African religion does not, however, stop with fetish, but, as in the case of other peoples, tends toward polytheism and monotheism. Among the Yoruba, for instance, Frobenius shows that religion and city-state go hand in hand.
"The first experienced glance will here detect the fact that this nation originally possessed a clear and definite organization so duly ordered and so logical that we but seldom meet with its like among all the peoples of the earth. And the basic idea of every clan's progeniture is a powerful God; the legitimate order in which the descendants of a particular clan unite in marriage to found new families, the essential origin of every new-born babe's descent in the founder of its race and its consideration as a part of the God in Chief; the security with which the newly wedded wife not only may, but should, minister to her own God in an unfamiliar home."[55]
The Yoruba have a legend of a dying divinity. "This people ... give evidence of a generalized system; a theocratic scheme, a well-conceived perceptible organization, reared in rhythmically proportioned manner."
Miss Kingsley says, "The African has a great Over God."[56] Nassau, the missionary, declares, "After more than forty years' residence among these tribes, fluently using their language, conversant with their customs, dwelling intimately in their huts, associating with them in the various relations of teacher, pastor, friend, master, fellow-traveler, and guest, and in my special office as missionary, searching after their religious thought (and therefore being allowed a deeper entrance into the arcana of their soul than would be accorded to a passing explorer), I am able unhesitatingly to say that among all the multitude of degraded ones with whom I have met, I have seen or heard of none whose religious thought was only a superstition.
"Standing in the village street, surrounded by a company whom their chief has courteously summoned at my request, when I say to him, 'I have come to speak to your people,' I do not need to begin by telling them that there is a God. Looking on that motley assemblage of villagers,—the bold, gaunt cannibal with his armament of gun, spear, and dagger; the artisan with rude adze in hand, or hands soiled at the antique bellows of the village smithy; women who have hasted from their kitchen fire with hands white with the manioc dough or still grasping the partly scaled fish; and children checked in their play with tiny bow and arrow or startled from their dusty street pursuit of dog or goat,—I have yet to be asked, 'Who is God?'"[57]
The basis of Egyptian religion was "of a purely Nigritian character,"[58] and in its developed form Sudanese tribal gods were invoked and venerated by the priests. In Upper Egypt, near the confines of Ethiopia, paintings repeatedly represent black priests conferring on red Egyptian priests the instruments and symbols of priesthood. In the Sudan to-day Frobenius distinguishes four principal religions: first, earthly ancestor worship; next, the social cosmogony of the Atlantic races; third, the religion of the Bori, and fourth, Islam. The Bori religion spreads from Nubia as far as the Hausa, and from Lake Chad in the Niger as far as the Yoruba. It is the religion of possession and has been connected by some with Asiatic influences.
From without have come two great religious influences, Islam and Christianity. Islam came by conquest, trade, and proselytism. As a conqueror it reached Egypt in the seventh century and had by the end of the fourteenth century firm footing in the Egyptian Sudan. It overran the central Sudan by the close of the seventeenth century, and at the beginning of the nineteenth century had swept over Senegambia and the whole valley of the Niger down to the Gulf of Guinea. On the east Islam approached as a trader in the eighth century; it spread into Somaliland and overran Nubia in the fourteenth century. To-day Islam dominates Africa north of ten degrees north latitude and is strong between five and ten degrees north latitude. In the east it reaches below the Victoria Nyanza.
Christianity early entered Africa; indeed, as Mommsen says, "It was through Africa that Christianity became the religion of the world. Tertullian and Cyprian were from Carthage, Arnobius from Sicca Veneria, Lactantius, and probably in like manner Minucius Felix, in spite of their Latin names, were natives of Africa, and not less so Augustine. In Africa the Church found its most zealous confessors of the faith and its most gifted defenders."[59]
The Africa referred to here, however, was not Negroland, but Africa above the desert, where Negro blood was represented in the ancient Mediterranean race and by intercourse across the desert. On the other hand Christianity was early represented in the valley of the Nile under "the most holy pope and patriarch of the great city of Alexandria and of all of the land of Egypt, of Jerusalem, the holy city, of Nubia, Abyssinia, and Pentapolis, and all the preaching of St. Mark." This patriarchate had a hundred bishoprics in the fourth century and included thousands of black Christians. Through it the Cross preceded the Crescent in some of the remotest parts of black Africa.
All these beginnings were gradually overthrown by Islam except among the Copts in Egypt, and in Abyssinia. The Portuguese in the sixteenth century began to replant the Christian religion and for a while had great success, both on the east and west coasts. Roman Catholic enterprise halted in the eighteenth century and the Protestants began. To-day the west coast is studded with English and German missions, South Africa is largely Christian through French and English influence, and the region about the Great Lakes is becoming christianized. The Roman Catholics have lately increased their activities, and above all the Negroes of America have entered with their own churches and with the curiously significant "Ethiopian" movement.
