Of these facts most modern historians know but little and Negroes in general almost nothing. For example, how many have ever heard of Al-Bekri, the Arab writer, who in the eleventh century wrote a description of the Western Sudan of such importance that it gained him the title of "The Historian of Negro Land"? How much, by means of research, might be learned of the town of Ghana situate on the banks of the Niger, which the historian Al-Bekri described as a meeting place for commercial caravans from all parts of the world? This town, he said, contained schools and centers of learning. It was the resort of the learned, the rich, and the pious of all nations. Likewise, most of us have never heard perhaps of another Arab writer, Iben Khaldun, who in writing about the middle of the fourteenth century of Melle, another of the kingdoms of the Sudan, reported that caravans from Egypt consisting of twelve thousand laden camels passed every year through one town on the eastern border of the empire on their way to the capital of the nation. The load of a camel was three hundred pounds. 12,000 camel loads amounted, therefore, to something like 1,600 tons of merchandise. At this time we are told that there was probably not a ship in any of the merchant navies of the world which could carry one hundred tons. 250 years later the average tonnage of the vessels of Spain was 300 tons and that of the English much less. The largest ship which Queen Elizabeth had in her navy, the _Great Mary_, had a capacity of a thousand tons; but it was considered an exception and the marvel of the age. Another thing that is not generally known is the importance to which some of these Negro kingdoms of the Western Sudan attained during the middle ages and the first centuries of the modern era. In size and permanency they compared favorably with the most advanced nations of Europe. The kingdom of Melle of which the historian, Iben Khaldun, wrote, had an area of over 1,000 miles in extent and existed for 250 years. It was the first of the kingdoms of the Western Sudan to be received on equal terms with the contemporary white nations. The greatest of all the Sudan states was the kingdom of Songhay which, in its golden age, had an area almost equal to that of the United States and existed from about 750 A.D. to 1591. There is a record of the kings of Songhay in regular succession for almost 900 years. The length of the life of the Songhay empire coincides almost exactly with the life of Rome from its foundation as a republic to its downfall as an empire.
