Trudging through mud in sub-zero temperatures, digging the earth with their bare hands and heaving huge rocks with the most primitive of tools, these horrifying photos have revealed life inside Joseph Stalin's gulag prisons, where people were worked to death in Soviet labour camps through the mid-1900s.
This year marks 100 years since the 1917 Russian Revolution, which led to Vladimir Lenin taking control of the Soviet Union. When Lenin died in 1924, Stalin rose to power and became the state's authoritarian leader.
Between 1929 and the year of Stalin's death in 1953, 18million men and women were transported to Soviet slave labour camps in Siberia and other outposts of the Red empire - many of them never to return.
Communist regimes have murdered more people than the Italian fascists, the German Nazis, and the Japanese militarists combined. In other words, more people have been annihilated by the Communists (100 million) than died in the Second World War (65 million).
