This chapter examines the implications of globalization for sovereign statehood. It begins with a discussion of the debate over the consequence of globalization for nation-states, followed by an analysis of the modalities of statehood as they have developed over the past several decades. In particular, it explores how advanced capitalist states are transforming from modern into post-modern states. It also considers the emergence of weak post-colonial states out of special circumstances—the globalization of the institution of sovereignty in the context of decolonization. Furthermore, it looks at modernizing states such as China, India, Russia, and Brazil, which combine features of the modern, post-modern, and weak post-colonial states. The chapter concludes with an overview of changes in statehood that place the discipline of comparative politics in a new setting.
