This article responds to critics of Violence and Civilization in the Western States-Systems (Cambridge University Press, 2016). It provides a rejoinder to challenges to the attempted synthesis of process sociology and the English School analysis of international society. It rebuts the postcolonial contention that the process-sociological analysis of the impact of the European ‘civilizing process’ on the modern states-system is Eurocentric. The article explains how process sociology contributes to the postcolonial critique of ‘civilization’. It concludes by arguing that their combined strengths of the two perspectives can inform the comparative study of Western and non-Western ‘civilizing processes’ and support the development of a more ‘global IR’.
