History of Greece - Byzantine Empire (4th Century - 1453)

1453)

The history of the East Roman or Byzantine Empire is described by Byzantinist August Heisenberg as the history of "the Christianized Roman empire of the Greek nation". The division of the empire into East and West and the subsequent collapse of the Western Roman Empire were developments that constantly accentuated the position of the Greeks in the empire and eventually allowed them to become identified with it altogether. The leading role of Constantinople began when Constantine the Great turned Byzantium into the new capital of the Roman Empire, from then on to be known as Constantinople, placing the city at the center of Hellenism a beacon for the Greeks that lasted to the modern era.

The figures of Constantine the Great and Justinian dominated during 324–610. Assimilating the Roman tradition, the emperors sought to offer the basis for later developments and for the formation of the Byzantine Empire. Efforts to secure the borders of the Empire and to restore the Roman territories marked the early centuries. At the same time, the definitive formation and establishment of the Orthodox doctrine, but also a series of conflicts resulting from heresies that developed within the boundaries of the empire marked the early period of Byzantine history.

In the first period of the middle Byzantine era (610–867) the empire was attacked both by old enemies (Persians, Lombards, Avars and Slavs) as well as by new ones, appearing for the first time in history (Arabs, Bulgars). The main characteristic of this period was that the enemy attacks were not localized to the border areas of the state but they were extended deep beyond, even threatening the capital itself. At the same time, these attacks lost their periodical and temporary character and became permanent settlements that transformed into new states, hostile to Byzantium. Those states were referred by the Byzantines as Sclavinias.

Changes were also observed in the internal structure of the empire which was dictated by both external and internal conditions. The predominance of the small free farmers, the expansion of the military estates and the development of the system of themes, brought to completion developments that had started in the previous period. Changes were noted also in the sector of administration: the administration and society had become immiscibly Greek, while the restoration of Orthodoxy after the iconoclast movement, allowed the successful resumption of missionary action among neighboring peoples and their placement within the sphere of Byzantine cultural influence. During this period the state was geographically reduced and economically damaged, since it lost wealth-producing regions; however, it obtained greater lingual, dogmatic and cultural homogeneity.

From the late 8th century, the Empire began to recover from the devastating impact of successive invasions, and the reconquest of Greece began. Greeks from Sicily and Asia Minor were brought in as settlers. The Slavs were either driven out or assimilated and the Sclavinias were eliminated. By the middle of the 9th century, Greece was Greek again, and the cities began to recover due to improved security and the restoration of effective central control.
