The recent history of post-Soviet societies is heavily shaped by the successor nations’ efforts to geopolitically re-identify themselves and to reify certain majorities in them. As a result of these fascinating processes, various new ideologies have appeared. Some are specific to the post-Soviet space while others are comparable to ideational processes in other parts of the world. In this collected volume, an international group of contributors delves deeper into recent theoretical constructions of various post-Soviet majorities, the ideologies that justify them, and some respectively formulated policy prescriptions. The first part analyzes post-Soviet state-builders’ fixation on certain constructed majorities as well as on these imagined communities’ symbolic self-identifications, in- or outward othering, and national languages. The second part deals specifically with post-Soviet ideas of sovereigntism and the way they define majorities as well as imply changes in internal and external policies and legal systems. These processes are analyzed in comparison to similar phenomena in Western societies. The book’s contributors include (in the order of their appearance): Natalia Kudriavtseva, Petra Colmorgen, Nadiia Koval, Ivan Gomza, Augusto Dala Costa, Roman Horbyk, Yana Prymachenko, Yuliya Yurchuk, Oleksandr Fisun, Nataliya Vinnykova, Ruslan Zaporozhchenko, Mikhail Minakov, Gulnara Shaikhutdinova, and Yurii Mielkov.
