History of International Politics introduces students to the major developments in the international realm since the seventeenth century. It explains how a system of sovereign states developed, first in Europe, and how it became globalized as a result of the rise and fall of Europe’s colonial and imperial endeavors. The system of sovereign states developed historically evolving rules for interaction (diplomatic protocol, international law, a notion of great power responsibility, a forever fragile commitment to human rights, the ‘governmentalization’ of international affairs) which promised a degree of order but nonetheless remained the setting of regular outbreaks of war, some more intense than others, some at the center of the system, some happening in peripheral regions. We will look into the different causes of these wars, explain how they tied in with the system of sovereign states, as well as reflect on the changing form that they took. Finally, we will tackle the problem of decolonization, and, more generally, the return to prominence of non-European countries in international relations.
