With the dissolution of the Soviet Union and the demise of the Cold War's bipolar world order, Soviet successor states on the Russian periphery found themselves in a geopolitical vacuum, and gradually evolved into a specific buffer zone throughout the 1990s. Focusings on these areas of the post-Soviet realm, this collected volume examines how they have faced multidimensional challenges while pursuing both geopolitics and their place in the world economy. The first section reviews the fundamental elements of the formation of national identity in light of the geopolitical situation both past and present. This includes an examination of the relative strength and shifting dynamics of statehood, the impacts of imperial nationalism, and the changes in language use from the early-modern period onwards. The second section examines the (trans)formation of the identities of small nations living at the forefront of Tsarist Russian geopolitical expansion, in particular in Central Asia, the Caucasus, and the Southern Steppe. Finally, in the third section, the contributors discuss the fate of groups whose settlement space was divided by the external boun?daries of the Soviet Union, a reality that resulted in the diverging developmental trajectories of the otherwise culturally similar communities on both sides of the border. In these imperial peripheries, Soviet authority gave rise to specifically Soviet national identities amongst groups such as the Azeris, Tajiks, Karelians, Moldavians, and others. The book comprises more than 30 primarily original maps, graphs, and tables and will be of great use not only for human geographers (particularly political and cultural geographers) and historians, but also for those interested in contemporary issues in social science.
