There are three tribes whose political relations give them greater importance, namely, the Kél-táfidet, the Kél-n-Néggaru, and the Kél-fares. The first of these three, to whom belongs the above-mentioned Háj ʿAbdúwa, live in Táfidet, a group of three villages lying at the foot of a considerable mountain chain thirty miles to the south-east of Tin-téllust, and at the distance of only five good days’ march from Bilma. The Kél-n-Néggaru form an important family originally settled in Néggaru, a district to the north of Selúfiet; but at present they live in Ásodi and in the village Eghellál, and some of them lead a nomadic life in the valleys of Tin-téggana and Ásada. On account of the present Sultan (who belongs to them) being called Astáfidet, they are now also named Aushi-n-Astáfidet (the tribe of Astáfidet). The Kél-fares, to whom belongs the great, mʿallem Azóri, who, on account of his learning, is respected as a prince in the whole country, live in Tin-téyyat, a village about thirty-five miles east-north-east from Tin-téllust. The nominal chief of the Kél-owí is the amanókal residing in Asodi; but there is now another greater association or confederation, formed by the Kél-owí, the Kél-gerés, and the Itísan, and some other smaller tribes combined together; and the head of this confederation is the great amanókal residing in Ágades. This league, which at present hardly subsists (the Kél-gerés and Itísan having been driven by the Kél-owí from their original settlements, and being opposed to them almost constantly in open hostility), was evidently in former times very strong and close. But before speaking of the Kél-gerés and their intimate friends the Itísan, I shall mention those small tribes which, though not regarded as belonging to the body of the Kél-owí and placed under the special and direct supremacy or government of the Sultan of Ágades, are nevertheless more intimately related to them than to the other great tribes. These are, besides the Ém-egédesen, or the inhabitants of Ágades or Agadez, of whom I shall speak in the account of my journey to that interesting place, the three tribes of the Kél-fadaye, the Kél-ferwán and the Izeráren.
