By the end of the nineteenth century the global telegraph network had connected all continents and brought distant people into direct communication 'at the speed of thought' for the first time. Roland Wenzlhuemer here examines the links between the development of the telegraph and the paths of globalization, and the ways in which global spaces were transformed by this technological advance. His groundbreaking approach combines cultural studies with social science methodology, including evidence based on historical GIS mapping, to shed new light on both the structural conditions of the global telegraph network and the historical agency of its users. The book reveals what it meant for people to be telegraphically connected or unconnected, how people engaged with the technology, how the use of telegraphy affected communication itself and, ultimately, whether faster communication alone can explain the central role that telegraphy occupied in nineteenth-century globalization.

London is one of the best connected cities in the world-from a structural as well as from a functional perspective. The central finance and business districts of the metropolis feature both an extraordinarily well-developed information infrastructure and an unusually high concentration of information-dependent businesses. Outside these core districts, however, global connectivity drops massively. An informational divide rips through the global city. This paper builds on a comparatively recent understanding of 'new electronic communications technologies as part of a long history of rich and often wayward social practices' (Thrift) and seeks to provide a historical perspective on the emergence of global connectivity patterns. Due to its longstanding history as a global financial centre and its central position in the global and domestic telegraph network of the nineteenth century, London will provide a suitable case study to examine the long-term interplay of socioeconomic and structural patterns in the creation of global information networks.

Interregional communication has been a key constituent of the process of globalization since its very origins. For most of its history, information has moved between world regions and along the routes according to the rationales established by interregional trade and migration. The dematerialization of telecommunication in the late eighteenth and nineteenth century eventually detached long-distance information transmission from transport and transformed the global communication structure. New communication centres (and new peripheries) emerged. Some regions moved closer to the global data stream than others. It is still unclear how such different degrees of global connectivity impacted on local development. This essay contributes to the identification and valuation of global communication centres and peripheries in order to provide suitable candidates for future case studies. To this end, statistical data on the development of domestic telegraph networks in selected countries has been analysed and interpreted. In a second step, Social Network Analysis methods have been employed to measure the centrality of almost three hundred cities and towns in the European telecommunication network of the early twentieth century.‘You cannot not communicate.’Paul Watzlawick

The study of transregional connections is central to the field of global history. This article reflects on the idea of connections from a conceptual viewpoint and treats them as mediators. This will be exemplified by studying the spatial and temporal dimensions of transoceanic steamship passages. The lives of crew and passengers did not go on ‘stand-by’ during such a passage. The case of the flight and eventual capture of Hawley Harvey Crippen will serve as a case in point. Suspected of murder in London, Crippen tried to escape to North America by transatlantic steamer. The captain, however, recognized the fugitive and informed both authorities and media. The ship, whose movements across the Atlantic contributed to the establishment of global connections, thus became tightly entangled in a global media landscape, with newspapers and readers from all over the globe focusing their attention on the small shipboard community. Simultaneously, the steamer became a profoundly secluded place for its passengers, who were cut off from the media flurry surrounding them. The article shifts the principal perspective of the murder case from a terracentric notion of history to a more sea-based narrative. It offers a new historical interpretation of the events and at the same time reconsiders the analytical concept of connections in a broader historical context.
