Poggi presents an extensive conceptual portrait of the state, distinguishing its early characteristics from those which have developed subsequently and are apparent in contemporary states. He reviews the 'historical career' of the state, from the dissolution of feudal forms of rule to the advent of modern, liberal-democratic systems. Poggi also discusses the nature of liberal-democratic regimes, and the distinctive features of the Soviet one-party system. Finally, the chapter discusses the challenges set to the state by contemporary developments in military affairs, in the international economy, and in the ecological sphere.
