Historia

World War I was the first major conflict in which new electronic means of transmitting and receiving messages became a major factor in political and military operations. The electric telegraph was developed in the first half of the 19th century, and by 1850, there were several telegraph companies around the world providing a service that allowed virtually instantaneous communication over long distances. This was a major breakthrough, but the telegraph depended on the availability of wires to transmit messages between stations, meaning that if these wires were broken or damaged, communications were cut off.

Late in the 19th century, there was another new development, the telephone, though this too relied on wires to transmit and receive information. At the same time, there was a new invention that provided instant voice and Morse code communication over long distances that did not require wires. Initially called wireless, radio was quickly adopted by armies around the world as a way of providing rapid communication between military units. By the time World War I began in 1914, all the major nations involved had provided their forces with some form of radio equipment.

Of course, this came with a fundamental problem: radio, telephone, and telegraph messages could be intercepted by the enemy, potentially giving them notice of impending operations. To protect these electronic messages from being read by the enemy, armies began to use codes and ciphers to disguise the meaning of messages. Teams were created to devise effective codes and ciphers, and these were quickly followed by other teams whose role was to attempt to break the codes and ciphers used by the other side. As a result, a secret war began, almost completely hidden from public view, as the belligerents devised complex ways of hiding the real meaning of their own messages while simultaneously attempting to understand those of the enemy.
