Ethnical and Political Relations in the Chad Basin.
Kanembu; Kanuri[188]; Baghirmi, Mosgu. Round about the shores of Lake Chad are grouped three other historical Muhammadan nations, the Kanembu ("People of Kanem") on the north, the Kanuri of Bornu on the west, and the Baghirmi on the south side. The last named was conquered by the Sultan of Wadai in 1871, and overrun by Rabah Zobeir, half Arab, half Negro adventurer, in 1890. But in 1897 Emile Gentil[189], French commissioner for the district, placed the country under French protection, although French authority was not firmly established until the death of Rabah and the rout of his sons in 1901. At the same time Kanem was brought under French control, and shortly afterwards Bornu was divided between Great Britain, France and Germany.
In this region the ethnical relations are considerably more complex than in the Hausa States. Here Islám has had greater obstacles to contend with than on the more open western plateaux, and many of the pagan aborigines have been able to hold their ground either in the archipelagos of Lake Chad (Yedinas, Kuri, Buduma[190]), or in the swampy tracts and uplands of the Logon-Shari basin (Mosgu, Mandara, Makari, etc.).
The Aborigines.
Islám and Heathendom.
Slave-Hunting.
It was also the policy of the Muhammadans, whose system is based on slavery, not to push their religious zeal too far, for, if all the natives were converted, where could they procure a constant supply of slaves, those who accept the teachings of the Prophet being ipso facto entitled to their freedom? Hence the pagan districts were, and still are, regarded as convenient preserves, happy hunting-grounds to be raided from time to time, but not utterly wasted; to be visited by organised razzias just often enough to keep up the supply in the home and foreign markets. This system, controlled by the local governments themselves, has long prevailed about the borderlands between Islám and heathendom, as we know from Barth, Nachtigal, and one or two other travellers, who have had reluctantly to accompany the periodical slave-hunting expeditions from Bornu and Baghirmi to the territories of the pagan Mosgu people with their numerous branches (Margi, Mandara, Makari, Logon, Gamergu, Keribina) and the other aborigines (Bede, Ngisem, So, Kerrikerri, Babir) on the northern slopes of the Congo-Chad water-parting. As usual on such occasions, there is a great waste of life, many perishing in defence of their homes or even through sheer wantonness, besides those carried away captives. "A large number of slaves had been caught this day," writes Barth, "and in the evening a great many more were brought in; altogether they were said to have taken one thousand, and there were certainly not less than five hundred. To our utmost horror, not less than 170 full-grown men were mercilessly slaughtered in cold blood, the greater part of them being allowed to bleed to death, a leg having been severed from the body[191]." There was probably just then a glut in the market.
Arboreal Strongholds.
A curious result of these relations is that in the wooded districts some of the natives have reverted to arboreal habits, taking refuge during the raids in the branches of huge bombax-trees converted into temporary strongholds. Round the vertical stem of these forest giants is erected a breast-high look-out, while the higher horizontal branches, less exposed to the fire of the enemy, support strongly-built huts and store-houses, where the families of the fugitives take refuge with their effects, including, as Nachtigal assures us[192], their domestic animals, such as goats, dogs, and poultry. During the siege of the aërial fortress, which is often successfully defended, long light ladders of withies are let down at night, when no attack need be feared, and the supply of water and provisions is thus renewed from caches or hiding-places round about. In 1872 Nachtigal accompanied a predatory excursion to the pagan districts south of Baghirmi, when an attack was made on one of these tree-fortresses. Such citadels can be stormed only at a heavy loss, and as the Gaberi (Baghirmi) warriors had no tools capable of felling the great bombax-tree, they were fain to rest satisfied with picking off a poor wretch now and then, and barbarously mutilating the bodies as they fell from the overhanging branches.
