Alexander Sedyakin was executed during a campaign that occurred during what years?
Great Purge The Great Purge or the Great Terror (Russian: Большо́й терро́р ) was a campaign of political repression in the Soviet Union which occurred from 1936 to 1938. It involved a large-scale purge of the Communist Party and government officials, repression of peasants and the Red Army leadership, widespread police surveillance, suspicion of "saboteurs", "counter-revolutionaries", imprisonment, and arbitrary executions. Mobile gas vans were invented to execute people without trial. In Russian historiography, the period of the most intense purge, 1937–1938, is called Yezhovshchina (Russian: Ежовщина ; literally, "Yezhov phenomenon", commonly translated as "times of Yezhov" or "doings of Yezhov"), after Nikolai Yezhov, the head of the Soviet secret police, the NKVD, who was later killed in the purge. It has been estimated that 600,000 people died at the hands of the Soviet government during the Purge.
Mallian Campaign The Mallian Campaign was conducted by Alexander the Great from November 326 to February 325 BC, against the Malli of the Punjab. Alexander was defining the eastern limit of his power by marching down-river along the Hydaspes to the Acesines (now the Jhelum and Chenab), but the Malli and the Oxydraci combined to refuse passage through their territory. Alexander sought to prevent their forces meeting, and made a swift campaign against them which successfully pacified the region between the two rivers. Alexander was seriously injured during the course of the campaign, almost losing his life.
