About the book: 2020 / Sociology is a science that lives in the present, history in the past. What happens if you look at historical material through the prism of sociological theories? The book you hold in your hands is the realization of this idea. Where, from the point of view of modern stratigraphic theory, should we place the eunuchs of Sultan Suleiman the Magnificent? Upper middle class? What do Indian potlatch and Black Friday have in common? What social elevators operated in the Soviet Union? Is it true that Russians and Ukrainians are fraternal peoples? The use of sociological methods can shed light on these issues. Publishing design preserved in PDF A4 format.
