An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via dedicated telecommunication lines or radio. The electromagnetic telegraph is a device for human-to-human transmission of coded messages. The electrical telegraph, or more commonly just telegraph, superseded optical semaphore telegraph systems, such as Claude Chappe's cables designed for communication among the French military, and Friedrich Clemens Gerke for the Prussian military, thus becoming the first form of electrical telecommunications. In a matter of decades after their creation, electrical telegraph networks permitted people and commerce to transmit messages across both continents and oceans almost instantly, with widespread social and economic impacts. The first working electrostatic telegraph was built by the English inventor Francis Ronalds. He laid down eight miles of wire in insulated glass tubing in his garden and connected both ends to two clocks marked with the letters of the alphabet. Electrical impulses sent along the wire were used to transmit messages. He offered his invention to the Admiralty, describing it as "a mode of conveying telegraphic intelligence with great rapidity, accuracy, and certainty, in all states of the atmosphere, either at night or in the day, and at small expense." However, there was little official enthusiasm for his device in the aftermath of the Napoleonic Wars. He published an account of his apparatus in the 1823 Descriptions of an Electrical Telegraph, and of some other Electrical Apparatus.

Samuel Morse receives the patent for the telegraph.

Samuel Morse sends the message "What hath God wrought" (a biblical quotation, Numbers 23:23) from the Old Supreme Court Chamber in the United States Capitol to his assistant, Alfred Vail, in Baltimore, Maryland, to inaugurate the first telegraph line.
