The primary goal of World Civilizations is to present a TRULY GLOBAL HISTORYone that both discusses the development of the world's leading civilizations and also emphasizes the major stages in the interactions among different peoples and societies. World Civilizations examines all the world's civilizations, including those in the Western tradition but also those civilizations sometimes neglected in world history textsfor example, the nomadic societies of Asia, Latin America, and the nations and states of the Pacific Rim. World Civilizations balances this discussion of independent developments in all the world's major civilizations with comparative analysis of the results of international contact. World Civilizations organizes its presentation of global history into SIX COHERENT TIME PERIODS, with each period defined by the new and parallel patterns that evolved among all or most civilizations during the particular era. The six periods correspond to the six parts of the book. Within each part, the authors identify specific themes that characterize common experiences or common forces in individual societies as well as the new kinds and patterns of global contacts that emerged during the era. Thus, for example, Part I of the book discusses the developmental stage of world history, including the rise of agriculture and the development of civilization. Part II examines the classical era in global history, an era marked by the integration of large regions and diverse groups of people through overarching cultural and political systems. Subsequent parts of the book continue the emphasis on geographic shifts and the intensification of contact among civilizations.
