Diplomacy is conventionally understood as the processes and institutions by which the interests and identities of sovereign states are represented to one another (Wiseman and Sharp, 2017: 297). This chapter makes five inter-related arguments about diplomacy. First, ideas and practices of diplomacy have a multi-millennial history, much longer than is generally thought. Second, this long history has been characterized by perpetual and productive tension between continuity and change, with diplomacy's critics under-estimating its capacity for adaptation. Third, nowadays, traditional diplomacy, as a coherent set of state-based, distinctive practices ï¿½ and the diplomats who carry it out ï¿½ is not diminishing, but growing, in importance. Fourth, diplomacy has become increasingly more ï¿½complexï¿½ than at any time in history ï¿½ we can now claim that in both theory and practice it is more multifaceted, involving four dimensions: traditional bilateral diplomacy (stateï¿½state relations), multilateral diplomacy (three or more states), polylateral diplomacy (stateï¿½non-state relations), and omnilateral diplomacy (relations between non-state entities).1 Fifth, and finally, Diplomatic Studies is now, in the words of the editors of The SAGE Handbook of Diplomacy, a ï¿½rich and expandingï¿½ academic subfield within the field of International Relations (Constantinou et al., 2016a: 1) and indeed within the still broader, global discipline of Political Science.
