This chapter examines the specificities at work at the international level and their implications for the issue of legitimacy, concentrating on the contemporary context. These specificities have to be understood in relation to the notion and experience of the international community. There are five distinctive features that characterize the international level in connection with the sense of international community. Although the interactions of these characteristics make the international system what it is, this chapter addresses them individually to identify clearly their nature and respective significance for international legitimacy. These features include the ambiguity of the international community; the national bent of international life; cultural diversity and disparity of development; the hegemonic and yet fragmented and contested conception and exercise of power; and the extent to which actors (states and individuals, in particular) have the possibility of ownership—that is, of being represented and of participating at the international level, including in terms of consent.
