Reddit reviews Gulag: A History

This was one of a series of uprisings in the Soviet labor camps (known as Gulags) after Stalin's death in 1953. That year, with Stalin's death, marked the beginning of the Gulag's decline.

Quoting from Anne Applebaum's "Gulag: A History", "From 1929, when the Gulag began its major expansion, until 1953, when Stalin died, the best estimates indicate that some eighteen million people passed through this massive system. About another six million were sent into exile."
