This book provides fresh insights into colonial and imperial histories by focusing on spatial appropriations. Moving away from European notions of property, appropriation encompasses the many ways in which social actors consider a space as their own. This space may be physical or immaterial, public or intimate, lived or imagined.In modern empires, spatial appropriations amounted neither to a material and violent dispossession orchestrated by European or Japanese powers, nor to an ongoing and unquestioned resistance by subaltern peoples. They were rather sites of complex interactions, in which the part of each actor owed as much to "foreign" domination as to other political, social, economic and environmental factors.Cutting across common historiographical boundaries, the chapters of this book bring to light the declination and conjugation of various forms of spatial appropriation in the modern imperial age (1820-1960), taking readers on a journey from Russia to China, from the United States to South America, and from the Mediterranean world to Africa.
