What can be called the long twentieth century represents the most miraculous and creative era in human history. It was also the most destructive. Over the past 150 years, modern societies across the globe have passed through an extraordinary and completely unprecedented transformation rooted in the technological developments of the nineteenth century. The World in the Long Twentieth Century lays out a framework for understanding the fundamental factors that have shaped our world on a truly global scale, analyzing the historical trends, causes, and consequences of the key forces at work. Spanning the 1870s to the present, this book explores the making of the modern world as a connected pattern of global developments. Students will learn to think about the past two centuries as a process, a series of political and economic upheavals, technological advances, and environmental transformations that have shaped the long twentieth century.
