About the book: year / In a collective monograph written by historians Perm State Technical University, together with archival workers, an attempt was made to reconstruct in detail the mass operations of 1937–1938. on the territory of the Kama region. Based on archival sources, it is shown that at the local level there were practically no differences between repressive campaigns.

This allows us to clarify ideas about great terror and rethink established research approaches to its study..
