POWER OVER PEOPLES: Technology, Environments, and Western Imperialism, 1400 to the Present
Princeton, NJ: Princeton University Press, 2009. Spanish edition: Barcelona: Crítica, 2011.

TECHNOLOGY: A World History New York: Oxford University Press, 2009. Arabic edition: Abu Dhabi: Kalima, 2011.

WHEN INFORMATION CAME OF AGE: Technologies of Knowledge in the Age of Reason and Revolution, 1700-1850. New York: Oxford University Press, 2000. Turkish edition: Istanbul: Kitap Yayinevi, 2002.

Before the proliferation of electrical and mechanical information-processing machines of the nineteenth and twentieth centuries, the Enlightenment of the eighteenth century and the revolutionary period that followed stimulated numerous systems for organizing, naming, classifying, storing, presenting, and transmitting information. These systems laid the cultural foundations of our Information Revolution.

THE INVISIBLE WEAPON: Telecommunications and International Politics, 1851-1945. New York: Oxford University Press, 1991.

Before World War I, Great Britain’s hegemony over the world’s telegraph cable network contributed to international antagonisms and led the great powers to subsidize the development of an alternative technology, the radio-telegraph. This book analyzes the development of telecommunications technologies and their relationship to the flow and control of information, to economic and political power in peacetime, and to strategy and events in wartime.

THE TENTACLES OF PROGRESS: Technology Transfer in the Age of Imperialism, 1850-1940. New York: Oxford University Press, 1988. Italian edition: Bologna: Il Mulino, 1991. Japanese edition: Tokyo: Nihon Keizai Hyoronsha, 2005.

This book seeks to explain the paradoxical impact of European colonialism on Asia and Africa, where Western investments and transfers of technology created modern underdeveloped rather than industrial economies. It considers the technologies of shipping, telecommunications, railroads, irrigation, economic botany, mining and metallurgy, and urban public works. It shows that underdevelopment was rooted in the distinction that colonial regimes enforced between the geographic relocation of technologies and their cultural diffusion to Asians and Africans.

THE TOOLS OF EMPIRE: Technology and European Imperialism in the Nineteenth Century. New York: Oxford University Press, 1981. Italian edition: Bologna: Il Mulino, 1984. Spanish edition: Madrid: Alianza Editorial, 1989. Japanese edition: Tokyo: Nihon Keizai Hyoronsha, 1989.

This book is a reinterpretation of the “new imperialism.” It shows that 19th-century European conquests in Asia and Africa resulted not merely from the motivations of various imperialists but also and more importantly from technological innovations that gave Europeans overwhelming power over non-European societies and natural obstacles. These innovations included steam-powered river gunboats, quinine prophylaxis, rapid-firing rifles, steamship lines, submarine cables, and railroads.

EJERCITO Y POLITICA EN ESPAÑA (1866-1898) (The Army and Politics in Spain 1866-1898). Madrid: Editorial Tecnos, 1981.

This book analyzes the causes of recurring military interventions in Spanish politics and the transformation of praetorian ideology from the revolutionary anti-aristocratic liberalism of the mid-nineteenth century to the authoritarian proto-fascist conservatism of the twentieth century. This transformation is traced to the structure of the officer corps, its recruitment, education, professionalization, and internal rivalries, as well as its relations with political parties and civilian society in general.
