s were characterized as either frontier garrisons to police border provinces and keep the peace in fringe settlements or mobile field armies to confront attacking enemy forces in mass engagements. The first known written reference to Limitanei was recorded in 363 AD.

, and designated with the task of harassing or delaying invading enemies and otherwise buying time for a larger, more capable force of comitatenses to arrive and destroy an invading force. The limitanei were used in as stationary roles along the frontier and were not expected to fight major battles. Because they were not involved in heavy fighting, these soldiers were granted plots of land to cultivate, which essentially turned them into part time soldiers/farmers. In this way, the limitanei were used to defend the empire in times of war as well as provide additional food for soldiers. The comitatenses represented the bulk of the Roman legion

, Celtic, Iranic, and Eastern neighbours, collectively referred to as Barbarians by the Romans themselves.

As the soldier profession is often not productive (prolonged periods of training with only occasional conflict), empires had long resorted to this principle of "military colonists." Thus, the late Roman empire adopted the system of limitanei (frontier-colonist-soldier) for economic reasons. By employing soldiers in this way, Rome was able to capitalize on their knowledge of warfare as well benefit from the agriculture produced by limitanei. Many scholars believe that empires stationed these soldiers on the outskirts of empires as a first line of defense against raiding barbarians tribes.

Although these military reforms brought about a more effective defensive army than the previous arrangement had, it did have its pitfalls.

) resented being reduced to trivial home guard duties and acting more similarly to an urban police force until such a time that a serious enough threat presented itself at a nearby border, when they were called upon for duty.

The quality of these border troops declined because the limitanei had to live in poor conditions in impoverished and isolated towns, unlike their well-off counterparts the comitatenses, who were typically assigned to more urban and prosperous areas of the empire.
