The History of Espionage in Ancient Rome
If one is to briefly define the term of espionage, it would be described as the planning, the collection, the analysis, and dissemination of information as related to forces, nations, or coalitions of powers other than one’s own in a military or political setting, in peace time or during war. In the context of Ancient Rome, an interesting question arises in terms what role espionage played in its strategy of defense.
The nature and needs of espionage in Roman times, in an era long before the technological innovations with which we are familiar, were different from those of our own time. Lacking modern means and tools, the art of intelligence among the Romans depended almost exclusively on the human factor. The movement of information in pre-industrial societies was dependent on the movement of people. Moreover, the Roman reality and needs in the realm of intelligence were mainly military in nature. Modern intelligence concerns, such as economic, technological, and scientific espionage as well as counterterrorism, did not exist in Antiquity.

Roman leaders during the period of the Republic did not invest in the development of state-sponsored espionage activities. Even with the advent of the imperial regime, for the Romans, who were militarily the strongest, there was no threatening incentive to develop or utilize alternative methods, such as espionage, to gain a superiority, whether strategic, operational or tactical, that they already possessed. Rome usually resorted to the use of force, or the projection of force. However, by the turn of the second century, faced with growing external threats, the emperors realized that Roman military might had its limits.

Rome’s nemeses
From its foundation by Augustus until the fall of its western part in 476 AD, the Roman Empire was generally threatened on two fronts. In the north, the Empire fought the bellicose Germanic tribes and later confederations of clans, and in the east, it had to confront the Parthians and then the Persians. As the 4th century dawned and Rome’s military superiority began to be seriously challenged, the emperors began to integrate the usefulness of espionage and started to set aside their attitude of indifference toward it that had prevailed during the previous centuries.
There were fundamental differences between the two types of threat posed by the Germanic confederations and the Persians. When one assesses the disparities that existed between the two collectives in terms of administrative organization, urbanization, and the level of centralization of authority, it becomes clear that the Roman authorities had to deal with two very distinct opponents when conducting espionage.
