 Coupled with increasing reliance on foreign mercenaries and the forces of allied and vassal states, as well as the revolts and civil wars resulting from the widening rift between the civilian bureaucracy in Constantinople and the land-holding military elites (the "dynatoi"), by the time of the Battle of Manzikert in 1071, the Byzantine army was already undergoing a severe crisis and collapsed completely in the battle's aftermath.The Komnenian era saw a brief restoration of the empire's fortunes as the force now known as the 'Komnenian army' was established by Alexios I Komnenos, marking a decisive break with the theme system.The new force was highly centralised in the person of the emperor and the ruling dynasty, and provided an element of stability which characterised the Komnenian restoration.
