The Kazakh famine of 1919–1922 had the same reasons as the Russian famine of 1921-1922: severe intermittent drought conditions, aggravated by the Russian Civil War and the policy of tax in kind adopted by the Soviet government at the time. At the time, Kazakh lands were part of the Turkestan Autonomous Soviet Socialist Republic and (since 1920) of the misnamed Kirghiz Autonomous Socialist Soviet Republic. By to some demographic estimates, 400 thousand Kazakhs, amounting 18.5% of the population, died in the famine.
