Regarding the dialects of Sudanese languages, we find different formations from a single pronunciation. Therefore, one should not be surprised to find spellings that do not agree at all with the current or prevalent pronunciation. As for words whose spelling has become established through usage, the Orientalist Huda considered it not useful to be too precise about them. Finally, in all languages, there is a difference in the way some names are written and pronounced, which applies particularly to the Arabic language when writing Sudanese and Berber names.

The history of Sudan, despite its general title, only covers a part of Sudan. In fact, it speaks at length only about the Songhai Empire and the French occupation of the region on the banks of the Niger. It provides only a few paragraphs about the Mali Empire. The main focus of the author is on the city of Timbuktu, its capital, and the great role it played in the history of Sudan. The author has begun preparing his extensive work on its administration and on when this city began to decline. They hoped to gather from it centers of prosperity and wealth for their original countries. Their harsh treatment of the Sudanese resulted in the spread of hatred among these people, who are characterized by gentleness of morals and customs. As for Gadi, in this endeavor, he created a kind of popular resistance that initially prevented them from raising their flag over most parts of the country and from removing it from Timbuktu later.

The history of Sudan, as it has reached us, is divided into two main parts, each with general characteristics.
