This is the introduction to the book titled “Conceptualizing Global History”. The author explains the main topics of the book, and the main findings of each chapter. In addition, the aim is to sketch some of the key problems and possibilities that lie ahead, namely: the historiographic problem, the nature of previous attempts at some form of global vision; the existence of an antecedent Darwinian vision of the “economy of nature”; the challenge of creating institutions other than the nation-state as the subject matter of history; the possibility of global public opinion as an ethical force; the issue of identity; the nature of global communications; the context of global time/space; and the policy implications of global history.
