The Holodomor's Death Toll
The Ukrainian famine—known as the Holodomor, a combination of the Ukrainian words for “starvation” and “to inflict death”—by one estimate claimed the lives of 3.9 million people, about 13 percent of the population. ...a dictator wanted both to replace Ukraine’s small farms with state-run collectives and punish independence-minded Ukrainians who posed a threat to his totalitarian authority. ...the Soviet regime derided the resisters as kulaks—well-to-do peasants, who in Soviet ideology were considered enemies of the state. Soviet officials drove these peasants off their farms by force...
Stalin... already had arrested tens of thousands of Ukrainian teachers and intellectuals and removed Ukrainian-language books from schools and libraries.... ...the Soviet leader used the grain shortfall as an excuse for even more intense anti-Ukrainian repression.
