Komnenian Byzantine Army - Introduction

Introduction

At the beginning of the Komnenian period in 1081, the Byzantine Empire had been reduced to the smallest territorial extent in its history. Surrounded by enemies, and financially ruined by a long period of civil war, the empire's prospects had looked grim. The state lay defenseless before, as the Byzantine army had been reduced to a shadow of its former self. During the 11th century, decades of peace and neglect had reduced the old thematic forces, and the military and political anarchy following the Battle of Manzikert in 1071 had destroyed the professional tagmata, the core of the Byzantine army. At Manzikert, units tracing their lineage for centuries back to the Roman Empire were wiped out, and the subsequent loss of Asia Minor deprived the Empire of its main recruiting ground. In the Balkans, at the same time, the Empire was exposed to invasions by the Norman Kingdom of Sicily, the expansionist activities of the principality of Dioclea (Duklja) and by Pecheneg raids across the Danube.

The Byzantine army's nadir was reached in 1091, when Alexios I could manage to field only 500 soldiers from the Empire's professional forces. These formed the nucleus of the army, with the addition of the armed retainers of Alexios' relatives and the nobles enrolled in the army, plus the substantial aid of a large force of allied Cumans, which won the Battle of Levounion against the Pechenegs (Petcheneks or Patzinaks). Yet, through a combination of skill, determination, and years of campaigning, Alexios, John, and Manuel Komnenos managed to restore the power of the Byzantine Empire by constructing a new army from scratch. This process should not, however, at least in its earlier phases, be seen as a planned exercise in military restructuring. In particular, Alexios I was often reduced to reacting to events rather than controlling them; the changes he made to the Byzantine army were largely done out of immediate necessity and were pragmatic in nature.

The new force had a core of units which were both professional and disciplined. It contained formidable guards units such as the Varangians, the Athanatoi, a unit of heavy cavalry stationed in Constantinople, the Vardariotai and the Archontopouloi, recruited by Alexios from the sons of dead Byzantine officers, foreign mercenary regiments, and also units of professional soldiers recruited from the provinces. These provincial troops included kataphraktoi cavalry from Macedonia, Thessaly, Thrace, and various other provincial forces. Alongside troops raised and paid for directly by the state the Komnenian army included the armed followers of members of the wider imperial family and its extensive connections. In this can be seen the beginnings of the feudalisation of the Byzantine military. The granting of pronoia holdings, where land, or more accurately rights to revenue from land, was held in return for military obligations, was beginning to become a notable element in the military infrastructure towards the end of the Komnenian period, though it became much more important subsequently.

The Komnenian period, despite almost constant warfare, is notable for the lack of military treatise writing, which seems to have petered out during the 11th century. So, unlike in earlier periods, there are no detailed descriptions of Byzantine tactics and military equipment. Information on military matters in the Komnenian era must be gleaned from passing comments in contemporary historical and biographical literature, court panegyrics and from pictorial evidence.
