This is a history of the Gulag: a history of the vast network of labor camps that were once scattered across the length and breadth of the Soviet Union, from the islands of the White Sea to the shores of the Black Sea, from the Arctic Circle to the plains of central Asia, from Murmansk to Vorkuta to Kazakhstan, from central Moscow to the Leningrad suburbs. Literally, the word GULAG is an acronym, meaning Glavnoe Upravlenie Lagerei, or Main Camp Administration. Over time, the word "Gulag" has also come to signify not only the administration of the concentration camps but also the system of Soviet slave labor itself, in all its forms and varieties: labor camps, punishment camps, criminal and political camps, women's camps, children's camps, transit camps. Even more broadly, "Gulag" has come to mean the Soviet repressive system itself, the set of procedures that prisoners once called the "meat-grinder": the arrests, the interrogations, the transport in unheated cattle cars, the forced labor, the destruction of families, the years spent in exile, the early and unnecessary deaths.
