No national feelings or particular line of policy connected Heraclius with Constantinople, and his frequent absence during the active years of his life indicates that, as long as his personal energy and health allowed him to direct the public administration, he considered the constant residence of the emperor in that city injurious to the general interests of the state. On the other hand, Carthage was, at this time, peculiarly a Roman city; and in actual wealth, in the numbers of its independent citizens, and in the activity of its whole population, was probably inferior to no city in the empire. It is not surprising, therefore, that Heraclius, when compelled to suppress the public distributions of bread in the capital, to retrench the expenditure of his court and make many reforms in his civil government, should have wished to place the imperial treasury and his own resources in a place of greater security, before he engaged in his desperate struggle with Persia. The wish, therefore, to make Carthage the capital of the Roman Empire may, with far greater probability, be connected with the gallant project of his eastern campaigns, than with the cowardly or selfish motives attributed to him by the Byzantine writers. Carthage offered military resources for recovering possession of Egypt and Syria, of which we can only now estimate the extent by taking into consideration the expedition that placed Heraclius himself on the throne. Many reasons connected with the constitution of the civil government of the empire might likewise be adduced as tending to influence the preference. THE PROVINCES UNDER HERACLIUS Egypt, from its wonderful natural resources and its numerous and industrious population, had long been the most valuable province of the empire. It poured a very great portion of its gross produce into the imperial treasury; for its agricultural population, being destitute of all political power and influence, were compelled to pay, not only taxes, but a tribute, which was viewed as a rent for the soil, to the Roman government. At this time, however, the wealth of Egypt was on the decline. The circumstances which had driven the trade of India to the north, had caused a great decrease in the demand for the grain of Egypt on the shores of the Red Sea, and for its manufactures in Arabia and Ethiopia. The canal between the Nile and the Red Sea, whose existence is intimately connected with the prosperity of these countries, had been neglected during the government of Phocas.
