And its imprints are clear and evident in the history of Sudan and its culture.

The Tuareg migrations played a role in the Islamization of West Africa. This is because these migrations carried Islam to the lands of Sudan and carried Arab culture, imprinting the lands with the Arab-Islamic character that continues to this day.

* The Second Gate The second gate is the eastern one, descending from the Red Sea coast, through which migrations crossed westward to central Sudan.

This is because as soon as Islam spread in Egypt, it began to seep into Sudan until northern Sudan later became an Islamic nation, linked to Egypt by the greatest spiritual relationship.
