This book seeks to overcome the tension between 'western' and 'non-western' categories and tools in the study of global history, showing how most western approaches to the social sciences and history have developed through transnational and colonial interactions. Offering a transnational and global history of the main tools we have to understand the word and its transformations over the last three centuries,Tensions of Social Historyexplores the construction of archives and historical memory, the making of statistics and their use in politics, the identification of social actors, and the emergence of key social theories. Providing key insights into how to write history and develop social sciences in the global era while avoiding eurocentrism and cultural exceptionalism, this ambitious book shows how global history is made of encounters rather than confrontations between civilizations.
