This chapter discusses global politics in relation to the phenomenon of globalization. ‘Global politics’ as a field of study encompasses the traditional concerns of International Relations with how states interact under conditions of anarchy, but lays greater emphasis on the role of non-state actors and processes in a globalizing world. The chapter first provides an overview of politics in a globalizing world before explaining the basic distinctions between ‘state’ and ‘nation’ in the context of contemporary global politics. It then considers the variation in state forms and the phenomenon of empire throughout history as well as the historical emergence of the modern state and state system in Europe along with ideas about sovereignty and nationalism against the background of ‘modernity’. It also examines the effective globalization of the European state system through modern imperialism and colonialism and the extent to which these have been productive of contemporary global order.
