Muhammad al-Tunisi's account of his voyage to Darfur, translated from the Arabic into English as In Darfur, is one of the major sources for reconstructing the history of the Darfur Sultanate. Based on his experiences there and covering the late 18th century and early 19th century period of the Keira rulers, al-Tunisi describes his travels there, gender relations, the political offices, diet, domestic architecture, magic and local superstitions, local politics, and social and ethnic divisions. The multiethnic Darfur sultanate included a mix of various ethnic groups, including Zaghawa, Fur, Arab, Fulani, and others.
Due to al-Tunisi's own background as someone coming from an educated family and claiming descent from the Prophet, he and his father found favor and support in Darfur, even receiving a fief with rights to the taxation of villages. Because of his privileged position in Darfur and shared religion with the elites of Darfur, al-Tunisi's description of Darfur (and Wadai) occasionally provides more insights into the nature of the kingdom than that of later European travelers who were outsiders. Of course, al-Tunisi was still a biased outsider in another sense, bringing an Arab, North African perspective on Fur sexual mores, gender relations, and improper practices such as the possible human sacrifice.
Despite his own biases and sexism, al-Tunisi is an important source for documenting how extensive Darfur's links to the outside world were. The Sudanic belt, from Timbuktu and Mali in the west to Sinnar and Abyssinia in the East, and from the Maghreb and Egypt to Dar Runga and Dar Fartit in the south, the world of Darfur in this era was closely tied to regional, African, and global networks. The rulers of Darfur, for instance, used a royal seal made in Egypt. The sultan used the title of khaqan like the Ottoman sultan, too. An Egyptian fellah and musketeer named Zabadi served in the Darfur army. Darfur's ruler Tayrab invaded Kordofan.
In addition, after the French invasion of Egypt, Zawanah Kashif fled to Darfur, was well-received and then plotted to murder the sultan. Darfur was, through its trade links to Sinnar, Egypt, North Africa and the rest of Sudanic Africa, was clearly a participant in global trade. Political ramifications of the French invasion of Egypt also reached Darfur, just as epidemic diseases from the Islamic Holyland struck Wadai. While some may think of the Darfur sultanate as an insignificant, minor African kingdom, al-Tunisi's account indicates the opposite. Indeed, during this era, Darfur was particularly important on a regional level, even as succession crises fueled civil wars.
