The paper offers a micro‑history study of the case of insulting the Orthodox priest Aleksey Orlov by the Jewish merchants Isai and Leonty Prezman and Moise Haimovich in Tomsk, 1858–1863. The paper draws upon the archival sources from the State Historical Archive of the Omsk Region. It explores the materials of the trial, the correspondence between the Governor‑General of Western Siberia and the Tomsk Civil Governor, copies of the Senate’s decisions, numerous petitions of the defendants and their relatives. The author studies the patterns of interaction between the Jewish minority and the secular and Orthodox authorities at different levels, as well as the various groups of the Siberian society. The study reveals special features specific to Siberia and to regional mentality of the Siberian Jews.
