the success of the Komnenoi was their establishment of a reconstructed Byzantine army. The new military system which they created is known as the Komnenian army. From c. 1081 to c. 1180, the Komnenian army played an important role in providing the empire with a period of security that enabled Byzantine civilization to flourish. The new force was both professional and disciplined. It contained formidable guards units such as the Varangian Guard, the 'Immortals' (a unit of heavy cavalry) stationed in Constantinople and the Archontopouloi, recruited by Alexios from the sons of dead Byzantine officers, and also levies from the provinces. These levies included Kataphraktoi cavalry from Macedonia, Thessaly and Thrace, and various other provincial forces such as Trebizond Archers from the Black Sea coast of Asia Minor and the Vardariots, a cavalry unit recruited from Christianised Magyars from the Vardar valley. 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 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. In 1097, the Byzantine Army numbered around 70,000 men altogether. By the closing years of the 1180-era, and the death of Manuel Komnenos, whose frequent campaigns had been on a grand scale the army was probably considerably larger. During the reign of Alexius I, the field army numbered around 20,000 men which was increased to about 30,000 men in John II's reign. By the end of Manuel I's reign the Byzantine field army had risen to 40,000 men. Under John II, a Macedonian division was maintained, and new native Byzantine troops were recruited from the provinces. As Byzantine Asia Minor began to prosper under John and Manuel, more soldiers were raised from the Asiatic provinces of Neokastra, Paphlagonia and even Seleucia (in the south east). Soldiers were also drawn from defeated peoples, such as the Pechenegs (cavalry archers), and the Serbs, who were used as settlers stationed at Nicomedia. Native troops were organised into regular units and stationed in both the Asian and European provinces. Komnenian armies were also often reinforced by allied contingents from Antioch, Serbia
