Yet telegraphy had a significant impact in Ireland, accelerating internal and external communication times. This article provides the first comprehensive study of telegraphy's expansion, from its arrival in Ireland in the 1850s until the eve of nationalization in 1870. It shows how Ireland's geographical position as a telegraphic gateway to North America, the heavy integration of Ireland's economy into Britain after 1853, and the relationship between telegraphy and the rail network shaped Irish telegraphy in unique ways.
