The losses resulting from ecclesiastical quarrels, the sanguinary revolutions of political factions, the ravages of Crusaders and the pestilence were speedily supplied from the cities of Greece and the colonies of Asia Minor. The heterogeneous elements of its population, thus recruited from so many sources, early caused it to assume the appearance and the character of the most cosmopolitan of cities; and as the capital was the type of the entire region subject to the sovereign, it has been remarked, not incorrectly, that the Byzantine Empire was a government without a nation. So marked, however, was the religious and intellectual debasement of contemporaneous Europe that the weakness and crimes of the Greek emperors passed unnoticed amidst the recognized superiority of the civilization which their wanton extravagance polluted. The extent and magnitude of their commerce, the splendor of their embassies, the munificence with which they rewarded their allies, afforded the most exaggerated ideas of their importance and power. The pomp which invested their presence concealed the deplorable conditions under whose restraints they were compelled to direct the affairs of their empire. The political imbecility of the Greeks was, therefore, not visible to their neighbors. These observed only the gorgeous theatrical effects which sustained the prestige of a decaying monarchy, and the alliance of the princes of Constantinople was solicited alike by the khalifs of Bagdad, Cairo, and Cordova, by the emperors of the West, and by the kings of England. In the social polity of the Greeks the court was everything and the people nothing. The natural law of progress, by which man is encouraged to accumulate wealth by the knowledge that he can enjoy it unmolested, and is impelled to intellectual pursuits through the hope of political advancement,--a law practically annulled by the Cæsars of Rome,--was entirely abolished under the emperors of Byzantium. Little security could be expected from a government which attempted to extort from the wretched peasant, whose harvests had been swept away by the barbarian, the same tax demanded from the prosperous merchant, and made no allowance for the destitution for which its own incapacity and corruption were responsible.
