وهب بن منبه
In the 8th century, Wahb ibn Munabbih used Zaghawa to describe the Teda-Tubu group, in the earliest use of the ethnic name. Muhammad ibn Musa al-Khwarizmi also mentions the Zaghawa in the 9th century, as did Ibn al-Nadim in his "Kitāb al-Fihrist" in the 10th-century. Kanem comes from "anem", meaning south in the Teda and Kanuri languages, and hence a geographic term. During the first millennium, as the Sahara underwent desiccation, people speaking the Kanembu language migrated to Kanem in the south. This group contributed to the formation of the Kanuri people. Kanuri traditions state the Zaghawa dynasty led a group of nomads called the Magumi.
