The Diffusion of Sovereignty

Summary

The transmission of ideas about sovereignty and its related practices from one time, place, or intellectual context to another is sometimes characterised as a process of ‘diffusion’ or even ‘contagion’. Intellectual historians may use such metaphors but the explanations they provide are historical, not scientific. Sovereignty was transmitted when European states brought their forms of government to other peoples and when those peoples embraced such forms in declaring their independence from imperial rule. It was also transmitted when the idea of sovereignty was itself transformed in the course of these and other historical passages. In Foundations of Modern International Thought, David Armitage explores some of these historical passages, the outcome of which he sees as the world of sovereign states that defines the modern period and the disappearance of which would signal its end. In doing so, he illuminates the larger enterprise of writing the history of international thought or, as he prefers to call it, international intellectual history, inviting reflection on its relationship to other kinds of historical inquiry and the opportunities and dangers it poses.
