The Arab conquest not only put an end to the political power of the Romans, which had lasted seven hundred years, but it also soon rooted out every trace of the Greek civilisation introduced by the conquests of Alexander the Great, and which had flourished in the country for upwards of nine centuries. The year after Syria was subdued, Mesopotamia was invaded, and proved an easy conquest.
As soon as the Arabs had completed the conquest of Syria, they invaded Egypt. The emperor Heraclius sent an Armenian governor, Manuel, with a body of troops, to defend the province. The fortune of the Arabs again prevailed, and the Roman army was defeated. If the accounts of historians can be relied on, it would seem that the population of Egypt had suffered less from the vicious administration of the Roman Empire, and from the Persian invasion, than any other part of their dominions; for about the time of its conquest by the Romans it contained seven millions and a half, exclusive of Alexandria, and its population was now estimated at six millions.
COMBAT OF ROMAN GALLEYS
A year after Amru had completed the conquest of Egypt, he had established the water communication between the Nile and the Red Sea: and, by sending large supplies of grain by the canal to Suez, he was able to relieve the inhabitants of Mecca, who were suffering from famine. After more than one interruption from neglect, the policy of the caliphs of Baghdad allowed it to fall into decay, and it was filled up by Almansor, 762-767 A.D.
[640-646 A.D.]
As soon as the Arabs had settled the affairs of the native population, they laid siege to Alexandria. This city made a vigorous defence, and Heraclius exerted himself to succour it; but, though it held out for several months, it was at last taken by the Arabs, for the troubles which occurred at Constantinople after the death of Heraclius prevented the Roman government from sending reinforcements to the garrison. The confidence of the Saracens induced them to leave a feeble corps for its defence after they had taken it; and the Roman troops, watching an opportunity for renewing the war, recovered the city, and massacred the Mohammedans, but were soon compelled to retire to their ships, and make their escape. In less than five years (646 A.D.), a Roman army, sent by the emperor Constans under the command of Manuel, again recovered possession of Alexandria, by the assistance of the Greek inhabitants who had remained in the place; but the Mohammedans soon appeared before the city, and, with the assistance of the Egyptians, compelled the imperial troops to abandon their conquest.[39] The walls of Alexandria were thrown down, the Greek population driven out, and the commercial importance of the city destroyed. Thus perished one of the most remarkable colonies of the Greek nation, and one of the most renowned seats of that Greek civilisation of which Alexander the Great had laid the foundations in the East, after having flourished in the highest degree of prosperity for nearly a thousand years.
The conquest of Cyrenaīca followed the subjugation of Egypt as an immediate consequence. The Greeks are said to have planted their first colonies in this country 631 years before the Christian era, and twelve centuries of uninterrupted possession appeared to have constituted them the perpetual tenants of the soil; but the Arabs were very different masters from the Romans, and under their domination the Greek race soon became extinct in Africa. It is not necessary here to follow the Saracens in their farther conquests westward. In a short time both Latin and Greek civilisation was exterminated on the southern shores of the Mediterranean.
Though Heraclius failed in gaining over the Syrians and Egyptians, yet he succeeded completely in reuniting the Greeks of Asia Minor to his government, and in attaching them to the empire. His success may be estimated from the failure of the Saracens in their attacks on the population of this province. The moment the Mohammedan armies were compelled to rely on their military skill and religious enthusiasm, and were unable to derive any profit from the hostile feeling of the inhabitants to the imperial government, their career of conquest was checked; and almost a century before Charles Martel stopped their progress in the west of Europe, the Greeks had arrested their conquests in the East, by the steady resistance which they offered in Asia Minor.
