This chapter gives an overview of the structure of the book, detailing how it is organized around a series of contests over the expressions of sovereignty made by these four pseudo-states. In identifying the similarities in how these contests over sovereignty played out, inside and outside Africa, this chapter lays the foundation for the argument that Katanga, Rhodesia, Transkei, and Bophuthatswana can be usefully seen as linked parts in a larger story. In this formulation, their individual quests for diplomatic recognition and international acceptance were all in pursuit of a common ideological project, one born out of a reaction to the rapid decolonization of the African continent and the triumph of anti-colonial African nationalism. All four of them harnessed important transnational right-wing networks across Africa, Europe, and North America that were energized by the dissolution of the European empires, the rise of the Afro-Asian Bloc, postcolonial migrations, and the international civil rights movements. Each of these aspirant states ultimately failed to achieve international acceptance and faced collective nonrecognition, which reflected the larger regional and global importance of these challenges to the postcolonial African state system.
