In 1936 the Great Purge began. Millions of people were arrested or executed, including leading members of the intelligentsia. In July–August of that year, Luzin was criticized in "Pravda" in a series of anonymous articles whose authorship later was attributed to Kolman. It was alleged that Luzin published “would-be scientific papers”, “felt no shame in declaring the discoveries of his students to be his own achievements”, and stood close to the ideology of the “black hundreds”, orthodoxy, and monarchy “fascist-type modernized but slightly.” One of the complaints was that he published his major results in foreign journals.
