Andrei Zhdanov
In April 1948, Zhirmunsky was among the scholars and critics who recanted their supposed "comparativism" and "Veselovskyism" in Andrei Zhdanov′s purge of that year. "Comparativism," or the study of possible borrowing and dissemination of motifs and stories among cultures, was deprecated. In response, Zhirmunsky developed a historical-typological theory, according to which such similarities arose not from historical influence but rather from a similarity of social and cultural institutions.
