Bilma is the southern oasis of the Kawar escarpment and the head of the salt trade: at the pans of Kalala beside it, salt is evaporated from brine and moulded, and natron and sodium sulphate collect.
Al-Muhallabi (tenth century) names Bilma as a town of Kawar within the kingdom of Kanem. Al-Idrisi (1154) calls the last inhabited town of southern Kawar Tamalma, which Marquart identified with Bilma (Mauny instead put Qasr Umm Isa here). Caravans from Kanem to the Fezzan water here before the dunes of the Tenere. Its most famous son, the poet and grammarian Abu Ishaq Ibrahim al-Kanemi, was born here when Bilma was 'a part of Kanem' (his biographers) and is at the Almohad court in 1200.

Where the sources disagree
- Identification of al-Idrisi's Tamalma (Marquart: Bilma) and Qasr Umm Isa (Mauny: Bilma; Lange: Achenouma) differs between scholars.
Evidence: Named by al-Muhallabi; al-Idrisi's Kawar towns are identified only by modern scholars.
On the map: The circle covers the oasis and the Kalala salt pans.
Primary sources for Kanem
Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.
- Exhortations and Reflections on the Quarters and Monuments: the chapters on Nubia and the Beja, al-Maqrizi (about 1417 to 1442, at Cairo). Two centuries late, but al-Maqrizi copied earlier books that are now lost, above all the account of Nubia by Ibn Salim al-Aswani, who went as Fatimid envoy to Dongola about 970 and described the Nubian king, his court, the eparch, the church and the land, which is the fullest description of Makuria ever written and still broadly valid in 1200; he also gives the Beja tribes, the oases, the baqt treaty and the Ayyubid campaigns against Nubia of 1173.

- The Book of Examples: the History of the Berbers and of the Muslim Dynasties of North Africa, Ibn Khaldun (1375 to 1379 at Qal'at Ibn Salama and Tunis, revised until 1406). Ibn Khaldun's tribal histories are the standard account of the powers that Almohad chronicles treat as background: the Banu Hilal and Banu Sulaym in Ifriqiya and Tripolitania and their alliances with the Banu Ghaniya and Qaraqush; the Zenata of the central Maghreb (Banu Marin, Banu Abd al-Wad, Tujin, Maghrawa) before their rise; the Sanhaja and the veiled peoples of the Sahara; the Masmuda and the Almohad tribes.

- The Book of Geography, Ibn Said al-Maghribi (Ali ibn Musa ibn Said) (about 1250 to 1275). Written two generations after 1200 but drawing on the travels of Ibn Fatima, a merchant who had been in the Sudan, Ibn Said gives the first clear picture of Kanem as an empire: the mai Dunama Dibalemi (reigned about 1210 to 1248), his capital Njimi, his Muslim subjects and his reach to the Fezzan, Tajuwa and the Zaghawa, with the Sao and other peoples on his borders.
