The citizens of the Baltic Republics (Latvians Lithuanians Estonians Russians Jews Germans
the Poles and the Finns) as well as many other nations of the former USSR experienced serious
difficulties and extreme deprivation during communist rule. They suffered from compulsory
deportation organized by the NKVD-KGB and the Soviet Ministry of Internal Affairs. One of those
initiatives was the so-called 'Spring operation' in 1948. Since the mid-1950s these nations
were gradually rehabilitated. The book contains documents and materials from the main archives
of the Russian Federation including the USSR NKVD-KGB and MVD-MGB secret archives. For many
years these documents had been filed under the sections 'Top secret' and 'Not subject to
disclosure.' Only recently did they become available for Russian historians. (in Russian
