This chapter explains why the state and sovereignty are relevant to the study of politics. It first provides an empirical typology of the state, ranging from the minimalist night-watchman state, approximated to by nineteenth-century capitalist regimes at one end of the spectrum, to the totalitarian state of the twentieth century at the other. It then examines the distribution of power in the state by focusing on three major theories of the state: pluralism, elitism, Marxism, as well as New Right theory. The chapter seeks to demonstrate that the theories of the state identified can also be critiqued normatively, so that pluralism, for instance, can be challenged for its divisive character, as exemplified by identity politics. It then goes on to review different views about what the role of the state ought to be, from the minimalist state recommended by adherents of classical liberalism, to the pursuit of distinctive social objectives as recommended, in particular, by proponents of communitarianism. Finally, it discusses empirical and normative challenges to the state and asks whether the state’s days are numbered.
