Abstract: The paper is devoted to the curious phenomenon of the Russian Civil War - uprisings of workers against the dictatorship of proletariat, namely, rebellions of mining population of the Urals against the Soviets in the spring and summer of 1918. One of the largest anti-Bolshevik rebellions of mining population in the Urals occurred in June 1918 in the village of Polevskoi factory, located 54 miles south-west of Yekaterinburg. These events are poorly described both in Soviet and modern Russian historiography. Based on the archive documents, memoirs and newspapers, the author reconstructs the events of the mutiny of workers of Polevskoy factory. The paper examines the complex of reasons, which provoked the mutiny against Bolsheviks. The paper also describes consequences of the mutiny, including comparison of the number of victims of red terror with the number of victims of white terror in Polevskoy factory. The author makes a conclusion about the need for national reconciliation and establishment of the general monument to the victims of the Russian Civil War in Polevskoy.
