" In general, forced migration study reveals the stunning and gradually increasing adherence of the Soviet system to ethnically rather than socially determined repression criteria (the policy in question reached its apogee during Stalin’s rule). In other words, the state declares its loyalty to international and class awareness publicly, while in practice gravitates towards essentially nationalistic goals and methods.
The deportation of so-called punished peoples can provide a most prominent example of this approach, the deportation itself serving as the punishment. All such peoples were deported not merely from their historical homeland, but also from other cities and districts, as well as demobilized from the army, which shows that such ethnic deportations embraced the entire country (we term this type of repression “total deportation”). Apart from their homeland, the “punished people” were deprived of their autonomy if they had any before, in other words, of their relative sovereignty.
In essence, ten peoples in the USSR were subjected to total deportation. Seven of them—Germans, Karachais, Kalmyks, Ingushetians, Chechens, Balkars, and Crimean Tatars—lost their national autonomy too (their total number amounted to 2 million, and the land populated by them before the deportation exceeded 150,000 square kilometers). According to the criteria formulated above, another three peoples—namely Finns, Koreans, and Meskhetian Turks—fall under the category of “totally deported peoples. "
