At length the all-conquering followers of Mahomet issued forth, and, after desolating the fine African provinces which were subject to Rome, some of their adventurous bands seem to have penetrated in various quarters into the interior, and, occupying the banks of one of the finest rivers, to have planted themselves, in greater or less numbers, beyond the immense desert which forms the northern boundary of interior Africa. But it should be remembered, that while the Mahometans, who overran the various provinces of both the eastern and western empires, became civilized by the nations they subdued, as Rome had been before by her conquest of Greece, so that they soon attained to a great degree of knowledge and refinement; the tribes which planted themselves in Africa, finding only nations as illiterate and as unpolished as themselves, retained all their original barbarism; while their ferocious tempers and habits, and their intolerant tenets, led them to keep down their negro subjects in a state of grievous subjection, and prevented that secure enjoyment of person and property which prompts men to industry, by securing to them the enjoyment and use of what they have acquired, and is indispensably necessary for enabling the mind to exercise its powers with freedom. Here, perhaps however, the first faint beams of knowledge and civilization shot into the darkness of the negro nations; and it is remarkable, that, barbarous as were the first Mahometan settlers of interior Africa, and hostile to all improvement as is the genius of Mahometanism, yet such is the effect of any regular government, that in those districts in which the Mahometans either possess the entire government, or a very considerable influence over it, there were many centuries ago great and populous cities, provinces not ill cultivated, and a considerable degree of social order and civilization. It may therefore be boldly affirmed, that the interior, to which may be added the western coast of Africa to the south of the great desert, never enjoyed any of that intercourse with more polished nations, without which no nation on earth is known ever to have attained to any high degree of civilization; and that, contemptuously as we and the other civilized nations of Europe now speak of the Africans, had we been left in their situation, we should probably have been not more civilized than themselves.
