The development of [https://www.amazon.com/gp/product/B00AQFJFWI/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00AQFJFWI&linkCode=as2&tag=dailyh0c-20&linkId=a4c4bc8ce983a7d39eabf65c43406a44 the electric telegraph ] greatly changed the way diplomacy was conducted in the 19th century. Until that time information was exchanged at the speed of a sailing ship or a galloping horse. During the 1830s and 1840s, inventors working independently in several countries developed workable electric telegraphs, and these devices quickly superseded other technologies with the same name.
By the mid-nineteenth century, telegraphy had acquired its present definition as a device for converting messages into electric impulses that traveled instantaneously by wire to distant receivers, where they were converted back into readable text. European foreign ministries first used telegraphy during the early 1850s, but it did not become an important tool in the diplomacy of the United States until the completion of a successful transatlantic cable in 1866.
