in north-central Bulgaria, lies at the edge of the
Balkan Mountains. The last and harshest of the major Communist labour camps was set up near an abandoned rock quarry outside the city. Until 1959, the camps had been spread across Bulgaria, but most were closed following
Chervenkov's fall and the inmates transferred to Lovech. The Ministry of the Interior, not the regional authorities, had direct control over the camp. Most Bulgarians were unaware of its existence, but it had a reputation among those who had incurred the state's displeasure as a place from where one might never emerge alive.
1962–1989 The intensity of state repression varied during these years. A Politburo decision in 1962 said that an individual could be imprisoned and assigned to forced labour without a court trial. Repression in this period was of an administrative rather than political nature, targeting those accused of "
social parasitism" or "loose morals", often with information given by "people's organisations" such as the Fatherland Front's neighbourhood sections. In the 1980s, numerous
Turkish Bulgarians were sent to Belene. ==Hierarchy==
