Islam did not found new states, but modified and united Negro states already ancient; it did not initiate new commerce, but developed a widespread trade already established. It is, as Frobenius says, "easily proved from chronicles written in Arabic that Islam was only effective in fact as a fertilizer and stimulant. The essential point is the resuscitative and invigorative concentration of Negro power in the service of a new era and a Moslem propaganda, as well as the reaction thereby produced."[17]

Early in the eighth century Islam had conquered North Africa and converted the Berbers. Aided by black soldiers, the Moslems crossed into Spain; in the following century Berber and Arab armies crossed the west end of the Sahara and came to Negroland. Later in the eleventh century Arabs penetrated the Sudan and Central Africa from the east, filtering through the Negro tribes of Darfur, Kanem, and neighboring regions. The Arabs were too nearly akin to Negroes to draw an absolute color line. Antar, one of the great pre-Islamic poets of Arabia, was the son of a black woman, and one of the great poets at the court of Haroun al Raschid was black. In the twelfth century a learned Negro poet resided at Seville, and Sidjilmessa, the last town in Lower Morocco toward the desert, was founded in 757 by a Negro who ruled over the Berber inhabitants. Indeed, many towns in the Sudan and the desert were thus ruled, and felt no incongruity in this arrangement. They say, to be sure, that the Moors destroyed Audhoghast because it paid tribute to the black town of Ghana, but this was because the town was heathen and not because it was black. On the other hand, there is a story that a Berber king overthrew one of the cities of the Sudan and all the black women committed suicide, being too proud to allow themselves to fall into the hands of white men.

In the west the Moslems first came into touch with the Negro kingdom of Ghana. Here large quantities of gold were gathered in early days, and we have names of seventy-four rulers before 300 A.D. running through twenty-one generations. This would take us back approximately a thousand years to 700 B.C., or about the time that Pharaoh Necho of Egypt sent out the Phoenician expedition which circumnavigated Africa, and possibly before the time when Hanno, the Carthaginian, explored the west coast of Africa.

By the middle of the eleventh century Ghana was the principal kingdom in the western Sudan. Already the town had a native and a Mussulman quarter, and was built of wood and stone with surrounding gardens. The king had an army of two hundred thousand and the wealth of the country was great. A century later the king had become Mohammedan in faith and had a palace with sculptures and glass windows. The great reason for this development was the desert trade. Gold, skins, ivory, kola nuts, gums, honey, wheat, and cotton were exported, and the whole Mediterranean coast traded in the Sudan. Other and lesser black kingdoms like Tekrou, Silla, and Masina surrounded Ghana.

In the early part of the thirteenth century the prestige of Ghana began to fall before the rising Mandingan kingdom to the west. Melle, as it was called, was founded in 1235 and formed an open door for Moslem and Moorish traders. The new kingdom, helped by its expanding trade, began to grow, and Islam slowly surrounded the older Negro culture west, north, and east. However, a great mass of the older heathen culture, pushing itself upward from the Guinea coast, stood firmly against Islam down to the nineteenth century.

Steadily Mohammedanism triumphed in the growing states which almost encircled the protagonists of ancient Atlantic culture. Mandingan Melle eventually supplanted Ghana in prestige and power, after Ghana had been overthrown by the heathen Su Su from the south.

The territory of Melle lay southeast of Ghana and some five hundred miles north of the Gulf of Guinea. Its kings were known by the title of Mansa, and from the middle of the thirteenth century to the middle of the fourteenth the Mellestine, as its dominion was called, was the leading power in the land of the blacks. Its greatest king, Mari Jalak (Mansa Musa), made his pilgrimage to Mecca in 1324, with a caravan of sixty thousand persons, including twelve thousand young slaves gowned in figured cotton and Persian silk. He took eighty camel loads of gold dust (worth about five million dollars) to defray his expenses, and greatly impressed the people of the East with his magnificence.

On his return he found that Timbuktu had been sacked by the Mossi, but he rebuilt the town and filled the new mosque with learned blacks from the University of Fez. Mansa Musa reigned twenty-five years and "was distinguished by his ability and by the holiness of his life. The justice of his administration was such that the memory of it still lives."[18] The Mellestine preserved its preëminence until the beginning of the sixteenth century, when the rod of Sudanese empire passed to Songhay, the largest and most famous of the black empires.

The known history of Songhay covers a thousand years and three dynasties and centers in the great bend of the Niger. There were thirty kings of the First Dynasty, reigning from 700 to 1335. During the reign of one of these the Songhay kingdom became the vassal kingdom of Melle, then at the height of its glory. In addition to this the Mossi crossed the valley, plundered Timbuktu in 1339, and separated Jenne, the original seat of the Songhay, from the main empire. The sixteenth king was converted to Mohammedanism in 1009, and after that all the Songhay princes were Mohammedans. Mansa Musa took two young Songhay princes to the court of Melle to be educated in 1326. These boys when grown ran away and founded a new dynasty in Songhay, that of the Sonnis, in 1355. Seventeen of these kings reigned, the last and greatest being Sonni Ali, who ascended the throne in 1464. Melle was at this time declining, other cities like Jenne, with its seven thousand villages, were rising, and the Tuaregs (Berbers with Negro blood) had captured Timbuktu.

Sonni Ali was a soldier and began his career with the conquest of Timbuktu in 1469. He also succeeded in capturing Jenne and attacked the Mossi and other enemies on all sides. Finally he concentrated his forces for the destruction of Melle and subdued nearly the whole empire on the west bend of the Niger. In summing up Sonni Ali's military career the chronicle says of him, "He surpassed all his predecessors in the numbers and valor of his soldiery. His conquests were many and his renown extended from the rising to the setting of the sun. If it is the will of God, he will be long spoken of."[19]
