This book explores the critical role of informal diplomats in shaping contemporary global politics as they navigate complex networks of power and influence in the age of strongman leaders.The world of international relations has long been viewed as the domain of state institutions and career diplomats. But in the age of strongman leaders, a new set of actors has emerged as key players in foreign policy: informal diplomats drawn from diasporas, religious communities, and trade networks. Through a collection of essays by historians, anthropologists, and political scientists, this book traces the historical parallels and continuities between these informal diplomats and the diasporic networks that have existed for centuries, shedding light on their critical role in the making of contemporary global politics. By exploring the thick social basis of the strongman-informal diplomat partnership, the contributors offer a fresh perspective on the social worlds that animate international politics today.This innovative volume will be of interest to students and researchers of politics and international relations. This book was originally published as a special issue of History and Anthropology.
