Breakdown of Roman society
The breakdown of Roman society was dramatic. The patchwork of petty rulers was incapable of supporting the depth of civic infrastructure required to maintain libraries, public baths, arenas, and major educational institutions. Any new building was on a far smaller scale than before. The social effects of the fracture of the Roman state were manifold. Cities and merchants lost the economic benefits of safe conditions for trade and manufacture, and intellectual development suffered from the loss of a unified cultural and educational milieu of far-ranging connections.
As it became unsafe to travel or carry goods over any distance, there was a collapse in trade and manufacture for export. The major industries that depended on long-distance trade, such as large-scale pottery manufacture, vanished almost overnight in places like Britain. Whereas sites like Tintagel in Cornwall (the extreme southwest of modern day England) had managed to obtain supplies of Mediterranean luxury goods well into the 6th century, this connection was now lost.
Between the 5th and 8th centuries, new peoples and powerful individuals filled the political void left by Roman centralized government. Germanic tribes established regional hegemonies within the former boundaries of the Empire, creating divided, decentralized kingdoms like those of the Ostrogoths in Italy, the Suevi in Gallaecia, the Visigoths in Hispania, the Franks and Burgundians in Gaul and western Germany, the Angles and the Saxons in Britain, and the Vandals in North Africa.
Roman landholders beyond the confines of city walls were also vulnerable to extreme changes, and they could not simply pack up their land and move elsewhere. Some were dispossessed and fled to Byzantine regions; others quickly pledged their allegiances to their new rulers. In areas like Spain and Italy, this often meant little more than acknowledging a new overlord, while Roman forms of law and religion could be maintained. In other areas, where there was a greater weight of population movement, it might be necessary to adopt new modes of dress, language, and custom.
The Muslim conquests of the 7th and 8th centuries of the Persian Empire, Roman Syria, Roman Egypt, Roman North Africa, Visigothic Spain, Sicily and southern Italy eroded the area of the Roman Empire and controlled strategic areas of the Mediterranean. By the end of the 8th century, the former Western Roman Empire was decentralized and overwhelmingly rural.
