The Byzantine army, modeled after the Roman army, evolved over time to combat threats to the empire. It expanded and contracted, fought in major campaigns, and was one of the strongest military forces in the region. It used a legion system of heavy infantry, light cavalry, and archers, and foreign mercenaries. It reorganized to meet a growing Persian threat, adopted new weapons and better armor, and reconquered much of the territory held by the Roman Empire. The empire slowly contracted, leading to a reorganization of the military administration, and the creation of a professional army based in Constantinople. Under the Komnenian dynasty, the army was reconstituted with professional soldiers and conscripted troops, emphasizing training and equipment. Despite its eventual downfall, the Byzantine army represented one of the most powerful military forces of its time.
The Byzantine army was a military force organized by the Byzantine Empire between AD 330 and AD 1453. Originally modeled after the Roman army, this force evolved over time to combat threats to the empire. The size of the army expanded and contracted during the life of the empire and they fought in several major campaigns in the area around the Mediterranean Sea. For much of the empire’s existence, the Byzantine army was one of the strongest and best organized military forces in the region.
The Byzantine army was a direct successor to the Roman armies that occupied the eastern half of the empire prior to its division in the early 4th century AD. Early Byzantine forces used a legion system of heavy infantry supplemented with light cavalry and archers. Barbarians and foreign mercenaries have made up a significant portion of the military throughout its existence.
As time went on, the Byzantine army was reorganized to meet a growing Persian military threat, eventually abandoning the legion system and relying more heavily on heavy cavalry in the field. The army also adopted new weapons and better defensive armor. Under Justinian I, the Byzantine army managed to reconquer much of the territory held by the Roman Empire in North Africa and Southern Europe, although this period would represent the culmination of the empire’s expansion.
After Justinian’s death, the empire slowly began to contract, eventually spurring a reorganization of the military administration. The empire was divided into five themes based on previous armies, and land within these themes was given to soldiers in exchange for service, similar to the European feudal system. Subsequent revolts led to the creation of a professional army based in Constantinople and known as the tagma. This period saw the army adopt a largely defensive stance against hostile neighbors and a gradual decline in effectiveness.
Under the Komnenian dynasty in the 11th and 12th centuries, the army was reconstituted with professional soldiers from the capital and conscripted troops from the surrounding provinces. The Byzantine military of this period emphasized training and equipment. It also became highly centralized and dependent on the imperial leadership. This dependency would eventually lead to the empire’s demise in 11, because the succeeding dynasty was unable to provide strong military leadership.
While the Byzantine military enjoyed mixed fortunes during its long life, it managed to reinvent itself to meet new challenges and defend the city of Constantinople from successive waves of invaders for more than 1,000 years. During this time, the military was able to project power into North Africa, Europe and the Middle East. Despite its eventual downfall, the Byzantine army represented one of the most powerful military forces of its time.
