:: I am not sure it was unique. For instance, Kuban population (considerable part of which, by the way, were ethnic Ukrainians) was affected at the same extent and according to the same scenario. Generally speaking, the North Caucasus issue is a kind of Catch 22 for Ukrainian nationalists: if they define Holodomor as the famine that affected primarily Ukrainian nationals, the geographical scope of Holodomor has to be expanded beyond the present borders of Ukraine. However, if they go beyond the geographical borders of former Ukrainian SSR they inevitably encounter a vast amount of scholarly works that tell about mortality among Soviet (not Ukrainian) peasantry, so Holodomor becomes indistinguishable from the Soviet Famine of 1932-33.
