The Soviet famine of 1930–1933 was a famine in the major grain-producing areas of the Soviet Union, including Ukraine and different parts of Russia (Kazakhstan, North Caucasus, Kuban, Volga region, the southern Urals, and western Siberia). Major factors included the forced collectivization of agriculture as a part of the First Five-Year Plan and forced grain procurement from farmers. These factors in conjunction with a massive investment in heavy industry decreased the agricultural workforce. It is estimated that 5.7 to 8.7 million people died from starvation across the Soviet Union. In addition, 50 to 70 million Soviet citizens starved during the famine but ultimately survived.
During this period Soviet leader Joseph Stalin ordered the kulaks (land-owning proprietors) "to be liquidated as a class". As collectivization expanded, the persecution of the kulaks, ongoing since the Russian Civil War, culminated in a massive campaign of state persecution in 1929–1932, including arrests, deportations, and executions of kulaks. Some kulaks responded with acts of sabotage such as killing their livestock and destroying crops designated for consumption by factory workers. Despite the vast death toll in the early stages, Stalin chose to continue the Five Year Plan and collectivization. By 1934, the Soviet Union had established a base of heavy industry, at the cost of millions of lives.
