This study describes the internment of Bishop Joseph Hlouch of České Budějovice in 1949–1968. Firstly, it deals with his fate in the years 1949–1950 when it was under the control of State Security and an agent of the Government. It consequently describes his isolation in the building of the bishopric over the years 1950–1951 and his removal outside the diocese in March 1952. The main part of the study is devoted to his internment outside the diocese and the internment sites: Kadaň, Myštěves, Šebetov, Paběnice and Koclířov. Archival materials and the testimony of witnesses were primarily made use of for this study.
