have been hemmed in by a Muhammadan population for centuries. An unsuccessful attempt to convert the Bambara was made by a marabout, named ʻUmaru Kaba, early in the twentieth century. This man had founded a new religious confraternity, connected with the Qādiriyyah, and having failed to attract his co-religionists to it, he turned his attention to the pagan Bambara, and endeavoured to convert them to Islam and enrol them in his order. He seemed to be on the road to success and had already converted a pagan village in the province of Sansanding, when the chief of the province drove the missionary across the frontier and ordered the newly-converted Bambara to return to their old religious observances. [1058] Where intermarriages with such races as Arabs and Berbers have been frequent, a steady process of infiltration has gone on, and this, added to the propagandist activities of those races—Fulbe, Hausa and Mandingo—who have distinguished themselves for their zeal on behalf of their religion, would have contributed to the more rapid growth of a Muhammadan population, had it not been for the internecine wars that caused one Muhammadan state to work the destruction of another. Melle rose on the ruins of Ghāna in the thirteenth century, to be crushed at the beginning of the sixteenth by Songhay, which in its turn was desolated by the Moors a century later. As these Muhammadan empires declined, with the wholesale massacres characteristic of warfare in the Sudan, fetishism regained much of the ground it had lost; and as in the Christian, so in the Muhammadan world, there have been periods when missionary zeal has sunk to a low ebb, and Muhammadans in some parts of the Sudan have been content to leave the paganism that surrounded them untouched by any proselytising efforts.
