There is no suggestion of albinism, and the explanation of such strange contrasts must await further exploration in the whole of this borderland of Negroes and Bantus about the divide between the Chad and the Congo basins. The country has until lately been traversed only at rare intervals by pioneers, interested more in political than in anthropological matters. Of the settled and more or less cultured peoples in the Chad basin, the most important are the _Kanembu_[194], who introduce a fresh element of confusion in this region, being more allied in type and speech to the Hamitic Tibus than to the Negro stock, or at least taking a transitional position between the two; the _Kanuri_, the ruling people in Bornu, of somewhat coarse Negroid appearance[195]; and the southern _Baghirmi_, also decidedly Negroid, originally supposed to have come from the Upper Shari and White Nile districts[196]. Their civilisation, such as it is, has been developed exclusively under Moslem influences, but it has never penetrated much below the surface. The people are everywhere extremely rude, and for the most part unlettered, although the meagre and not altogether trustworthy Kanem-Bornu records date from the time of Sef, reputed founder of the monarchy about 800 A.D. Duku, second in descent from Sef, is doubtfully referred to about 850 A.D. Hame, founder of a new dynasty, flourished towards the end of the eleventh century (1086-97), and Dunama, one of his successors, is said to have extended his sway over a great part of the Sahara, including the whole of Fezzan (1221-59). Under Omar (1394-98) a divorce took place between Kanem and Bornu, and henceforth the latter country has remained the chief centre of political power in the Chad basin. A long series of civil wars was closed by Ali (1472-1504), who founded the present capital, Birni, and whose grandson, Muhammad, brought the empire of Bornu to the highest pitch of its greatness (1526-45). Under Ahmed (1793-1810) began the wars with the Fulahs, who, after bringing the empire to the verge of ruin, were at last overthrown by the aid of the Kanem people, and since 1819 Bornu has been ruled by the present Kanemiyin dynasty, which though temporarily conquered by Rabah in 1893, was restored under British administration in 1902[197].
