Map "Telegraph map of Europe. Edited according to the latest special telegraph maps of all European states in the Central Telegraph Office Berlin."

Within a few years, a dense telegraph network had been established in Germany that not only connected most cities, but extended across the entire European continent. For the first time in history, real-time communication was possible—even across countries and continents. This had widespread effects on the economy and society—just like smartphones and the Internet are having today. This outline map shows the telegraph lines and stations in Europe in 1858.
