The Soviet famine of 1930–1933 was a famine in the major grain-producing areas of the Soviet Union, including Ukraine and parts of Russia. 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.
